Question

我似乎找不到这个具体的错误在这个网站上的任何地方的解决方案，希望有人能帮助。这是我在运行rails s时遇到的错误

➜  conquered_self git:(352_space_time_empires) ✗ rails s

Rails和Ruby版本：

➜  conquered_self git:(352_space_time_empires) ✗ ruby -v
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin21]
➜  conquered_self git:(352_space_time_empires) ✗ rails -v
Rails 5.0.7.2

顺便说一句，我尝试了前面提到的这里的建议，并将gem 'faraday-multipart'添加到我的then文件ran bundle中，然后rail s给了我一个不同的错误：

Answer 1

法拉第/法拉第-多部分：

如果您以前没有这些宝石，它们不是问题所在，您不需要添加它们。

$ gem uninstall faraday
$ gem uninstall faraday-multipart

此外，实际上没有安装(或者没有正确安装)，从堆栈跟踪的中间可以看到。尝试gem install faraday-multipart或者确保它在您的and文件中，然后运行bundle install (如果您真的想要的话)。还检查一下您的Gemfile.lock，看看faraday和faraday-multipart是否在那里。

，但，您似乎根本不需要法拉第或法拉第-多部分。所以你提到的是更新它们，而不是把它添加到一个没有它们的应用程序中。

三人：

这个问题来自于这颗宝石。具体来说，这个文件的第8行

您可以调试这个或升级这个严重过时的创业板。(你使用的是0.9.4，目前是0.16.16)

最好的解决办法：

因此，你的许多宝石看起来都是真的老旧过时了。包括Ruby和Rails。

如果我是您，我将首先将更新为3.1.2，然后将Rails gem更新为至少6.0+

接下来，我要么：

1. 仔细浏览Gemfile中的每个宝石，并在RubyGems上搜索并逐个升级宝石。
2. (蛮力方法)从Gemfile中删除所有版本要求，立即用bundle update升级每个gem，看看什么是固定的，什么是新损坏的。
