安装“jekyll”后无法使用“vagrant”，错误为“找不到 gem vagrant”

安装后和gem install jekyll我的命令失败，显示：

$ vagrant up

我需要一个临时的解决方法（变量在中声明~/.bashrc）：

$ unset GEM_HOME GEM_PATH

现在，我可以运行了vagrant。有什么明确的解决方案可以避免此类问题？

答案1

解决方案是删除

export GEM_PATH=$HOME/gems # to remove

这已经足够了：

export GEM_HOME="$HOME/gems"
export PATH=PATH=~/gems/bin:$PATH
