我认为我的bundle exec rails generate命令坏了（我有意义吗？）
当我生成某些东西时，我总是得到这个：
Traceback (most recent call last):

有人可以告诉我发生了什么以及如何解决这个问题吗？
干杯

首先尝试运行return tuple(car_df[car_df['sentiment'] == s]['count'].tolist() for s in ['positive', 'negative', 'neutral'])
或bundle。确保您还可以成功运行其他命令，例如bundle install，以检查它是否是一般配置问题（更可能是，如果出现＆＃34; 5.2＆＃34;此处出现错误）或特定问题产生

它看起来像你的运行rails版本5.1.6，但在你的加载文件中声明5.2。
通过将'load_defaults'更改为加载版本5.2而不是版本5.1（我当前的rails版本），我能够在测试应用中复制您的错误。相关行位于config / application.rb文件中。
config.load_defaults 5.2
有点难以进一步复制问题（只需将其更改回5.1即可为我删除错误消息），但rails api文档中有一些有关load_defaults的信息可能会有所帮助。
