php – Google App Engine“解析./app.yaml时出错：未知的url处理程序类型”

我正在关注如何在Google App Engine上安装 PHPMyAdmin的教程,我完全按照指示操​​作,当我去推送应用程序时,我收到了解析错误.这是教程链接：
https://gae-php-tips.appspot.com/2013/05/26/setting-up-phpmyadmin-on-app-engine/

我搜索了Stackoverfllow并发现了一些同样错误的问题,几乎每个人都说他们是一个导致它的缩进问题,但我已经多次查看了我的文件,但是在app.yaml文件中没有找到任何缩进.

这是我的app.yaml文件

application: PHPmyadmin2121
version: PHPmyadmin
runtime: PHP
api_version: 1

handlers:
- url: /(.*\.(ico$|jpg$|png$|gif$))
static_files: PHPMyAdmin/\1
upload: PHPMyAdmin/(.*\.(ico$|jpg$|png$|gif$))
application_readable: true

- url: /(.*\.(htm$|html$|css$|js$))
static_files: PHPMyAdmin/\1
upload: PHPMyAdmin/(.*\.(htm$|html$|css$|js$))
application_readable: true

- url: /(.*\.(PHP$))
script: PHPMyAdmin/\1
secure: always
login: admin

- url: /(.+)
script: PHPMyAdmin/index.PHP
secure: always
login: admin

- url: /
script: PHPMyAdmin/index.PHP
secure: always
login: admin

以下是显示错误的命令行提示符：

Michaels-MacBook-Air：PHPMyAdmin Mike $appcfg.py -R -A PHPmyadmin2121 -V PHPmyadmin update.
用法：appcfg.py [options] update | [档案,……]
