（（这是我的第一篇文章，对不起，如果我出错了，]，
在Iterm2中，我输入：
rails _5.2.3_ new -d postgresql
终端会回答：
No value provided for required arguments 'app_path'
我打开.zshrc文件，试图找出问题是否出自此文件，并搜索了关键字PATH，但无法确定路径是否错误。问题是否在.zshrc文件上？问题在哪里，如何解决？
这是我的.zshrc文件

# Which plugins would you like to load?
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.

您没有为新项目指定名称。
尝试使用rails _5.2.3_ new NameOfTheApp -d postgresql
它应该工作。 （：
