I am a newbie in all this stuff. Hope for your understanding.
Let me clarify the issue:
I am trying to start react native app through expo cli. So tried to start npm install expo-cli --global to install npm globally. I got these errors:
Screen_1
Screen_2
It also says that I lack permissions to access it. How can I allow permissions?
Even when I try to start it locally I got the same issue. Your help is appreciated.
although this solution is not the best and the safest solution exists, this worked for me and that make sense because all the problem we had with the errors is the permission problems. so you can use this command and ignore those permission problems :
sudo npm install expo-cli -g --unsafe-perm
I was having the same problem with npm install -g expo-cli, having "MODULE_NOT_FOUND",
I installed yarm with brew, just in case you do not already have it:
brew install yarn
and then use:
yarn global add expo-cli
to create a project you can:
expo init nameOfTheNewProject
and choose a template in the console.
Finally run the project with
yarn start
Let me know if it works for you!
You did not mention which os. This answer working for any operating system (ubuntu in my case)
I'm also getting permission errors when running
sudo npm install --global expo-cli
Which I don't really how this can happen - as this also happens for the superuser!
For me it works when I install the client locally into the project
cd <new-project-dir>
npm init # init npm project
npm install expo-cli
Now you can use the client in this project like this:
npx expo-cli # e.g. npx expo-cli init <project-name>
npm cache clean --force
This will solve the issue
Try using npm install -g expo-cli#3.5.0 this worked for me, it may work for you.
You can try this command:
npm install -g expo-cli
or,
yarn global add expo-cli
You have to run the command as administrator from a command prompt on windows and not bash. Had me stumpt for bloody ages!
You need administrator privilege. So when you open command line interface, just right click and run as administrator
This will solve the problem
I guess, this issue comes from permission or node version , if you get this error when the node module is being refreshed ---> This is definitely a permission issue. Disable your Antiviruses or change permission manually check this as well.
First run npm cache verify, then run sudo npm install --global expo-cli.
Did work for me indeed after trying so much.
Follow the steps
First, run npm cache verify.
Open Windows PowerShell as administrator and run npm install expo-cli
--global --no-optional command.
npm cache clean --force then npm install --unsafe-perm -g expo-cli
It is likely you do not have the permissions to access this file as the current user.
The best way to solve this problem is to reinstall npm with a node version manager.And you don't need to remove your current version.
About node version manager
use nvm or n with OSX or Linux
use nodist or nvm-windows with windows
Upgrade Node version to +10
Then do
sudo npm install expo-cli -g
This worked for me. I hope this would solve your problem!
sudo npm install expo-cli -g --unsafe-perm=true --allow-root
If any of the solutions above result in success, please follow the steps below:
Uninstall Node.js
Restart your pc/mac
Download latest version of the Node.js (https://nodejs.org/en/)
Open cmd as admin mode or use "sudo" before the command line on Mac.
npm install expo-cli --global
I hope it can help
In my case, I deleted two files then everything worked. The two files are in this path: C:\Users\{Username}\AppData\Roaming\npm under the names 'expo.ps1' and 'expo-cli.ps1'
Then run:
npm i -g expo-cli
re-install node.js, it works for me
First update Node.js to the latest stable version and then again try to install expo ad clean before expo folders that are being created in below location
C:\Users\{{computer_username}}\AppData\Roaming\npm
If it's throwing error in visual studio code, try from cmd, was facing same error but solved through this way
npm install -g expo-cli
try going into windows resource monitor and terminating adb.exe (android resource bridge). This worked for me after searching for solutions for days. I tried this after verifying cache, clearing cache, you name it.
As a Debian 10 buster user I got the same permission error while using this command: sudo npm install expo-cli --global.
The problem was solved by installing expo-cli with yarn package manager and the command below: sudo yarn global add expo-cli.
For Windows User :-
Open your Powershell and type:
npm install expo-cli --global
This worked for me after trying and reasearching for hours.
Note:Don't Use cmd or any other terminal and also don't type npm install expo-cli -g as it is written in the react native docs. It would always show up an npm error.
For windows
Follow these steps carefully
open the command prompt and run it as administrator.
recommended npm uninstall --global expo-cli.
run the command npm cache clean --force.
run the command npm cache verify .
now run the command npm install --global expo-cli
dont run command like npm i -g expo-cli or npm install -g expo-cli.
7.Make sure you run the command mentioned in the 4th step ONLY.
thankyou.
I had this problem in Windows 10, to be able to install the latest version (I had no choice since it broke the current one). I had to install the latest version of Python (3.8.0) and then run npm install --global --production windows-build-tools as an administrator, then I was able to run again: npm install expo-cli --global to install the version 3.8.0 of the expo-cli
Here is the solution and 100% working. I am working with Windows and not sure abut Linux.
Open cmd and
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
then press yes
Now run the command to start your project
npm install -g expo-cli
I had previously removed Expo from my Windows machine and encountered this error whilst trying to reinstall. Reading the error message solved the problem.
npm i expo-cli -g --legacy-peer-deps
Using this command in 'PowerShell' installed expo successfully.
If anyone else has this problem here is my fix, go to Finder, in the input field (search box) type in /usr/local/lib then press CMD + SHIFT + G press the OK button or whatever pops up, then CMD + SHIFT + . and delete the NVM file i deleted the expo folder too. Then go to this link https://changelog.com/posts/install-node-js-with-homebrew-on-os-x
follow the instructions and install brew, node, etc. Last step go to your terminal and type sudo npm install expo-cli --global
First: I upgraded my mac version 10.13 to 10.15
Then I downloaded homebrew, Watchman, Git and Node.js
Finally I ran this command sudo npm install --global expo-cli --legacy-peer-deps
If you have any further questions check the docs out: https://docs.expo.dev/get-started/installation/
Sometime, I use npm not work.
I try a lots times run with npm but fail for expo cli.
Please try yarn global add expo-cli
It wills save your time ^^.
I was trying to install expo-cli with my company npm registry configured.
I've created 2 differents profiles using npmrc and using the profile with https://registry.npmjs.org/ solved the issue.
I create a node application and it is running on the local server. I need to run it on my online server. I have to install npm. When I run the command npm install I got this message.
How can I fixed this issue?
try using
sudo npm install -d
npm should not need sudo except for global installs. Let's start with "how did you install node"? If you're on OSX, use brew to install the latest version, if you're on Windows, grab the installer from nodejs.org, if you're in linux, you should already know what to do
I get this error message when I try installing feathers from npm
npm WARN deprecated nomnom#1.8.1: Package no longer supported. Contact support#npmjs.com for more info.
npm WARN deprecated babel-preset-es2015#6.24.1: 🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!
Help!!
As Vasan pointed out in the comments, running
npm install -g #feathersjs/cli
from the command prompt on Windows installs a file feathers.cmd in the folder:
%APPDATA%\npm
If this folder is not on your PATH, then feathers will not be recognised as an executable - it appears that the global install doesn't add it to the path automatically.
Editing system environment variables to add this folder to your path should make the feathers cli tools available.
Note that after altering your path you may need to restart your terminal for the updated path to be available.
Its very simple, if you have an earlier version installed, uninstall the old feathers-cli using:
npm uninstall feathers-cli -g
Then install #feathersjs/cli and upgrade a project by the following commands:
npm install #feathersjs/cli -g
cd path/to/project
feathers upgrade
I also faced with the installation issue. But got an error: 404 Not Found: babel-messages#^6.23.0. I've solved it when run npm install #feathersjs/cli -g through the windows terminal (cmd). Before that I was running it on bash.
This issue also occurs when installation is ran using Admin credential(Windows 10), reinstall without elevated cmd/powershell credential also solved the problem.
Please check the below image and give a solution for this, I am stuck, please help.
Finally was able to fix the issue and install ionic, so I was hoping I should share it, if anyone having the same issue please check if my steps also works for you.
Turn off Windows Firewall
Turn off any/every Antivirus or windows defender you are running.
Clear npm cache, run - $ npm cache clean
Remove Nodejs
Restart PC
Install latest version of Nodejs
Clear npm cache again, run - $ npm cache clean
[important] First only install cordova, run - $ npm install -g cordova
Then install Ionic, run - $ npm install -g ionic
Hopefully it will work, this how I was able to fix my issue.
You have to install Node JS 0.12.6 Version,
and after that, use:
$npm install -g cordova ionic
in DOS (cmd). It will install ionic and Cordova.
WARN [config]: config.configure() is deprecated, please use config.set() instead.
WARN [plugin]: Cannot find plugin "karma-phantomjs".
Did you forget to install it ?
npm install karma-phantomjs --save-dev
INFO [karma]: Karma v0.10.2 server started at http://localhost:9018/
WARN [launcher]: Can not load "PhantomJS", it is not registered!
Perhaps you are missing some plugin?
Getting this error. When running npm install karma-phantomjs --save-dev I get an error.
npm ERR! 404 'karma-phantomjs' is not in the npm registry.
I installed karma-phantomjs-launcher --save-dev but i still get an error when running grunt watch.
Anyone else run into this issue?
npm install karma-jasmine --save-dev
npm install karma-phantomjs-launcher --save-dev
Then add the following line to karma.config.js
plugins : ['karma-jasmine', 'karma-phantomjs-launcher']
I got tripped up by this today running
karma: 0.13.7
karma-phantomjs-launcher: 1.0.0
What isn't very obvious is that the launcher has a dependency on:
phantomjs-prebuilt
So if you, install this locally everything should run fine, eg:
npm install phantomjs-prebuilt --save-dev
After some research I realized that I needed to run:
npm install -g karma#canary phantomjs karma-phantomjs-launcher
Once I ran that I went back into my karma-unit.tpl.js file and instead of karma-phantomjs, I changed this to karma-phantomjs-launcher.
Now when I execute a command like grunt build, I get no error regarding phantomJS
This is an issue still open on the repo: #31
Strangely enough the following worked for my Debian based system:
apt-get install libfontconfig
How did I get into this? Reading a comment from the ticket. Hope this will help for others too :-)
I'm running in a CentOS 7 Docker container. Had similar issue.
Had to:
yum install -y tar bzip2 freetype fontconfig
Then
npm install phantomjs --save-dev
worked without errors, which allowed
npm install karma-phantomjs-launcher --save-dev
and that allowed
gulp test
to run without Karma or PhantomJS errors.
Today I had the same. I deleted all the temporary directories and, after rerun it worked.
Before that i also reinstalled phantomjs but without success. It's possible that this influenced, anyway (but i think deleting the temporary directories did the job). Anyway, after deleting temporary folders you can try, if it didn't work you can reinstall phantomjs and also other stuff as other users already wrote.
