Python2.7 pyinstaller installation error: Command erred out with exit status 1

Error reporting reason:

Installing pyinstaller directly in python2.7 will report an error. Version 4 is incompatible with python2, so we need to specify a compatible pyinstaller version number during installation. The installation commands are as follows:

pip install pyinstaller==3.2.1

Py2exe installation command

pip install py2exe==0.6.9
