1.错误描述

使用如下方式安装beego的时候出错

go get github.com/astaxie/beego

错误信息:

go install unicode/utf8: open /opt/go/pkg/linux_amd64/unicode/utf8.a: permission denied
go install unicode: open /opt/go/pkg/linux_amd64/unicode.a: permission denied
go install math: open /opt/go/pkg/linux_amd64/math.a: permission denied
go install sort: open /opt/go/pkg/linux_amd64/sort.a: permission denied
go install hash: open /opt/go/pkg/linux_amd64/hash.a: permission denied
go install unicode/utf16: open /opt/go/pkg/linux_amd64/unicode/utf16.a: permission denied
go install crypto/subtle: open /opt/go/pkg/linux_amd64/crypto/subtle.a: permission denied
go install container/list: open /opt/go/pkg/linux_amd64/container/list.a: permission denied
go install internal/syscall: open /opt/go/pkg/linux_amd64/internal/syscall.a: permission denied
go install time: open /opt/go/pkg/linux_amd64/time.a: permission denied

然后我在命令前加了一个sudo,然后提示

go: cannot find GOROOT directory: /usr/local/go

2.解决办法

go install unicode/utf8: open /opt/go/pkg/linux_amd64/unicode/utf8.a: permission denied

出现这样的错误原因是，当初我是直接将golang的压缩包拷到了/opt目录下，所有的源代码都未经编译，应该先切换到/opt/go/src目录下，执行sudo ./make.bash脚本编译，完成后在使用如下命令安装beego就不会出错了：

go get github.com/astaxie/beego

这样的话，在执行如下命令安装bee工具的时候会提示权限不够：

go get github.com/beego/bee

go install github.com/beego/bee: open /opt/go/bin/bee: permission denied

对此我的解决办法是先切换到/opt目录，执行如下命令，修改go文件夹的权限：

sudo chmod -R 777 go/

这样就能正常安装bee工具了。
