Answer 1

Apparently, you need to set ReadOnly=false for the files it accesses

Answer 2

I ran into this with nuget restore after doing a git clean -fd with VisualStudio open: the packages/ directory was marked for deletion, and while several files were deleted, the packages/ folder itself was not as VisualStudio had the .nupkg files open.

Once I closed VisualStudio and re-ran git clean, it removed the packages/ directory and then nuget was able to restore everthing correctly.

Answer 3

My collegue just got this error, during all "worked on my machine". After some research I found out that the *.nuspec file for some reason wasn't added to the version control.

Answer 4

Try running it as administrator.

Answer 5

I was running into a similar problem. I attempted to restart Visual Studio, Run as Administrator (Which I always do), Set the folder attributes to ensure the 'Read-Only' flag was off. Regardless, whatever I did, I still encountered the error "access to the path is denied" when updating my Nu-Get packages.

I was able to fix the issue by updating packages one-by-one. Choosing instead to go through each dependency and updating it. Once the dependency was updated I would choose another, sometimes the same error resulted in which case I would choose another until all my packages were successfully updated.

It appears in my case the Nu-Get packages had to be updated in a particular order.

Hope this helps someone out there

I had this problem and it turned out windows had an update waiting for the next restart. Cleared with no problem after restarting and waiting for the update.
