Why does `python` points to my system's default python interpreter, instead of my `pyenv` pytho

python points to my system's default python interpreter, instead of my pyenv python interpreter.

I created the python virtual environment and activated it as follows:

pyenv virtualenv 3.8.12 test3
pyenv activate test3

Then, running python gives me a python 3.7 interpreter (which is my system's default python interpreter), instead of 3.8.12. Why?


Full command outputs:

root@server:/home/code-base/f# pyenv virtualenv 3.8.12 test3
Looking in links: /tmp/tmp1yp95sav
Requirement already satisfied: setuptools in /root/.pyenv/versions/3.8.12/envs/test3/lib/python3.8/site-packages (56.0.0)
Requirement already satisfied: pip in /root/.pyenv/versions/3.8.12/envs/test3/lib/python3.8/site-packages (21.1.1)

root@server:/home/code-base/f# pyenv activate test3
pyenv-virtualenv: prompt changing will be removed from future release. configure `export PYENV_VIRTUALENV_DISABLE_PROMPT=1' to simulate the behavior.

(test3) root@server:/home/code-base/f# python
Python 3.7.11 (default, Jul 27 2021, 14:32:16)
[GCC 7.5.0] :: Anaconda, Inc. on linux

Additionally:

  • pyenv which python returns /root/.pyenv/versions/test3/bin/python
  • command -v python returns /opt/conda/bin/python
  • $PATH: /root/.pyenv/plugins/pyenv-virtualenv/shims:/root/.pyenv/bin:/opt/conda/bin:/app/python/bin:/opt/conda/bin:/usr/local/mpi/bin:/usr/local/nvidia/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/.local/bin

CodePudding user response:

Two possible solutions here:

Either you did not select your 3.8.12 binary as a system default via:

$ pyenv global 3.8.12
$ python -V
Python 3.8.12

$ pyenv versions
  system
  2.7.15
* 3.8.12 (set by /home/realpython/.pyenv/version)

or /opt/conda/bin/ has a higher priority in your $PATH then your pyenv installation.

CodePudding user response:

  1. Install version of python you need.
pyenv install 3.8.12
  1. Activate it on your application directory
pyenv local 3.8.12
  1. Then locate python version
$ pyenv which python
/home/xirehat/.pyenv/versions/3.8.12/bin/python
