Answer 1

您可以尝试通过ruby安装rbenv，如本教程所示：

我尝试过并取得了成功。

install rbenv on osx

更新

您应该执行以下步骤：

brew install rbenv
brew install ruby-build
echo 'export RBENV_ROOT=/usr/local/var/rbenv' >> ~/.bash_profile
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile

然后你用rbenv来安装ruby。首先，找到所需的版本：

rbenv install -l

rbenv install 2.3.1

Answer 2

我找到了

https://www.ruby-lang.org/en/documentation/installation/

搜索关键词“从源头构建”

按照说明操作下载 - ＆gt;解压缩 - ＆gt;终端cd到文件夹 - ＆gt;明星打出这三行称赞。

如果安装其他需要红宝石的话。您可能仍需要输入$。/ configure --with-openssl-dir = / usr / local / ssl
