Question

所以我要切换到使用ruby的项目。他们使用asdf作为包管理器

我在安装gem时遇到问题，我在使用zsh，并且认为路径可能有问题

运行gem install bundler输出：You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

ruby -v 输出：ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin18]

which ruby 输出：/usr/bin/ruby

我尝试使用asdf global ruby 2.5.3为ruby设置全局版本，但这似乎并没有改变版本

这是我的gem environment：

听起来您可能需要将相关行添加到.zshrc中，以便识别asdf垫片。您可以找到说明here

对于macOS和zsh，添加到.zshrc的正确行是：

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.zshrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.zshrc

这样做之后，source ~/.zshrc或重新启动您的终端

无法使用asdf安装gems
