NuGet.exe pack gives access to the path is denied

Question

When I try to pack my MVC project ( NuGet.exe pack ) I get:

NuGet.exe : Access to the path '...' is denied.

This happens to be the case for all files in the content and script folder of my MVC solution. If I remove the readonly flag on all these files NuGet.exe is able to create the NuGet package.

Why do I have to remove the readonly flag? Is there another way?

I'm using TFS which specify the readonly flag on all files under source control.

I am running:

• NuGet Version: 1.7.30402.9028
• Microsoft Visual Studio 2010 Version 10.0.40219.1 SP1Rel

I'm using the NuGet.exe that you get when you install the NuGet package NuGet.CommandLine which is located at http://nuget.org/packages/NuGet.CommandLine .

Answer 1

显然，您需要为其访问的文件设置ReadOnly=false

Answer 2

尝试以管理员身份运行它。

Answer 3

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.

In my case something happened when switching branch in git. Everyone lost execute permissions for Nuget.exe.

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

Answer 6

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 7

In order to Restore nuget packages, remove read only permissions from the folder level (for windows). Clean the solution and Build. It will works

Answer 8

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.

Answer 9

就我而言，它是最近修改的 git repo root 中的*.gitattributes （错误地），因此 git 开始在构建服务器上检出nuget.exe并将所有LF转换为内部的CRLF ，使其不可执行。

使用管理员权限运行Visual Studio。
