尝试在测试环境中运行 rails 运行器时出现语法错误

Question

我创建了一个与rails runner一起运行的脚本。我在本地对其进行了测试，它工作正常，但是在远程服务器(已部署到AWS(上，它抛出以下错误：

/home/ubuntu/my-project/vendor/bundle/ruby/2.1.0/gems/railties-4.1.14.1
/lib/rails/commands/runner.rb:62: 
syntax error, unexpected tIDENTIFIER, expecting end-of-input

完整的错误消息在这里：

/home/ubuntu/my-project/vendor/bundle/ruby/2.1.0/gems/railties-4.1.14.1/lib/rails/commands/runner.rb:62:in `eval': /home/ubuntu/my-project/vendor/bundle/ruby/2.1.0/gems/railties-4.1.14.1/lib/rails/commands/runner.rb:62: unknown regexp options - rt (SyntaxError)

知道问题可能是什么吗？

您需要像这样执行命令：

rails runner script/content_update.rb

其中script/content_update.rb是脚本的正确路径。

当您指定它时，/script/content_update.rbRails会在错误的位置搜索它并且找不到它。当找不到该文件时，Rails将字符串视为Ruby脚本并尝试执行它，然后引发此奇怪的异常。
