I installed expo-cli using npm but after the successful installation, when i try to run expo --version, it shows that expo in nor recognized. I tried adding path to the environment variables but that doesn't seem to work. I have to start working on React Native. Are there any go throughs to this issue?
There is more than one solution to get
'expo' is not recognized as an internal or external command,
operable program or batch file.
Solution 1
Make sure you have installed it global
For npm
npm install -g expo-cli
For Yarn
yarn add -g expo-cli
Solution 2
Make Sure you have added
%USERPROFILE%\AppData\Roaming\npm
to your environmental Variable. I already faced this issue and solved by adding above to my environmental Variable
Solution 3
I don't know how to category this solution, Try to run
npm cache clear -f
in your terminal and
npm install -g expo-cli
I am trying running react-native from last 2 days but I am not able to run anything ,I followed official page for getting started and followed instructions carefully but everytime terminal gives me this error
npm -v 6.9.0
node -v v12.6.0
java -version
openjdk version "1.8.0_212"
these are the versions of requirements i have installed
I copy pasted
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
these inside of .bashrc file in home
can anyone save me please
React Native site has good installation guide for React Native CLI on Linux, but sometimes command npm install -g react-native-cli fails with error
checkPermissions Missing write access to /usr/lib/node_modules
because only root can access directory where NPM install global packages. You might want to run sudo npm install -g react-native-cli but you shouldn`t.
(If you did it, run please:
sudo chown -R $(whoami) ~/.npm
to eliminate consequences).
The most preferred solution will be changing npm’s default directory:
create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
Open ~/.bashrc (or ~/.profile) file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.bashrc
Now you can install react-native-cli globally without using sudo:
npm install -g react-native-cli.
After that react-native init should work.
If I do:
npm init
npm install --save topojson
I end up with a package.json file and node_modules directory, all looking correct. But if I then do:
topojson
I see:
-bash: topojson: command not found
Why?
The answer to this issue turned out not to be related to npm - npm install topojson no longer installs a command-line tool called topojson. Confusingly, it used to, but the package has changed.
try this step
install globally using -g
1. install nodejs http://nodejs.org/
2. install npm https://npmjs.org/doc/README.html
3. run npm install -g topojson in your command prompt
4. use the command prompt to cd to the geojson file
5. run topojson -o myNewTopojsonFile.json myOldGeojsonFile.json
While installing the dependencies of vue-cli, vue is not identified. Why?
rm -rf node_modules and npm install again
have a look here
Add sudo before yarn when installing
yarn global remove #vue/cli
sudo yarn global add #vue/cli
vue
I had the same issue for a while.
TL;DR
npm install #vue/cli-service --save-dev
As the documentation specify it is a development dependency https://cli.vuejs.org/guide/#cli-service
The CLI Service (#vue/cli-service) is a development dependency. It's an npm package installed locally into every project created by #vue/cli.
Origin
I had a fresh install of nodejs
And just did
>> sudo npm install -g #vue/cli#latest
>> vue --version
#vue/cli 4.5.8
The issue
The issue presented like this
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
/bin/sh: 1: vue-cli-service: not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
The fixes:
npm install #vue/cli-service --save-dev
Which led me straight to another error message
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
ERROR Error: Cannot find module 'vue-template-compiler/package.json'
Which I fixed the same way
npm i vue-template-compiler --save-dev
And now it is working fine.
Installing current version without permanently installing vue-cli.
npx #vue/cli create appname
It shows the vue executable is located at /home/alisha/.local/bin. So probably this location is not there in your $PATH.
You should be able to run the vue commands if you provide the full path, like:
~/.local/bin/vue create hello-world
You can also see if that directory is in your PATH by running some command like:
echo $PATH | grep '.local/bin/'
If it's there, you would see it, otherwise you can add it to your path by placing it in your ~/.profile.
Edit ~/.profile and add the following at the bottom of it.
PATH="$HOME/.local/bin:$PATH"
Hope it helps!!
I had the same issue while making a build for production.
You will require vue-cli to be installed. Use below command to install the latest version.
npm install -g #vue/cli#latest
Then
npm install
Might have to do with you having an old version on your computer:
Warning regarding Previous Versions
The package name changed from vue-cli to #vue/cli. If you have the previous vue-cli (1.x or 2.x) package installed globally, you need to uninstall it first with
npm uninstall vue-cli -g or yarn global remove vue-cli.
You can find it here: https://cli.vuejs.org/guide/installation.html
THIS FIXED THE ISSUE FOR ME:
After running
sudo npm install -g #vue/cli
I ran
sudo nano $HOME/.profile
and pasted the following line
export PATH=$PATH:/home/chike/.npm-global/bin
after writing the code, next thing I did was Ctrl + O, ENTER and Ctrl + X then wrote
vue init webpack myapp
When you install vue using cli that time you got the path of vue.Now you can copy the bin folder path.
In my example /home/sublime/.npm-packages/bin
Now you export the path below command
export PATH=$PATH:/home/sublime/.npm-packages/bin
I solved mine by running (add sudo if needed)
npm i -g vue-cli#2.9.6
npm i -g #vue/cli
Got similar issue when deploy vue project in jenkins.
Here is what I did:
Add node's bin/ dir, to jenkins user's .bashrc file.
e.g
# node
NODE_HOME=/home/dev/.nvm/versions/node/default
PATH=$NODE_HOME/bin:$PATH
Tips - about nvm & yarn
When you manage node version via nvm, make sure you already choose the node version in terminal. e.g:
nvm use stable
node -v
If you use nvm, and installed yarn via npm, then better install vue-cli via npm not yarn, otherwise the vue executable is not placed into node's bin/ dir, at least that's the case in my tests, and as a result will cause you fail to find the vue command.
Using Yarn on Ubuntu it is installed to ~/.npm-packages/bin/. You must add this directory to your PATH. For example run the following command, close your terminal and open a new one.
user#machine:~$ echo 'export PATH="$PATH:~/.npm-packages/bin/"' >> ~/.bashrc
Note: if the file ~/.bashrc does not exist then simply create it.
Following worked for me:
First remove all the existing ones:
yarn global remove #vue/cli
yarn global remove #vue/cli-service
sudo yarn global remove #vue/cli
sudo yarn global remove #vue/cli-service
Then add #vue/cli using sudo:
Note: use sudo if required
yarn global add #vue/cli
yarn global add #vue/cli-service
Then, the final thing to do is to RESTART the terminal.
vue --version
#vue/cli 4.5.9
If you already got a project, the only two things you need to do is:
Delete the directory node_modules (it is safe, since it is not under git and will regenerate in the next step)
In the command-line write yarn install (it will install everything you need)
If you start installing vue-cli manually in a existing project, it the package.json and package-lock.json will be updated. If you already did. Do a checkout from git, and follow my steps above
This may be a problem caused by version conflicts. "export PATH=$PATH:" This is really useful in some cases. But if you are also like me, after trying the direct “export path” method in the comment above, restarting the terminal still can not execute the situation, you can try this way.
Uninstall Vue
npm uninstall -g #vue/cli
Check the local-global npm package installation path, vue is installed in this directory, check if it has been removed.
npm root -g
Install vue (you can check with https://cli.vuejs.org/#getting-started to find the latest command)
npm install -g #vue/cli
Create a connection to the /usr/local/bin directory(You need to find the vue.js path after the local installation first, then replace this path with your latest local install path:/Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js)
ln -s /Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js /usr/local/bin/vue
View version number
vue -v
I was getting the same error because Node.js was not installed. My issue got resolved by installing Node.js using the following command:
sudo apt install nodejs-legacy
To see if you already have Node.js and npm installed and check the installed version, run the following commands:
node -v
npm -v
If both are installed then follow the steps here:
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
I installed the package using yarn global add #vue/cli on my Ubuntu box and found the binary in /home/vonkad/.yarn/bin.
I had to modify my /home/vonkad/.bashrc and add the directory to the path export PATH=$PATH:/home/vonkad/.yarn/bin.
To fix this situation, I had to add the following line to my .zshrc (maybe in your case is .bashrc)
export PATH="$(yarn global bin):$PATH"
Effectively, the yarn global bin is a folder where vue (vue-cli 3) was placed.
What helped me
mac os catalina with zsh terminal
Uninstalled node and npm using https://www.positronx.io/how-to-uninstall-node-js-and-npm-from-macos/
Downloaded node/npm from https://nodejs.org/en/download/current/
sudo npm install -g #vue/cli
vue --version (#vue/cli 4.5.4)
I faced the same issue and now resolved. In my case I installed Node.js and NPM using the default Ubuntu repository by using this command sudo apt-get install nodejs npm
The problems seemed like those 2 packages are not well maintained so it caused some bugs.
So I purge those packages and reinstall it from nodesource which is officially recommended way to install (reference: Installation instruction from nodesource) using these commands.
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
Then reinstall #vue/cli again
sudo npm install -g #vue/cli
Now these issues have gone. Hope it helps some programmers.
You need to install vue via sudo like explained in the doc:
https://cli.vuejs.org/guide/installation.html
If you have WSL2 running and you use zsh like me, just add
yarn global add #vue/cli
# add this line to ~/.zshrc
export PATH="$HOME/.yarn/bin:$PATH"
$ vue --version
#vue/cli 4.x.xx
You can try the following code install see
npm install --global vue-cli
vue init webpack <YOUR-PROJECT-NAME-HERE>
cd <YOUR-PROJECT-NAME-HERE>
npm install
npm run dev
I installed truffle through npm with the following:
sudo npm install -g truffle
but when I run truffle list on the console it just gives me
bash: truffle: command not found
I had a similar problem. I ran npm i -g truffle and then when I tried to run truffle init I got an error: zsh: command not found: truffle. What solved it for me is to create a local node_modules with truffle installed in it, and then run that copy.
run npm init and make a new npm project
run npm i truffle
run ./node_modules/.bin/truffle init and it should work!
Please make sure you have the latest version of npm and node installed. I had the same issue, I updated npm and node to latest version and it worked.
npm install -g truffle works.
After installing truffle:
npm install -g truffle
Run on your project folder:
npx truffle init
I did it on a Virtual box and had the same issue, but it worked after I restarted the computer. Hopefully that works for you too
You should add the following to your path system variable.
C:\Users\UserName\AppData\Roaming\npm
(This folder contains the truffle.cmd file)
I have tried and it works.
I tried everything. Followed the instruction on official truffle website and above answers.
Still it didn't seem to worked.
Finally, this worked for me.
Go to C:\Users\Username\AppData\Roaming\npm
There you will find truffle.cmd Double click on it and your done.
npm i truffle does the exact same thing as npm install -g truffle except that installs it globally, and without -g it will be installed on the local folder. Try to update the npm, node, and probably you have a broken node installation from previous versions.
Using npm install -g truffle worked for me instead of npm i truffle
Nothing above worked for me, but I did:
nix truffle unbox react
truffle develop
atom . //opens up the react file project in the atom platform
Try to start with your command like
npx truffle <your command>
You should add C:\Users\UserName\AppData\Roaming\npm (it contains truffle.cmd file) to the path user variables. I have tried and it works
If you have a custom path for your packages, then make sure that you are exporting it when the terminal loads.
For bash:
nano ~/.profile
For zsh:
nano ~./zshrc
And add your custom path, most of the time this will be "npm-global".
export PATH=~/.npm-global/bin:$PATH
These are two simple steps the properly solve this problem for Linux Users:
1- Configure npm to install software globally in your home directory as follows :
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
2- If you are using bash, then execute the following:
echo -n "export PATH=~/.npm-global/bin:$PATH" >> ~/.profile
However, if you are using zsh instead, then execute the following command:
echo -n "export PATH=~/.npm-global/bin:$PATH" >> ~/.zshrc
Note that, if you are using both bash and zsh, it is better to execute the two commands above.
