嘗試在測試環境中運行rails runner時出現語法錯誤

Question

我創建了一個腳本，以便與rails runner一起運行。我在本地測試，它工作得很好，但在遠程服務器上（它部署到AWS）它拋出以下錯誤：

/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 

完全錯誤的訊息：

/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，其中問題可能是？

你需要這樣的執行命令：

rails runner script/content_update.rb 

哪裏script/content_update.rb是你的腳本的正確路徑。

當您指定它爲/script/content_update.rbRails在錯誤的位置進行搜索並找不到它。當找不到該文件時，Rails將該字符串視爲Ruby腳本並嘗試執行它，然後引發此奇怪的異常。
