安装“gem”时出错，Bundler 无法继续。 Mac OS - 大软件

Question

我之前在升级到 Catalina 时使用 nio4r gem 发生了这个错误，@dmitry barskov 回答了它。在使用 json、oj 和 therubyracer 进行大 sur 升级后，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。

当我进行捆绑更新时，它会卡在解决依赖关系中……我让它运行了 12 个小时才放弃。 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...。

我正在使用 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。

Answer 1

我最终删除了项目文件夹并克隆了一个新文件夹。像@taylorthurlow 指出的那样，删除了所有 gem，重新安装了 rbenv。

一切正常，捆绑安装是绿色的。
