Manually uninstalling create-react-app because npm uninstall not working - npm

I try to uninstall create-react-app globally
npm uninstall -g create-react-app
But it gives me this result
up to date, audited 1 package in 264ms
found 0 vulnerabilities
I have node version v17.3.0 (currently the latest stable version) and npm 8.3.0 (i've run npm update)
Is it sufficient to do this manually?
delete the alias /usr/local/bin/create-react-app (find it with which create-react-app)
delete the folder that it refers to: /usr/local/lib/node_modules/create-react-app/

Try clearing the npx cache with this command:
npx clear-npx-cache
This worked for me.

error installing cypress on windows 64 with npm

I'm seeing an error when attempting to install the latest cypress on my Windows 10 machine. I was using cypress 8.7 just fine. I deleted node_modules and package-lock.json and removed "cypress": "^8.7.0", from package.json.
Now installing cypress (9.1) I see this error:
npm install --save-dev cypress
npm ERR! Error: Cannot find module 'har-validator'
I see the same error when trying to use the old version too
npm install --save-dev cypress#8.7.0
System info from powershell:
node -v
> v16.8.0
npm -v
> 7.21.0
UPDATE:
My friend is able to install with dependency 8.7.0 in package.json, on OSX with nodejs 14.16.0.
This works today (2021-11-26) for me
npm install --save-dev cypress#8.7.0
There is a Bug in #cypress/request.
Take a look at https://github.com/cypress-io/request/pull/15
EDIT: There is a PR from one of the devs. https://github.com/cypress-io/request/pull/16
Looks like Cypress issue with latest versions. we have this problem for v8.7.0 today. "npm install har-validator" manually installed the missing har-validator module, that helped.

Change expo version from "^1.0.0" to "~41.0.1" (package.json)
npm install
npm start
if anyone is still facing issues, run
yarn add expo
if you don't have yarn installed on your computer then run
npm install -g yarn
and then run the first command.
I also received your message when installing the commands in the "React Navigation" set-up instructions and fixing vulnerabilities. The problem arises when using the command: npm audit fix --force. If you check the warnings after this command, you get
npm WARN audit Updating expo to 1.0.0, which is a SemVer major change.
So, try running: sudo expo update
If that doesn't work, try installing expo again with: npm install --global expo-cli and then update.
I'm also facing this error. So I run the npm command in the terminal.
npm install
You do not need to change the expo version. you just reinstall it.
Update the Expo to the latest version sudo expo update
Then install the updated npm packages npm install
Fix the issues in the packages npm audit fix --force
Run the Application npm start or expo start
Error ? you are trying to launch the expo framework yet it can't be found installed as part of your application modules
solution? simply find the latest version of Expo i.e for my case "expo": "^44.0.0", then go to your package.json file in your root folder, under the "dependencies" property plug-in that Expo version i.e
"dependencies":{
"expo": "^44.0.0",
}
close package.json file, then in your root folder run the command: npm install
after package installation is done run expo start
I simply used the expo update command.
It asked me
You are currently using SDK 1.0.0. Would you like to update to the
latest version, 44.0.0?
and I said yes, y not..
Every Thing was good to go with the npm start command
Cheers..
See the expo version - default "^1.0.0" , change ==> "expo": "~41.0.1"
Change expo to version "~43.0.0" in package.json
run npm audit fix --force in node_modules directory
here are my 2 cents. This worked for me :
Download latest version of nodejs - https://nodejs.org/en/download/
After installing nodejs reboot your computer
install : npm install --global expo-cli
Generate a new project with - npx expo-cli init projectName
cd projectName
npm start
you can run the below to install all dependencies
npm i
or to install exp
npm i -g expo-cli
This problem I faced was because of cloning a new project and trying to run it.
Always install the modules using the below command
I solved this by
npm install or npm i
I had same problem.
I simply used the expo update command.
You are currently using SDK 1.0.0. Would you like to update to the latest version, 44.0.0?

thats all
Is possible that you need an update try this command:
sudo expo update
Please try this
npm install --save expo --legacy-peer-deps
no need to edit package.json if expo version is not 1.0.0
You should register first on expo and then login
I had the same issue but after I logged in it was solved.
here is all about : https://docs.expo.dev/get-started/installation/
In my case, I clonned a Github repository and then used create-expo-app inside the repository directory. So, the command created a directory with the name of the app, but I was not in it: I was running the expo run command in the wrong directory.
Double check that the package.json is in the same directory in which you are running yarn or expo run to avoid this simple mistake.
The same error happened to me. But none of the other answers helped me. In my situation, I have node.js v18.12.1 installed. But when I check with nvm ls, the arrow points to "system", and on my system Xubuntu 22.04, the nodejs version installed is v12.22.9. So I needed to do nvm use 18, then
yarn add expo
expo start
Problem solved!
for window users
just type expo update into your terminal,

Can't remove Expo-cli

For some reasons I can't update or remove my version of Expo-cli.
I'm stuck on the 3.11.7 version. When I launch the update, it ends correctly but without being taken into account.
I've tested all the methods I've found but I haven't been able to uninstall it yet.
When I launch my project, it continues to launch normally with the v.3.11.7.
here are the commands line i already try :
yarn global remove expo-cli
npm -g uninstall expo-cli --save
sudo apt-get --purge remove expo-cli
yarn uninstall expo-cli
the expo --version commands is not working anymore ...
I need help please.
screenShot of the update request:
Please confirm OS. Mine is Windows 10.
Look in appdata for yarn or npm install directories. You can find the globally installed package files and delete expo.
Essentially an npm or yarn version other than the one you're using has installed the expo-cli and now your current version can't find it.
I solved this by deleting the expo files in that dir
Had the same problem. Here's how I decided it ( Win 10 )
Open cmd as administrator and type npm cache verify
After that type npm -g uninstall expo-cli --save, if it freezing terminate it.
Remove from your user folder ".expo" folder.
Than try npm -g uninstall expo-cli --save in cmd, if it freezing terminate it and open some expo project.
type yarn remove global expo-cli and then yarn add global expo-cli in the project
Hope it helps somebody else too.

Can anyone please help me I am not getting what is wrong here
Try to update the npm package:
npm install -g npm
And then install create react app again:
npm install -g create-react-app
And create the project again
I fixed it in three steps:
npm uninstall -g crete-react-app
yarn global add create-react-app
yarn create react-app my-app
It will work!

NPM Cannot read property '0' of undefined

After updated Node (upto v8.6.0) and npm (upto v5.5.1) I cannot execute command npm install.
After npm install I've error message:
npm ERR! Cannot read property '0' of undefined
What's trouble or I need downgrade node/npm ?
I had the same problem.
I removed both node_modules and package-lock.json and then did:
npm install
And it worked.
Edit by #OwlyMoly
Due to new updates and the restriction to old dependencies in package-lock.json is causing this conflicts. By doing npm install won't fix this issue. Instead by ditching npm_modules and package-lock.json and doing npm install will load a new node_modules and that supposed to be required by package.json. You have to commit the new package-lock.json along with your latest changes of the project.
Do 2 steps bellow (Window):
rm -rf ./node_modules to remove node folder
rm package-lock.json to remove package-lock.json file
then npm install to re-install the node modules
Just download and install latest Yarn which is also a node package manager, developed by facebook, but has a much better dependency management. Also update your node cli (optional).
And then, install your dependencies using yarn:
yarn install
or
yarn // short version of yarn install
No errors!
You can continue to use npm after you have installed all dependencies with yarn or continue with yarn....it's your choice.
I've made some tests:
nodejs#8.6.0 npm#5.5.1 - I have trouble and the test fails
nvm use 8.5.0
nodejs#8.5.0 npm#5.5.1 - I have trouble and the test fails
nvm use 8.4.0
nodejs#8.4.0 npm#5.5.1 - I have trouble and the test fails
npm install npm#^5 -g
nodejs#8.4.0 npm#5.4.2 - I have trouble and the test fails
nvm use 8.6.0
npm install npm#^4 -g
nodejs#8.6.0 npm#4.6.1 - no trouble, this fixes it.
Seems to be an issue with a combination of factors.
Some workarounds here:
https://github.com/npm/npm/issues/18238
npm 5.3.0 is broken for windows 10 after upgrading the nodeJS.
You should downgrade the npm, it is a temporary solution but works fine.
npm install -g npm#5.2.0
For me (npm#6.9.0) solved the issue by deleting node_modules and performing npm install, but without removing package.json.lock file.
Just remove both node_modules and package-lock.json and run: npm install
or
Just run: npm install -g npm#latest to upgrade it to the latest version
Try with nvm(Node Version Manager).it help you to install any node version for any project without any Error.
I found same problem when using npm version 5.5.1 to install babel-preset-stage-0
Solution:
I downgraded npm to version 5.2.0 and try to install again then it can solve the issue.
npm i -g npm#5.2.0
npm i -D babel-preset-stage-0
I bumped into this issue using nvs (Node Version Switcher - https://github.com/jasongin/nvs) node#10.15.3 and npm#6.9.0. The reason was a local package I had linked with npm link. The solution was to remove that folder.
In my case reinstalling node_modules have not fixed this issue.
Problem was with one *.ts file which was missing in source codes.
Do not know why It was not displaying compilation error, but adding this missing file to repository solved this issue.
Upgrading npm to version 7.5.4 did the job for me.
npm install -g npm#latest
What worked for me:
npm ci
Install a project with a clean slate
docs: https://docs.npmjs.com/cli/v7/commands/npm-ci
Deletes node_modules and installs everything based on package-lock.json, so no need to regenerate that
