在Mac上通过RVM安装Ruby3.1时，正确的字符串是什么？

Question

我正在使用Mac，Big和rvm

$ rvm -v
rvm 1.29.12-next (master) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

我已经安装了版本2.7.5的Ruby，并且希望安装版本3.1。我试过了

$ rvm install 3.1
Unknown ruby string (do not know how to handle): ruby-3.1.

No fallback URL could be found, try increasing timeout with:

    echo "export rvm_max_time_flag=20" >> ~/.rvmrc

There has been an error fetching the ruby interpreter. Halting the installation.

当我访问URL https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.tar.gz时，我收到消息

<Error>
<Code>NoSuchKey</Code>

我从哪儿拿到钥匙的？rvm信息如下

$ rvm info

3.1似乎不在列表中，但是要安装它，您可以使用：

> rvm install ruby-3.1.0

或

> rvm install 3.1.0

但是，至少在rvm稳定的或最新的版本中，似乎是不可用的。看看GitHub，他们合并了补丁来添加3.1支持，但是最新的版本没有列出它：https://github.com/rvm/rvm/releases。

Answer 2

您现在可以用rvm get head安装RVM头。然后，rvm install 3.1将如预期的那样工作。
