  84. # 答案1
  85. **得分**: 2
  86. 检查你的错误日志中的最后一行：
  87. `/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)`
  88. 在你的 `routes.rb` 文件中某处缺少了一个 `end`（可能在第4行左右）。
  89. 你可以使用以下命令检查文件中是否存在语法错误：
  90. `ruby -cw config/routes.rb`
  91. <details>
  92. <summary>英文:</summary>
  93. Check the last line from your error log
  94. /Users/name/Development/Projects/movie_reviews/config/routes.rb:4: syntax error, unexpected end-of-input, expecting `end&#39; (SyntaxError)
  95. You&#39;re missing an end somewhere in your `routes.rb` (possibly around line 4)
  96. You can check if there is any syntax error on the file using
  97. ruby -cw config/routes.rb
  98. </details>
