检查你的错误日志中的最后一行：
`/Users/name/Development/Projects/movie_reviews/config/routes.rb:4: 语法错误，意外的输入结束，期望 'end' (SyntaxError)`
在你的 `routes.rb` 文件中某处缺少了一个 `end`（可能在第4行左右）。
你可以使用以下命令检查文件中是否存在语法错误：
`ruby -cw config/routes.rb`

Check the last line from your error log
/Users/name/Development/Projects/movie_reviews/config/routes.rb:4: syntax error, unexpected end-of-input, expecting `end' (SyntaxError)
You're missing an end somewhere in your `routes.rb` (possibly around line 4)
You can check if there is any syntax error on the file using
ruby -cw config/routes.rb
