我在这里遇到一个循环错误：
Bundler::GemspecError: Could not read gem at /path/to/website/vendor/cache/ruby/2.1.0/cache/libv8-3.16.14.7-x86_64-darwin-14.gem. It may be corrupted.
An error occurred while installing libv8 (3.16.14.7), and Bundler cannot continue.
Make sure that `gem install libv8 -v '3.16.14.7'` succeeds before bundling.
$ gem install libv8 -v '3.16.14.7'

Using koala (1.10.1)

有什么建议吗？
==== 更新
我尝试使用rm -rf ~/.rvm/gems/ruby-2.1.5/cache/删除所有缓存数据，现在bundle install --path vendor/cache给了我：
Bundler::GemspecError: Could not read gem at /path/to/website/vendor/cache/ruby/2.1.0/cache/libv8-3.16.14.7-x86_64-darwin-14.gem. It may be corrupted.

Make sure that `gem install libv8 -v '3.16.14.7'` succeeds before bundling.
对于 MacOS Catalina、Big Sur 和 Monterey：
brew install v8@3.15
bundle config build.libv8 --with-system-v8
bundle config build.therubyracer --with-v8-dir=$(brew --prefix v8@3.15)
bundle
（根据需要更新版本号）
面对同样的问题，使用系统偏好设置安装 gem 对我有用
gem install libv8 -v '3.16.14.7' -- --with-system-v8
通常的解决方案是将libv8更新到最新版本：
bundle update libv8
运行以下捆绑包配置命令，然后再次运行捆绑包
bundle config build.libv8 --with-system-v8
运行以下命令，然后再次运行捆绑包安装。
rm ~/.rvm/gems/ruby-2.1.2/cache/libv8-3.16.14.7-x86_64-linux.gem
