我试图使用gem install mygem或使用gem update——system更新RubyGems安装一个gem,它失败了,错误如下:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
有人知道怎么解决这个问题吗?

你需要修正你的路径。
要确定此修复是否有效,请运行以下命令:
which gem
这应该会输出一个你没有权限的目录:
/usr/bin/gem
要修复此问题,请执行以下步骤:
Determine the path you need to copy to your profile: rbenv init - The first line of the output is the line you need to copy over to your profile: export PATH="/Users/justin/.rbenv/shims:${PATH}" #path that needs to be copied source "/usr/local/Cellar/rbenv/0.4.0/libexec/../completions/rbenv.zsh" rbenv rehash 2>/dev/null rbenv() { typeset command command="$1" if [ "$#" -gt 0 ]; then shift fi case "$command" in rehash|shell) eval `rbenv "sh-$command" "$@"`;; *) command rbenv "$command" "$@";; esac } Copy the path to your profile and save it. Reload your profile (source ~/.zshenv for me). Run rbenv rehash.
现在当你运行哪个gem时,你应该得到一个你有权限的本地路径:
/Users/justin/.rbenv/shims/gem
其他回答
为我工作:
sudo gem uninstall cocoapods
sudo gem install cocoapods
我需要做一个rbenv rehash,这样它就会指向我的本地Gem库。
看起来您已经让您的gem管理器指向系统库,因此,与其混淆权限,不如为您的管理器执行等效的“rehash”以获得指向本地的内容。

正如bobbdelsol所指出的,rehash对我来说很管用:

在MacOS Mojave上成功测试:
卸载所有旧的ruby版本(假设你有2.00和2.3.0): $ RVM卸载2.0.0 $ RVM卸载2.3.0 安装全新的ruby版本: 安装ruby 设置默认别名为您的版本: $ RVM别名创建默认ruby 重新启动您的系统,因为这是您的计算机加载最新安装的新ruby版本的最安全的方式。
完成以上步骤后,您可以成功地运行任何gem命令。
