解决VSCode中安装Go环境Gopls失败的问题

问题

# vscode报错
The "goimports" command is not available. Run "go install -v golang.org/x/tools/cmd/goimports@latest" to install.

# 终端输出
[error] gopls: failed to install gopls(golang.org/x/tools/gopls@latest): Error: Command failed: /usr/local/go/bin/go install -v golang.org/x/tools/gopls@latest
go: golang.org/x/tools/gopls@latest: invalid proxy URL missing scheme: direc
```

# 解决方法
在终端中运行以下命令：
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct
这将修改Go模块的代理设置，使用国内的代理服务器来获取Go模块。
