推荐答案

使用sudo可能会解决您的问题，但是，当您安装gems时，将它们安装为sudo并不是一个好主意，因此首选方式在任何计算机上安装ruby的方法是先安装 rvm(Ruby版本管理器)，然后再安装您的ruby版本.

Being sudo might fix your problem, however when you are installing gems , its not a good idea to install them as sudo, so the preferred way of installing ruby on any machine is to install rvm (Ruby Version Manager) first and then install your ruby version.

拥有ruby版本管理器的主要优点是

Main advantages of having a ruby version manager are,

1-允许您并排安装多个红宝石版本

1 - allows you to install multiple ruby versions side by side

2-允许您为每个红宝石版本安装宝石(通过宝石集)

2 - allows you to install gems for each ruby version (via gemsets)

要在Mac中安装rvm，请在此处检查
