尝试在测试环境中运行 rails runner 时出现语法错误

Question

我创建了一个用 rails runner 运行的脚本。我在本地对其进行了测试，它工作得很好，但是在远程服务器上（它已部署到 AWS）它会引发以下错误：

/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

这里有完整的错误信息：

/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)

知道可能是什么问题吗？

你需要像这样执行命令：

rails runner script/content_update.rb

script/content_update.rb 是脚本的正确路径。

当您像/script/content_update.rb Rails 那样指定它时，在错误的位置搜索它却找不到它。当找不到文件时，Rails 将字符串视为Ruby 脚本并尝试执行它，然后引发这个奇怪的异常。
