尝试在测试环境中运行rails runner时出现语法错误

Question

我创建了一个脚本，以便与rails runner一起运行。我在本地测试，它工作得很好，但在远程服务器上（它部署到AWS）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 

完全错误的讯息：

/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)

    from bin/rails:4:in `<main>' 

任何想法，其中问题可能是？

你需要这样的执行命令：

rails runner script/content_update.rb 

哪里script/content_update.rb是你的脚本的正确路径。

当您指定它为/script/content_update.rbRails在错误的位置进行搜索并找不到它。当找不到该文件时，Rails将该字符串视为Ruby脚本并尝试执行它，然后引发此奇怪的异常。
