WSL2 Golang安装工具:权限被拒绝

Question

我正在尝试在WSL2/Ubuntu中安装golang工具，以便在VSCode中使用它们。每次我想要通过VSCode安装它们时，我都会收到权限被拒绝的消息：

我的主要操作系统是Windows10，我使用VSCode1.49.2结合WSL2和Ubuntu20.04。Go版本是go1.15.2 linux/amd64。需要什么权限才能更改？

Answer 1

我刚刚升级到WSL2 (在Windows10上使用Ubuntu20.04)，并找到了你的问题，因为我正在绞尽脑汁试图弄清楚为什么我不能运行一个简单的sam构建而不得到权限错误。我发现它是/etc/wsl.conf中配置的权限的一部分。

基于我看到的一个vscode问题，我将wsl.conf文件设置为以下设置：

[automount]
enabled=true
root = /
options="metadata,uid=1000,gid=1000,umask=002,dmask=002,fmask=002"

这些选项将文件的所有者设置为使用uid=1000的用户和使用gid=1000而不是根用户的组。这应该是您登录时所使用的管理员用户，这样您就不必克服所有文件的root所有权。umask、dmask和fmask设置新创建文件的文件权限掩码，basic设置新文件和目录的读/写权限，因此您可以再次安装文件。

我不确定这是否是你遇到的问题，但它看起来非常相似，我花了一个非常困难的周末试图弄清楚它，所以我想把它传递给大家！
