通过自制软件安装特定版本的 R

Question

我已经在 macOS 中通过 Home-brew 安装了 R：

brew install R

不过现在，我需要切换版本并安装特定的 R 版本。出于这个原因，我尝试通过以下两种方式安装 R-3.5.2，但没有成功：

brew install R-3.5.2
brew install R@3.5.2

这是我得到的：

Error: No available formula with the name "r@3.5.2" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

你有什么想法吗？谢谢:)

免责声明：我没有 Mac 可用于测试。

Here you can find a quite useful tutorial on how to install old versions via homebrew, here是另一个。

对于 R 这意味着：

git clone https://github.com/Homebrew/homebrew-core.git
cd homebrew-core/
git log master -- Formula/r.rb

为 R 3.5.2 生成以下提交：

    r 3.5.2

    Closes #35321.

作为替代方案，您可以通过 URL 搜索提交（请参阅 this 评论）：

https://github.com/Homebrew/homebrew-core/search?q=r%203.5.2&type=commits

因此，您应该能够通过（最新的 R 3.5.2 提交）安装 R 3.5.2：

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/e66b3a288ee5e68c3c04e95705b7311c9f76bdf2/Formula/r.rb

或：

brew install https://github.com/Homebrew/homebrew-core/raw/e66b3a2/Formula/r.rb

brew switch 和 brew pin 中提到的 article 可能也很有趣。
