Error "Your cache folder contains root-owned files, due to a bug in previous versions of npm" while "npx create-react-app example_app"

Question

When I was trying to create a new react app using npx create-react-app example_app, I get this error

[Your cache folder contains root-owned files, due to a bug in previous versions of npm which has since been addressed sudo chown -R 0:0 "/root/.npm"]

I even tried to re-install create-react-app again using npm i create-react-app, it is giving the same kind of error.

I assume after searching about it that it is due to some permissions issue. My current user doesn't have permission to /home/shubham/.npm where shubham is my username, but I am not so sure about this.

I have tried to solve this error using chown command as

sudo chown -R <username>:<groupname> /home/shubham/.npm" 

where <username> is Shubham and <groupame> is 1000, but it is still not working.

Request people to help me out. If you need any more information, let me know.

Solution 1

This worked for me:

sudo npm cache clean --force 

Solution 2

This is what helped me after going through the above answers. I hope it helps someone else too. After re-reading the npm error prompt, I adjusted the provided command to include the .npm path given in the error message. Below is a copy of my original error messages.

npm ERR! code EACCES

npm ERR! syscall access

npm ERR! path /home/vagrant/.npm-global/lib/node_modules

npm ERR! errno -13

npm ERR!

npm ERR! Your cache folder contains root-owned files, due to a bug in

npm ERR! previous versions of npm which has since been addressed.

npm ERR! To permanently fix this problem, please run:

npm ERR! sudo chown -R 900:900 "/home/vagrant/.npm"

[ExecStack] Exit code 243 Time 01:03

[error] Executing target-hook frontend-reqs failed.

[error] Command source:build:frontend-reqs exited with code 1.

Instead of using sudo chown -R 900:900 "/home/vagrant/.npm", I used sudo chown -R 900:900 "/home/vagrant/.npm-global". After that, I was able to use the previous command that caused the error with no issues.

Solution 3

Try sudo chown -R 1000:1000 "/home/shubham/.npm"

Solution 4

I had the same issue and several others while trying to update my npm packages. I will be honest I do not have enough knowledge of package handlers or why this fixed my situation, but I believe my version of npm and npx were causing the issues. I had errors immediately trying to install npx, node and create-react-app with my old and out of date version of npm.

I could not run npm install npx -g without --force. Once I did that I also ran npm install npm -g --force. After this I could already tell things were different.

After npm and npx were completely overwritten, I ran npm install node -g and npm install create-react-app -g without any weird problems. I created a new react app and started it error free.

(I also ran the cache command before all of this. sudo npm cache clean --force which I am unsure if it helped).

Solution 5

I had to do both the root folder and the root/.npm

sudo chown -R 1001:1001 "/root"
sudo chown -R 1001:1001 "/root/.npm"

i am also having this same issue

[Fabien Snauwaert]

Had the same thing inside Docker. Merely restarting the container fixed it.

Tried with this command, still getting the same error. [ npm ERR! Your cache folder contains root-owned files, due to a bug in previous versions of npm which has since been addressed. To permanently fix this problem, please run: sudo chown -R 0:0 "/home/shubham/.npm" ]

Did you also clean npm cache?

[Admin]

I have cleaned npm cache using "npm cache clean --force" as "npm cache clean" was giving error "As of npm@5, the npm cache self-heals". But now when i tried to run "npx create-react-app example_app”, it gets stucked while creating the app in middle of progress bar.
