我尝试分别安装gem和v8文件。我不知道该怎么办，因为我已经用尽了所有可能的选择

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

Gem files will remain installed in /Users/giowong/rails_project/doctible_pre_treatment/vendor/bundle/ruby/2.1.0/gems/therubyracer-0.12.1 for inspection.

An error occurred while installing therubyracer (0.12.1), and Bundler cannot

Make sure that `gem install therubyracer -v '0.12.1'` succeeds before bundling.
我正在使用brew安装ruby和rails，使用这个设置指南
https://gorails.com/setup/osx/10.10-yosemite
请帮忙，升级到Yosemite完全打乱了我的开发环境
也许这个问题与XCode最近的更新有关。XCode更新后，您需要执行以下步骤：
- 打开Xcode并接受许可协议
- 重新安装命令行工具
第二步似乎取决于您的操作系统版本。如果xcode-select --install不工作，请尝试在/System/Library/CoreServices中启动Install Command Line Developer Tools应用程序。
重新安装命令行工具后，请尝试重新运行bundle install。
试试这个对我有用：
gem install libv8 -- --with-system-v8
gem install therubyracer -v '0.12.1'
如果不起作用，尝试运行：
brew update
然后重试前两步。
我通过更改Gemfile 解决了同样的问题
gem 'therubyracer'
被取代
gem 'therubyracer', platforms: :ruby
你能试试这个吗？
这适用于Catalina
brew install v8@3.15
gem install libv8 -v 3.16.14.19 -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8@3.15
