Bash-终端错误：“-bash：导出：`GOPATH〜/ usr / go'：无效的标识符”

I am currently learning the Go programming language. And I followed a sequence of video tutorials on youtube for installation.

I inputted this line in the terminal:

echo "export GOPATH~/Users/Guest/Documents/go" >> .bash_profile

And when I opened the terminal again, below error is displayed at the top:

-bash: export: `GOPATH~/Users/Guest/Documents/go': not a valid identifier

Is there a way on how to fix/remove the error?

There's a typo in the command. Edit .bash_profile and change the command to:

export GOPATH=/Users/Guest/Documents/go
