Having watched my Windows Defender Virus Scanner start hogging the CPU while running my script  I suspect this is the actual cause  but as I don t have the ability to tweak those settings as I m in a commercial domain  As my script fails while doing npm install  I simply tried this instead npm install --verbose  which allowed it to run perfectly  It probably doesn t fix the underlying issue  but it allowed my install to download and extract all dependencies to my local cache at least once and therefore  everything worked a lot smoother  I presume this command slows the writes read to the disk by a fraction of a second  while its writing to the Command prompt and this gives the virus checker  just enough time to finish its work  without creating a deadlock on the files

There seems to be many solutions out there that worked with downgrading npm versions   For me  the solution was   npm install -force   I tried the downgrading of npm versions  modifying my npm prefix config to match the npm directory  and clearing cache   None of these worked  but apparently they worked for others  so it may be worth a shot

In my case  i was facing similar issue while running multiple instance of  npm install  on VM used for build Windows   Since it was a VM used only for build there was no other program locking the files  I tried disabling various antivirus settings which didn t worked   npm cache clear  and  npm cache verify  worked but it was not a right solution for me as i cannot guess when somebody will trigger a build job from Jenkins for different release environment leading to multiple instance of  npm install  and hence i cannot add it to the build script nor i can go login to VM and clear delete the cache folders manually every time   Finally  after some research  I ended up running  npm install  with separate cache path for each job using following command   npm install --cache path to some folder   Since  all the jobs running at the same time now had a separate cache path rather than the common global path  Users AppData Roaming    this issue got fixed as the jobs were no more trying to lock and access the same file  from the common npm cache   Please note you can install a single package with a cache path as follows   npm install packageName --cache path to some folder   I was not able to find this way of giving a cache path in npm documentation but i gave it a try and it worked  I am using npm6 and looks like it works since npm5    Refer  How to specify cache folder in npm5 on install command   This solution should work for other scenarios as well though may or may not be a good fit

I had the same problem on Windows   The source of the problem is simple  it is access permission on folders and files   In your project folder  you need   After cloning the project  change the properties of the folder and change the permissions of the user  give full access to the current user   Remove the read-only option from the project folder   Steps 1 and 2 take a long time because they are replicated to the entire tree below   Inside the project folder  reinstall the node  npm install reinstall -g  Disable Antivirus   optional  Disable Firewall   optional  Restart PC  Clear the npm cache  npm clear  Install the dependencies of your project  npm install    After that  error  Error  EPERM  operation not permitted  unlink  will no longer be displayed   Remember to reactivate the firewall and antivirus if necessary
