乘客：启动预加载器时出错

Posted 2023-03-04

【中文标题】乘客：启动预加载器时出错

【英文标题】：Passenger: An error occurred while starting up the preloader

【发布时间】：2013-09-21 00:39:24

【问题描述】：

我已经尝试过这里推荐的内容：Passenger: internal server error，但在 config.ru 中没有发现对 STDOUT 的引用

我正在使用 ruby​​-2.0.0-p247 和乘客 (4.0.17)

尝试加载页面后的控制台输出：

【参考方案1】：

对我来说，它有效

cd <usr name>
rails new myapp 
sudo bundle install 
mkdir /home/<user name>/myapp
chmod 701 /home/myapp
chmod -R 705 /home/<user name>/myapp
chgrp -R www-data /home/<user_name>/myapp
chown -R <user_name> /home/<user_name>
