There was an error while trying to write to Gemfile.lock. It is likely that you need to allow write permissions for the file at path: /var/www/PCMI/zil/Gemfile.lock (Bundler::InstallError)

推荐答案

似乎乘客无法写入您的 gem 文件的锁定文件.基本上它不能确定您没有捆绑运行，因为它无法获得对该文件的排他锁.

It looks like passenger can't write to the lock file for your gem file. Basically it can't be sure your not running bundled because it can't get an exclusive lock on that file.

确保用户乘客在(apache 默认为 www-data)下运行对该文件具有写权限.

Make sure the user passenger is running under (apache defaults to www-data) has write permission on that file.

你可以使用 chown 和 chmod
