#2112 How to specify a python interpreter in a virtualenv on the run using PEX_PYTHON？ New discussion created by zeyuwang615 Hi, there! I am trying to run a packed python .pex file with the command

./xxx.pex main.py

. However, I just discover that there are a few necessary packages missing in the pex file. So I try to specify the custom python interpreter in a virtualenv with all the necessary packages with the

PEX_PYTHON

environment variable. Strangely,

PEX_PYTHON=/path/to/venv/python ./xxx.pex main.py

does not work, and so does

/path/to/venv/python ./xxx.pex main.py

. I wonder how I can specify the python environment or add the necessary packages without needing to regenerate or change the .pex file? Thanks a lot! pantsbuild/pex
