解决Pyinstaller打包软件失败的一个坑

最近写了一个软件屡屡打包不能正常运行，而直接在cmd命令行窗口运行却都能正常输出，没有任何报错，一开始怀疑程序里面sys.args[1]使用不对，找了很久发现import numpy才是导致代码不能打包的直接原因。

不知道为何引用这个包就不能正常打包成exe了。

程序编译中出错的代码如下

之前一直怀疑路径没处理对，后面看了很多别的代码发现也没问题，突发奇想是不是某个包造成不能正常压缩的，然后写了个测试文件，一行行注释掉引用的包后，发现只要注释掉了numpy便可以正常压缩成exe文件了。

补充：pyinstaller安装失败的解决办法

pyinstaller是一个很好用的将python文件打包成不依赖python环境的exe的库，但是在cmd中使用 “pip install pyinstaller”时，总会出现很多奇奇怪怪的问题。

我在安装库的过程中，碰到了下载之后，直接开始安装就报错退出安装的问题。

解决办法如下

1.其实一点也不麻烦

2.先“pip install pywin32”

3.在“pip install wheel”

4.试一下“pip install pyinstaller”

以上为个人经验，希望能给大家一个参考，也希望大家多多支持小牛知识库。如有错误或未考虑完全的地方，望不吝赐教。
