Ruby kernel_gem.rb:67:in`synchronize'；：僵局递归锁定（线程错误）

在macOS Big Sur 11.2.3上运行此命令时：

pod setup

显示此错误：

$ pod setup                                                                                                                                                           ‹ruby-2.7.2›

现在我发现run

pod install

命令仍然显示此错误
