环境

$ go version
go version go1.15.2 linux/amd64

我想要什么

我想做一个用 Go 实现的微服务。

发生了什么

当我运行 git commit 时，预先提交运行 golint 命令，现在它会打印 'golint: command not found'。

我想知道的

为什么 golint 不能运行？如何解决？

【解决方案1】：

您需要获取并保留对 PATH 环境变量的更改。如果您使用 bash，您可以将下一个更改添加到 .bashrc 或 .bash_profile（取决于操作系统）。

export GOPATH="${HOME}/go"
export GOROOT="/usr/local/opt/go/libexec"

if [[ $PATH != *$GOPATH* ]]; then
    export PATH="${GOPATH}/bin:${PATH}"
fi

if [[ $PATH != *$GOROOT* ]]; then
    export PATH="${GOROOT}/bin:${PATH}"
fi

注意：在我的例子中，有 $HOME 变量，但你可以写你的 gopath 的完整路径。
