This application failed to start because no Qt platform plugin could be initialized. 报错解决方法

类似This application failed to start because no Qt platform plugin could be initialized

这种情况的报错，网络上会给出不同的解决方法，博主也一个一个地测试了一下，诸如修改环境变量等方式都没有解决这个问题，于是博主就开始怀疑是否是当自己在安装PyQt5的时候就根本没有安装成功呢？

于是，博主就重新安装了一下，使用到的命令如下

1 豆瓣：

1.1 PyQt5安装

pip install PyQt5 -i https://pypi.douban.com/simple

1.2 PyQt5-tools安装

pip install PyQt5-tools -i https://pypi.douban.com/simple

2 官网：

2.1 PyQt5安装

pip install PyQt5

2.2 PyQt5-tools安装

pip install PyQt5-tools

简单测试一下，能够运行并且弹出窗口，如下

当然，不同的人的问题情况也是不一样的，还是需要多去查阅资料，学会自己解决问题
