There is a problem with pyinstaller
Environment:
win10 64-bit operating system
python 3.7.3
Use pip to install pyinstaller, which is successful, and pywin32 will also be installed. But no matter how to transfer exe, a lot of errors occurred.
Later, download the Development version on the pyinstaller official website ( https://github.com/pyinstaller/pyinstaller/zipball/develop), unzip it, enter the directory, and install it with the following command:
python setup.py install
Then transfer the exe to success. It went well without a single error.
