为什么 Homebrew 找不到公式？ 修正搜索公式

问题描述

这里会发生什么？我一窍不通。 Homebrew 找不到brewsci/base/rstudio-server。它确实在那个水龙头上找到了其他公式。 rstudio-server.rb 脚本名称正确且位于正确的文件夹中。

我在 brewsci tap 中有两个公式。一个是boost-rstudio-server。 brew 找到了那个。它没有找到 rstudio-server，但它在同一个水龙头中。

me@iMac Formula $ brew install rstudio-server 

==> Searching for similarly named formulae...
These similarly named formulae were found:
brewsci/base/boost-rstudio-server ✔
brewsci/base/rstudio-server
lab/base/boost-rstudio-server-1.3 ✔
lab/base/drop-rstudio-server

Error: No available formula or cask with the name "rstudio-server".
==> Searching taps on GitHub...
Error: No formulae found in taps.

me@iMac Formula $ brew install brewsci/base/rstudio-server
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "brewsci/base/rstudio-server".

解决方法

这是由于tap中的语法问题

Error: Invalid formula: /usr/local/Homebrew/Library/Taps/brewsci/homebrew-base/Formula/rstudio-server.rb
rstudio-server: Calling depends_on :java is disabled! Use "depends_on "openjdk@11","depends_on "openjdk@8" or "depends_on "openjdk" instead.
Please report this issue to the brewsci/base tap (not Homebrew/brew or Homebrew/core),or even better,submit a PR to fix it:
  /usr/local/Homebrew/Library/Taps/brewsci/homebrew-base/Formula/rstudio-server.rb:36

Error: Cannot tap brewsci/base: invalid syntax in tap!

修正搜索公式

解决方法是手动签出水龙头

• mkdir -p /usr/local/Homebrew/Library/Taps/brewsci/homebrew-base
• cd /usr/local/Homebrew/Library/Taps/brewsci/homebrew-base
• git clone https://github.com/brewsci/homebrew-base .

然后你就可以找到公式了

$ brew search rstudio-server
==> Formulae
brewsci/base/boost-rstudio-server                     brewsci/base/rstudio-server

我没有 Linux 机器来测试实际安装，请告诉我 brew install 是否有效。
