我试图在我得到的旧Mac上升级Ruby版本，但没有任何成功。
我知道这是可能的，因为这个家伙在这里询问如何从 2.2 升级
这是我在终端中输入的内容：
rvm install 2.0.0
结果：
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.7/x86_64/ruby-2.0.0-p648.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Installing requirements for osx.
Updating system................
Installing required packages: coreutils.....There were package installation errors, make sure to read the log.
Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

Requirements installation failed with status: 1.
似乎缺少"coreutils"，所以我设法自己安装它，但没有成功：

此外，我还尝试按照此评论从源代码安装coreutils的步骤进行操作
wget https://ftpmirror.gnu.org/coreutils/coreutils-8.25.tar.xz
tar xJf coreutils-8.25.tar.xz
cd coreutils-8.25/
./configure --prefix=/usr/local
make
sudo make install
但是在那之后，出于同样的原因，重新安装Ruby 2.0.0再次失败。
有人可以帮我解决这个问题吗？
Homebrew不支持macOS 10.7。您可以使用Tigerbrew，这是Homebrew的一个分支，"增加了对PowerPC Mac的支持，以及运行Tiger或Leopard的Mac"(引用其主页(。
