捆绑安装/ TheRubyRacer gem无法安装在MacOS Catalina 10.15.2上

Question

当尝试捆绑安装和安装therubyracer时，我已经厌倦了错误。我已经尝试了网络上的所有内容，但没有任何帮助。已经安装了libv8和x代码设置。感谢您的帮助！

命令sudo gem install therubyracer -v '0.12.3'之后，我收到错误消息：

    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

of V8 found on your system and *not* the one that is bundled with
the libv8 rubygem.

However, your system version of v8 could not be located.

Please make sure your system version of v8 that is compatible
with 3.16.14.19 installed. You may need to use the
--with-v8-dir option if it is installed in a non-standard location
    from /Library/Ruby/Gems/2.6.0/gems/libv8-3.16.14.19/lib/libv8.rb:7:in `configure_makefile'
    from extconf.rb:32:in `<main>'

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/therubyracer-0.12.3/mkmf.log

extconf failed, exit code 1 ```

Answer 1

我已经找到了解决此错误的方法。如果您对bundle install有疑问，请检查以下内容：

gem list libv8 --remote --all
gem install libv8 -v 3.16.14.19 -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/Users/YOUR_NAME/homebrew/opt/[email protected]

它为我工作，经过数小时的努力，我找到了所有解决方案。希望对别人有帮助。
