Puma抱怨找不到/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）没有该文件的权限。

检查文件是否存在以及是否正确设置了权限。如果文件不存在，你可以在Unix系统上做这样的事情来创建路径中的文件夹和一个空白文件：

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

这将确保正确创建文件。执行此操作后，请务必再次验证文件权限。
