当设置了GOPATH时,执行”go get $GOPATH”时出现错误。

英文:

Go : go get $GOPATH error, when GOPATH is set

问题

当运行go get命令时:

sudo go get github.com/go-sql-driver/mysql

我得到以下错误:

package github.com/go-sql-driver/mysql: 无法下载,$GOPATH未设置。有关详细信息,请参阅:go help gopath

然而,$GOPATH已经设置。

运行echo $GOPATH会得到/Users/userxyz/Desktop/Code

运行go env会得到

......

GOPATH="/Users/userxyz/Desktop/Code"

...

GOROOT="/usr/local/go"

.....

我已经尝试通过添加以下行将GOPATH设置为环境变量:

export GOPATH="$HOME/Desktop/Code"
export PATH=$PATH:$GOPATH/bin

分别添加到以下文件中:

~/.profile (/etc/profile)
~/.bashrc
~/.bash_profile

英文:

When running the go get command :

sudo go get github.com/go-sql-driver/mysql

I get the following error

> package github.com/go-sql-driver/mysql: cannot download, $GOPATH not
> set. For more details see: go help gopath

However $GOPATH is already set.

Running echo $GOPATH gives /Users/userxyz/Desktop/Code

Running go env gives

.....

GOPATH="/Users/userxyz/Desktop/Code"

...

GOROOT="/usr/local/go"

.....

I have already tried setting GOPATH as an environment variable by adding the following lines

export GOPATH="$HOME/Desktop/Code"
export PATH=$PATH:$GOPATH/bin

to the following files, alternatively

~/.profile (/etc/profile)
~/.bashrc
~/.bash_profile

sudo go get github.com/go-sql-driver/mysql

这个命令在root用户下运行go get,但是root用户没有设置$GOPATH

只需要执行以下命令:

go get github.com/go-sql-driver/mysql

通常,在项目文件夹中执行以下命令即可安装所有依赖项:

go get

以下命令将安装测试中提到的依赖项:

go get -t

英文:
sudo go get github.com/go-sql-driver/mysql

This runs go get under root user, which does not have $GOPATH set.

Just do:

go get github.com/go-sql-driver/mysql

Generally, do:

go get

in the project folder, and it will install all dependencies. The following will install dependencies mentioned in tests:

go get -t

你只需要去掉 sudo
你的环境变量是在用户级别定义的。如果你执行 sudo go env,你会发现 GOPATH 在那里没有设置。

英文:

You just need to drop the sudo.
Your environment variables are defined at the user level. if you do sudo go env you'll see that GOPATH is not set there

你不需要使用sudo。如果出现“同意Xcode/iOS许可证需要管理员权限”的提示,只需重新打开Xcode并接受Xcode的许可协议即可。

英文:

You don't need sudo. If the "Agreeing to the Xcode/iOS license requires admin privileges" stops you, just re-open Xcode and accept the license agreement of Xcode.

刚刚意识到写完回答后已经晚了将近4年,但我还是会保留回答,以防其他人可能需要这些答案...

看起来你可能是使用sudo或以root权限创建了该目录。如果你尝试使用普通用户运行$go get,你会得到一个权限错误,而如果你尝试使用sudo运行,你会得到一个GOPATH未设置的错误。我最近遇到了这个问题,并通过简单地更改目录的所有权来解决它。

export GOPATH=/your/goproject的目录
chown -R ubuntu@staff $GOPATH
cd $GOPATH && go get

这里是一些环境变量,你可以双重检查一下:

export GOPATH=/home/ubuntu/work
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

请记住,你不需要声明或更改$GOROOT。

最后,你可能想使用[profile.d][1]来导出环境变量:

cat > /etc/profile.d/setgoenv.sh <<EOL
export GOPATH=/home/ubuntu/work
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
EOL

希望对你有帮助。

Just realized after writing the response that it's almost 4 years too late but I'll leave it up just in case there are others who might need the answers...

So it seems like you might have created the directory with sudo or with root privileges. If you try $go get with a regular user you get a permissions error and when you try it with sudo you get a GOPATH unset error. I've had this problem recently, and I solved it by simply changing the ownership of the directory.

export GOPATH=/directory/of/your/goproject
chown -R ubuntu@staff $GOPATH
cd $GOPATH &amp;&amp; go get 

Here's just so you have some env variables to double check with:

export GOPATH=/home/ubuntu/work export
PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Keep in mind that there shouldn't be a need for you to declare or change $GOROOT.


Finally, you might want to use [profile.d][1] to export env variables:

cat &gt; /etc/profile.d/setgoenv.sh &lt;&lt;EOL
export GOPATH=/home/ubuntu/work
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
EOL

I hope that helped.

在我的情况下,我导入了一个不存在的错误的GOPATH和一个错误的GOROOT到我的PATH中。

设置export GOROOT=/opt/go然后export GOPATH=$HOME/work,确保$HOME/work存在并且我的用户有访问权限,似乎解决了go get {whattoget}的问题,然后确保export GOPATH=$HOME/work export PATH=$PATH:$GOROOT/bin:$GOPATH/bin在我的~/.profile中。这个帖子中没有任何内容完全适合。

未来,我可能会开始使用Docker来构建我的Go项目,因为这有点麻烦,文档和错误信息都很冗长,但似乎没有以有意义和清晰的方式解释出错的原因(GOROOTGOPATH都已设置,但PATHGOROOTGOPATH似乎都有点问题)。

英文:

In my case, I had imported an incorrect GOPATH that did not exist and an incorrect GOROOT in my PATH

setting my export GOROOT=/opt/go then export GOPATH=$HOME/work, ensuring $HOME/work existed and had access for my user seems to have solved the problem for go get {whattoget}, then ensuring export GOPATH=$HOME/work
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
was in my ~/.profile helped. Nothing in this thread seemed to quite fit.

Going forward I might just start using Docker to build my go projects, as it's a bit of a pain, and the documentation and errors are lengthy but don't seem to explain what is wrong in any meaningful and clear way (GOROOT and GOPATH were both setup, but PATH GOROOT and GOPATH all seemed to be a little off).
