问题描述
当我升级到 Catalina 时，这个错误发生在我之前的 nio4r gem 上，@dmitry barkov 回答了这个错误。在使用 json、oj 和 therubyracer 进行大 sur 升级之后，现在发生了类似的问题（尝试使用 nio4r 的解决方案，但没有运气）。当我运行 gem list 时，我看到 gems 已安装但捆绑安装失败。所以我尝试了 bundle update json oj therubyracer。它适用于 json 和 oj 但对于 therubyracer，它会引发错误。
therubyracer 错误 -->

gem uninstall -a libv8

gem install libv8 -v '3.16.14.17' — —with-system-v8
gem uninstall -a therubyracer
bundle config build.libv8 --with-system-v8
gem install therubyracer -v '0.12.2' -- --with-v8-dir=$(brew --prefix v8@3.15)
当我执行 bundle update 时，它在解决依赖项时卡住了……我让它运行了 12 个小时，然后我放弃了。 当我删除我的 gemfile.lock 并运行 bundle install 时，它再次陷入解决依赖关系的问题......
我使用的是 ruby v 2.3.1 捆绑器版本 1.17.3
我注意到的一件事是路径 /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby 显示 2.6.0，但我使用的是 2.3.1（通过运行 rbenv local 和 ruby -v 确认）
如果需要任何其他信息，请告诉我。任何帮助将不胜感激。
解决方法
我最终删除了项目文件夹并克隆了一个新文件夹。删除了所有宝石，重新安装了 rbenv，就像@taylorthurlow 指出的那样。
一切顺利，捆绑安装是绿色的。
