使用 pyinstaller 创建 python windows 可执行文件时出现问题 - 创建、运行但立即退出

Question

I have the sample python code below. I create a windows executable app using PYINSTALLER. When it runs, it immediately quits. What should I be doing?

I also tried a basic (default) flask app - I get the same effect. I don't see any errors - just the window opens and closes immediately. I have searched all over for solutions - the stackoverflow ar Python script executable crashes immediately does not help. I am sure smart people have already solved this. Please help

import sys
import zerorpc


class Api(object):
    def echo(self, text):
        """echo any text"""
        return text


def main():
    addr = 'tcp://127.0.0.1:4242'
    s = zerorpc.Server(Api())
    s.bind(addr)
    print('start running on {}'.format(addr))
    s.run()


if __name__ == '__main__':
    main()

So, in my case - when I installed python (3.7.x), pyinstaller was installed with it. I assumed I could use this(now I know better). I did not install a separate pyinstaller in my virtual env - but I was using that to build the exe. This was the source of my problem - bcos, as soon as I did a pip install pyinstaller into my v.env - it worked!!! I am sure it is obvious to many of you who have been at python for a long time - not so for newcomers

I hope I help somebody who may run into this similar problem. We continue to learn
