VSCODE无法在go模块中安装工具

Question

在VSCode上启动go模块时，系统提示我安装一些工具

在vscode终端中的日志下方，选择安装安装失败

VSCODE一直对我大喊“无法安装”的东西，仅仅是因为忽略了我的路径 如下所示

Tools environment: GOPATH=/home/go
Installing 1 tool at /home/go/bin in module mode.
  gopls

Installing golang.org/x/tools/gopls FAILED

1 tools failed to install.

gopls: failed to install gopls(golang.org/x/tools/gopls): Error: Command failed: /usr/local/go/bin/go get -v golang.org/x/tools/gopls
go: writing stat cache: mkdir /home/go: permission denied
go: downloading golang.org/x/tools/gopls v0.5.1
go: downloading golang.org/x/tools v0.0.0-20201017001424-6003fad69a88
go get golang.org/x/tools/gopls: mkdir /home/go: permission denied
 undefined  

这些是我的GOPATH和GOROOT

# GOLANG
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$PATH
export PATH=$GOROOT/bin:$PATH

这是我的vscode settings.json

{
    "[dart]": {
        "editor.formatOnSave": true,
        "editor.formatOnType": true,
        "editor.rulers": [
            80
        ],
        "editor.selectionHighlight": false,
        "editor.suggest.snippetsPreventQuickSuggestions": false,
        "editor.suggestSelection": "first",
        "editor.tabCompletion": "onlySnippets",
        "editor.wordBasedSuggestions": false
    },
    "workbench.iconTheme": "material-icon-theme",
    "workbench.colorTheme": "One Dark Pro",
    "dart.sdkPath": "/home/francesco/development/dart",
    "dart.openDevTools": "flutter",
    "go.formatTool": "goimports",
    "dart.checkForSdkUpdates": false,
    "go.useLanguageServer": true,
    "go.inferGopath": false,
    "go.gopath": "/home/go",
    "go.goroot": "/usr/local/go"
}

我应该采取什么措施来纠正错误？

Answer 1

您的错误是：

go: writing stat cache: mkdir /home/go: permission denied

Go尝试写入/home/go。此文件夹源自：

export GOPATH=$HOME/go

因此，看来您的$HOME没有指向您的主文件夹。 GOPATH应该指向您具有写许可权的文件夹，因为模块缓存位于GOPATH下。因此，它应指向用户主目录下的文件夹，例如/home/francesco/go。
