Rails 5服务器问题（Windows 10）

Question

这里是Ruby on Rails的新手，我刚刚在Windows 10（Bash on Ubuntu shell）上安装了Ruby & Rails。我似乎在启动Rails服务器时遇到了问题。已经在该问题上检查了其他线程，但其他人都在使用OSX。 :(希望有人能帮助

在运行时轨道S，

root@TEAMROCKETHQ:~/newapp# rails s 
/root/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/railties-5.0.2/lib/rails/app_loader.rb:40: warning: Insecure world writable dir /root/.rbenv/versions in PATH, mode 040777

对于第一线的问题，我想：

sudo chmod 775 /usr/local 

似乎并没有做任何事情，也许我。 “M读取错误错了，但我不知道......当我去到本地主机：3000，它返回此错误：

Answer 1

这是因为puma 3.8.0。

将gem 'puma', '3.7.1'放入您的gem文件中，然后再放入bundle install。

和gem uninstall puma在版本3.8.0，等到有修复。
