一开始百度看了很多博客，有说distribute没安装的，还有说pip版本没更新，尝试了之后还是不行，
最后想起来安装pyinstaller的时候因为网络原因pip不能用，选择了手动下载包安装，导致有pyinstaller需要的配置没有安装全

解决办法：重新pip安装pyinstaller；
如果还是网络太慢建议搭梯子；
或者换源

win+r,输入cmd打开终端
输入pip install pqi 后回车
成功后再次输入pqi ls 回车

再次输入pqi use aliyun（除了pypi都可以，aliyun只是举个例子）

换源后下载速度就高了
再次pip install pyinstaller完事儿
