osx下安装revel无权限，$GOPATH not set

##osx下安装revel无权限，$GOPATH not set

  1. 执行go get github.com/revel/revel错误，提示无权限
  2. 根据提示执行sudo go get github.com/revel/revel错误，提示没有$GOPATH not set
  3. 然而已经在~/.bash_profile中设置了$GOPATH
localhost:golang yeshu$ go get github.com/revel/revel
# cd .; git clone https://github.com/revel/revel /Users/yeshu/code/golang/src/github.com/revel/revel
Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.
package github.com/revel/revel: exit status 69

localhost:golang yeshu$ sudo go get github.com/revel/revel
Password:
package github.com/revel/revel: cannot download, $GOPATH not set. For more details see: go help gopath

localhost:golang yeshu$ echo $GOPATH
/Users/yeshu/code/golang

还是老外的回答最好

  1. 第一个无权限错误原因：You don’t have write access to your GOPATH. Typically you would set GOPATH=~/gocode or something
  2. 第二个提示$GOPATH没设置原因：new environment is created when you “sudo” – the root user does not have the GOPATH set. (Also, you probably don’t want to solve it in this way anyway)

##这里不是GOPATH目录没有写权限问题
Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

因为系统自动更新了xcode，所以需要打开xcode同意下新的条款。（mb，xcode更新管我什么事情）

解决方案：

  • 命令行执行sudo xcodebuild -license同意条款
  • 打开xcode同意一下
