Running 'dotnet restore' on /home/limup/Documents/Projetos/Limup/salao/salao.csproj...
/usr/share/dotnet/sdk/3.1.101/NuGet.targets(123,5): error : Unable to obtain lock file access on '/tmp/NuGetScratch/lock/b19d3901039706ea82571abad7c98ec690508d4b' for operations on '/home/limup/Documents/Projetos/Limup/salao/obj/salao.csproj.nuget.cache'. This may mean that a different user or administator is holding this lock and that this process does not have permission to access it. If no other process is currently performing an operation on this file it may mean that an earlier NuGet process crashed and left an inaccessible lock file, in this case removing the file '/tmp/NuGetScratch/lock/b19d3901039706ea82571abad7c98ec690508d4b' will allow NuGet to continue.

观测值

尝试在 dotnet Restore 中进行修复，但我收到了相同的错误。

dotnet sdk 2.0 没有这个问题。

Answer 1

就我而言，问题是由“锁定文件”的所有权（在 Linux 中）引起的。我在我的用户下运行dotnet build（没有 sudo），但我的项目是使用sudo.

选项 A） 再次使用 sudo

sudo dotnet build

选项 B） 更改 /tmp/NuGetScratch/lock/ 所有权：

sudo chown -R <user>:<user> /tmp/NuGetScratch/

然后，用户dotnet build无需 sudo 即可运行。

Answer 2

我用下面的命令修复了这个错误：

export TMPDIR=/tmp/NuGetScratch/
mkdir -p ${TMPDIR}

但是，我收到了其他错误，我打开了其他问题帖子：帖子
