在EC-CUBE站点中安装和卸载插件

When I uninstall my plugin I got bellow warning:

gen -> C:\Users\lttan\AppData\Local\Temp/proxy_Vt9ThzogNEXt/Product.php

In MappingDriverChain.php line 106:

Warning: Invalid argument supplied for foreach()

eccube:plugin:uninstall [--code [CODE]] [--uninstall-force [UNINSTALL-FORCE]] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-
ansi] [-n|--no-interaction] [-e|--env ENV] [--no-debug] [--]

But the plugin still has been uninstalled. But then I can't install another plugin to my site.
