Error: EPERM, unlink
System info: Bower version: 1.3.12 Node version: 0.10.35 OS : Windows8
I tried below workaround but nothing is worked out.
Its not worked for me please suggest me some solution
I got this problem, yes in Windows 10.
Solution?
To disable indexing of contents for that folder (the one containing the package.json)!!
On Windows Shell (File Manager), follow this steps:
- Right click on the folder with the error, choose 'Properties'
- Click the 'Advanced...' button.
- Uncheck the checkbox 'Allow files in this folder to have contents indexed in addition to file properties'.
- Press 'OK'.
- On the previous Properties dialog (visible again), press 'Apply'
- Check radio button 'Apply changes to this folder, subfolder and files'.
- Press 'OK'.
- (can take a while)
- Press 'OK' (to close properties dialog).
- Works!
In my case, it was permissions - probably in the node_modules tree, but just to be sure, I granted myself ownership and rights to the entire project tree which fixed the problem.
Right click on your project folder, select Properties, then the Security tab and click the Advanced button. Set yourself as the owner and grant yourself full permissions. Check "Replace all child object permission..." and OK.
My case was even simpler... a process was still using one of the files in the folder that required deletion. Killing the task responsible enabled me to install correctly.
You don't have the permissions necessary to remove that file. Somehow you have caused npm/bower to do things that conflict with the default windows permission system.
It would probably be simplest to remove bower
and npm
and reinstall them, and then update your npm
to the latest version following the instructions here https://github.com/npm/npm/wiki/Troubleshooting
For a quick fix that might help, try this in a CMD window (you may need to start it as Administrator):
cd C:\users\path\temp
cacls . /T /E /C /G Everyone:F
That grants Everyone
Full Control
over your temp directory, which is potentially a security risk. However, it should make it possible for npm
and bower
to clean up old files.
I recommend you try reinstalling node
, npm
, and bower
.
For me, remove the indexation has solved my problem.
But the indexation was back after to have recreate the folder. In this case the solution is one the options follow:
I am on Windows 10 and this action seems resolve my problem permanently.
Had a similar issue - npm install had worked fine for months, but we upgraded a few libraries and started getting the same error.
Ended up switching from NPM to yarn , which did work.
I got the same error and it has been solved by using correct version of node for npm. Check your package.json 'engines' and your installed node version. You can use Node version manager if you need to have several versions installed and switch between them: https://github.com/coreybutler/nvm-windows/releases
