抱怨没有找到'/ Users/Paradise/Documents/Dev/salon-spa-pass/AdminInterface/shared/log/puma.stdout.log'。在unix/linux/Mac OS X系统上，这可能意味着进程（或其用户）无权访问该文件。检查文件是否存在以及权限是否设置正确。 –

我可以只添加共享文件夹，日志文件夹和空白puma.stdout.log文件吗？ –

@MichaelGaskill添加文件夹和日志文件的工作！谢谢。你可以添加这个作为你的答案，我会upvote它。 –

彪马抱怨/Users/Paradise/Documents/Dev/salon-spa-pass/AdminInterface/shared/log/puma.std‌out.log没有找到。在unix/linux/Mac OS X系统上，这可能意味着进程（或其用户）无权访问该文件。

检查文件是否存在以及权限设置是否正确。如果该文件不存在，你可以做这样的事情在Unix系统上创建路径和一个空文件夹：

mkdir -p /Users/Paradise/Documents/Dev/salon-spa-pass/AdminInterface/shared/log/ && touch /Users/Paradise/Documents/Dev/salon-spa-pass/AdminInterface/shared/log/puma.std‌out.log

这将确保该文件被正确创建。执行此操作后，请务必再次验证您的文件权限。
