When I execute npm install I get this error
npm ERR! Error: EPERM: operation not permitted, rename C:\projects******\node_modules\react-async-script' -> 'C:\projects*******\node_modules.react-async-script.DELETE'
npm cache clean beforenode_modules open In my situation this helped:
Before proceeding to execute these commands close all VS Code instances.
clean cache with
npm cache clean --force
install the latest version of npm globally as admin:
npm install -g npm@latest --force
clean cache with
npm cache clean --force
Try to install your component once again.
I hope this fix your issue. If not, you may temporarily disable your antivirus program and try again.
I got it working when tried npm install with a force option to fetch remote resources even if a local copy exists on disk. Try running
npm install --force
Updated For some of my colleagues this solution was not working. But we tried using yarn instead of npm. It works (faster as well) without any issues all the time
yarn install [package-name]
If you want to avoid the --force option (which is always a better approach), I suggest making sure that you have stopped running the project, as this is usually the main reason for locking the files in almost 90% of the cases I have seen
1- In Angular stopping ng s and in React stopping npm start usually solves this issue because usually this error happens if a development server is running the project as it locks some files & then npm can't update them thus throwing this error
2- If the above doesn't work, then try closing the code editor that has the workspace opened in it (maybe it was locking some files or something)
So try closing the code editor & running:
npm install
3- If still it doesn't work, then maybe you can try the --force option
npm install --force
I was getting that same error and according to https://github.com/Medium/phantomjs/issues/19 it could be caused by your antivirus software. I disabled mine for the duration of the install and executed "npm install" on cmd as admin and it worked. Hope this helps.
I was getting the same thing. I didn't find this anywhere but it hit me that our VMs tend to change files to a read-only state. So I opened package.json's file properties and deselected Read-only in the "General" tab.
Steps
package.json file.This is a typical error caused by Antivirus. There is a workaround for cases like mine, where I can't disable A/V (Company Policy).
You have to change the polyfills.js inside Npm package:
[NODE_HOME]/node_modules/npm/node_modules/graceful_fs/polyfills.js
Look for this statement:
if (process.platform === "win32") {
Inside of this statement, there is a timeout making a retry in case of error. The problem is that in some cases, after the timeout, the file is still locked by the A/V. The solution is rip out the timeout and let this statement in loop. The change with the previous code commented:
if (platform === "win32") {
fs.rename = (function (fs$rename) { return function (from, to, cb) {
var start = Date.now()
var backoff = 0;
fs$rename(from, to, function CB (er) {
if (er
&& (er.code === "EACCES" || er.code === "EPERM")
/*&& Date.now() - start < 60000*/) {
console.log("Retrying rename file: " + from + " <> " + to)
fs$rename(from, to, CB);
/*setTimeout(function() {
fs.stat(to, function (stater, st) {
if (stater && stater.code === "ENOENT")
fs$rename(from, to, CB);
else
cb(er)
})
}, backoff)*/
if (backoff < 100)
backoff += 10;
return;
}
if (cb) cb(er)
})
}})(fs.rename)
}
I have had this issue multiple times only in Windows I try these in the order usually.
npm install --forcenode_modules/Usually trying npm install after one of those steps will resolve it.
I did the following:
npm install -g
[email protected] c:/users/[username]/AppData/Roaming/npm-cachenpm cache clean --forcenpm install.I remounted my window disks with the metadata flag, and instantly helped: https://devblogs.microsoft.com/commandline/chmod-chown-wsl-improvements/
after that no need anymore to use sudo for npm commands as the metadata keeps windows and linux file/directory permissions in check.
I had the same problem after updating to npm to 5.4.2, npm start giving the same error for most npm commands. Some solution suggest to run it with --no-optional, but it didn't always work.
Others suggested to downgrade, but I didn't want to downgrade.
I suspected that there was a problem with the installation, not sure what it was.
So I re-updated my npm:
npm i -g npm
and worked fine since then.
npm was failing for me at scandir for:
npm install -g webpack
...which might be caused by npm attempting to "modify" files that were potentially locked by other processes as mentioned here and in few other github threads. After force cleaning the cache, verifying cache, running as admin, disabling the AV, etc the solution that actually worked for me was closing any thing that might be placing a lock the files (i.e. restarting my computer).
I hope this helps someone struggling.
For some, AppRoot\npm folder could be an issue. Sometimes the AppRoot folder is marked as network shared and thus Antivirus blocks the stuff. Follow below link for complete solution.

I hope this helps.
My answer is to do npm cache clean --force first. Then run npm install -g [email protected] to install npm 5.3.0 version. for me, this npm version works with no trouble.
