I am using PyQt5 and freezing the app using pyinstaller. This app will create a QProcess to execute a service, which depends on my current virtual environment.

python 
self.p = QtCore.QProcess()
cmd = "-p 8888 -s dist/main/script/addons/meta_proxy.py -k"
params = shlex.split(cmd)
self.p.start("mitmproxy", params)

How can I run the QProcess from the Python environment that I am freezing? So that the users don't have to install anything to run their scripts other than my app.

Right now, after freezing, the QProcess uses the default Python2.7 environment installed on the machine.
