ruby-on-rails - 收到错误 "You' 我尝试在已经加载时调用 Spring“当我尝试启动服务器时

Question

当我尝试在我的本地计算机上运行“rails s”时，我开始收到以下错误:

You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).

This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

Here's the backtrace:

我的机器上安装了 Spring 2.1.0 版。我已经运行了错误消息询问的命令，bundle exec spring binstub --all 并且错误仍然存​​在。我阅读了另一个 SO 答案以尝试运行 bundle exec spring binstub --remove --all 确实删除了 binstubs，然后我再次运行第一个命令以重新生成它们。仍然出现相同的错误。

即使在其他 Rails 应用程序上，问题仍然存在。例如，当我在我的机器上切换到另一个应用程序并运行 rails s 时，我得到了同样的错误，即使我可能已经有几周没有使用该应用程序了。

问题是在安装 Docsplit 及其所需的依赖项以及 google-cloud-text_to_speech 之后出现的。可能值得注意的是，我的系统也不允许我卸载 google-cloud-text_to_speech gem。

我使用的是 MacOS 10.13.6

我设法解决了这个问题。当我删除 spring gem 并尝试启动我的 rails 服务器时，我收到以下消息:

/Users/emmetgibney/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require': dlopen(/Users/emmetgibney/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/pg-1.2.3/lib/pg_ext.bundle, 9): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib (LoadError)

这让我觉得这可能是 postgres 的问题，所以我使用 brew 卸载并重新安装了 postgres，这似乎已经解决了它。我现在可以为这个应用启动我的 Rails 服务器，也可以为我的所有其他应用启动 Rails 服务器。

自从很久以前安装 postgres 以来，我还没有涉及到它，所以我不知道 postgres 一开始是怎么搞砸的，但它现在仍然可以工作。
