Golang的获取命令失败

Question

我使用此命令从GitHub下载软件包；但是输出令我惊讶，我想安装该软件包而不是在GOPATH或GOROOT下找到该软件包！

$ go get  github.com/golang/dep/cmd/dep

package github.com/golang/dep/cmd/dep: cannot find package "github.com/golang/dep/cmd/dep" in any of:
    /usr/local/Cellar/go/1.13/libexec/src/github.com/golang/dep/cmd/dep (from $GOROOT)
    /Users/mateuszhang/go/src/github.com/golang/dep/cmd/dep (from $GOPATH)

$ go get -u github.com/golang/dep/cmd/dep
package github.com/golang/dep/cmd/dep: cannot find package "github.com/golang/dep/cmd/dep" in any of:
    /usr/local/Cellar/go/1.13/libexec/src/github.com/golang/dep/cmd/dep (from $GOROOT)
    /Users/mateuszhang/go/src/github.com/golang/dep/cmd/dep (from $GOPATH)

您可能需要将环境变量$GO111MODULE设置为on。您可以通过在bash个人资料文件（即export GO111MODULE=on或〜/ .profile）末尾添加~/.bashrc来做到这一点。

是否要安装dep？运行：

go get -u github.com/golang/dep/cmd/dep

想从源代码安装吗？运行：

go get -d -u github.com/golang/dep
cd $(go env GOPATH)/src/github.com/golang/dep
DEP_LATEST=$(git describe --abbrev=0 --tags)
git checkout $DEP_LATEST
go install -ldflags="-X main.version=$DEP_LATEST" ./cmd/dep
git checkout master
