我在尝试运行＆＃34; rails server＆＃34;时遇到错误，我正在遵循以下建议：https://www.youtube.com/watch?v=GwaeRJRoCeo

这就是我得到的：

我试着改变 在config / environments / development.rb中：

firstapp::Application.configure do 

仍有错误

Answer 1

上次，我遇到了和你一样的问题。你可以这样做来解决它。

gem uninstall rmagick 
gem cleanup 
bundle install

它对我有用。你可以尝试一下。

Answer 2

我得到了答案，在Windows中，我可以在3000端口运行 现在我尝试使用它：

rails server -p 80

它的工作
