如何使用RVM在Mac OS上安装Ruby 2.4.0

我无法安装Ruby 2.4.0

• RVM版本为1.29.1
• Rubygems版本是2.6.11

我正在尝试使用以下方式安装Ruby 2.4.0：

rvm install ruby-2.4.0

我得到以下错误：

Searching for binary rubies, this might take some time.

认为您可能需要更新自制软件；请尝试

brew update

，然后重新尝试

rvm install ruby-2.4.0

命令

我本来会加上这句话作为评论的，但不够多。让我知道你进展如何

试过这个。。出现此错误：

错误：您对以下文件的本地更改将被合并覆盖：Library/Formula/libimobiledevice.rb请在合并之前提交或隐藏更改。中止错误：执行时失败：git pull-q origin refs/heads/master:refs/remotes/origin/master

检查此项。这可能会解决您的问题。就您的错误而言，您需要运行

git stash

，然后运行

brew update

，以便不覆盖任何文件
