发现问题

(python3.7) D:\Desktop\文件夹\Oriental_Fortune_Hot_Post\newwork\data\000725-002045>pyinstaller -F OFHP.py
Fatal error in launcher: Unable to create process using '"e:\anaconda3\envs\tf2.0\python.exe"  "E:\Anaconda3\envs\python3.7\Scripts\pyinstaller.exe" -F OFHP.py': ???????????

报错原因

这里报错说的是两个虚拟环境tf2.0和python3.7冲突的问题。
博主之前将自己的一个虚拟环境tf2.0改成了python3.7，但是在装pyinstaller包的时候环境名称还是tf2.0，所以我想应该是更改虚拟环境名称的问题，所以最简单的方法就是把这个包删掉重装，结果果然成功了！
