Can't understand easily what's wrong here, would you be available for some remote debugging in the following days? 😃 |
|
Unfortunately, for the next week or so it'll be difficult to schedule a time (but thanks :)). What I have been able to find out so far is the following:
|
|
Wait what you're describing is that nox is running with the python 3.8 binary, but links to 3.7.6 on system level. We have a section describing this within our readme, see the warning, https://virtualenv.pypa.io/en/latest/user_guide.html#python-discovery. we'll always use the system executable when you pass a python path, not the underlying pythons path. How did pipx created a python 3.8 env that references 3.7.6? |
|
I'm not sure I understand. Nox is not running with a Python 3.8 binary. Nox (and pipx) are running under Python 3.7.6 from Homebrew:
The path in the shebang ( The Python interpreter in Nox's virtualenv ( This is also the Python interpreter used by Nox when invoking virtualenv. So Python 3.8 should only come into play when virtualenv searches the PATH. |
|
I guess the error here comes why does the python 3.8 shim says the system executable is noxs. We will need to debug the system executable detection algorithm within py info to find the answer. If you have some time throw a debugger at it and see what goes wrong, you may call py info file directly for this. |
|
Everything works just fine if I install Nox with pip instead of pipx, by the way. |
|
Ok will try this. |
|
When run on its own, the py_info script produces the expected result: $ /Users/cjolowicz/.pyenv/shims/python3.8 -s /Users/cjolowicz/.local/pipx/venvs/nox/lib/python3.7/site-packages/virtualenv/discovery/py_info.py|grep system_executable
"system_executable": "/Users/cjolowicz/.pyenv/versions/3.8.1/bin/python3.8",But when run as a subprocess from virtualenv, we get the wrong system_executable: $ ~/.local/pipx/venvs/nox/bin/python -m virtualenv /tmp/venv -p python3.8
$ grep system_executable ~/Library/Application\ Support/virtualenv/py-info/20.0.4/899ac50ce9bd2b17f79c71bdfa3e3c53264c3169cd7266b4352c162e4813ab33.json
"system_executable": "/Users/cjolowicz/.local/pipx/venvs/nox/bin/python",For some strange reason, in the subprocess running virtualenv/src/virtualenv/discovery/py_info.py Lines 100 to 103 in 5b88149 Details: output of some debug statements I added to virtualenv. Using PDB was tricky as the interesting stuff happens in the subprocess, and PDB seemed to break the communication between parent and child. |
|
If I read the code correctly, virtualenv/src/virtualenv/discovery/py_info.py Lines 94 to 107 in 5b88149 virtualenv/src/virtualenv/discovery/py_info.py Lines 284 to 294 in 5b88149 virtualenv/src/virtualenv/discovery/py_info.py Lines 309 to 326 in 5b88149 Unfortunately, Here is an example session: # Python 3.8 (from pyenv) reports itself.
$ /Users/cjolowicz/.pyenv/shims/python3.8 -c "import sys; print(sys._base_executable)"
/Users/cjolowicz/.pyenv/versions/3.8.1/bin/python3.8
# Python 3.7 (from Homebrew inside pipx env) reports itself.
$ /Users/cjolowicz/.local/pipx/venvs/nox/bin/python -c "import sys; print(sys._base_executable)"
/Users/cjolowicz/.local/pipx/venvs/nox/bin/python
# Python 3.8 (pyenv) as subprocess of Python 3.7 (Homebrew/pipx) reports the interpreter in the parent process.
$ /Users/cjolowicz/.local/pipx/venvs/nox/bin/python -c 'import subprocess; subprocess.run(["/Users/cjolowicz/.pyenv/shims/python3.8", "-c", "import sys; print(sys._base_executable)"])'
/Users/cjolowicz/.local/pipx/venvs/nox/bin/pythonSo if Nox was installed with pipx, and is therefore running from a virtual environment, every Python interpreter will be identified the same as the system version (or rather, the version pipx was installed with), no matter its actual version. |
|
I guess there was still a missing link in the reasoning above. Why does virtualenv think that the pyenv shim is run from inside a virtual environment? Only then would the logic with The virtual environment is detected by comparing # sys.prefix in the subprocess comes from the parent.
$ /Users/cjolowicz/.local/pipx/venvs/nox/bin/python -c 'import subprocess; subprocess.run(["/Users/cjolowicz/.pyenv/shims/python3.8", "-c", "import sys; print(sys.prefix)"])'
/Users/cjolowicz/.local/pipx/venvs/nox
# sys.base_prefix in the subprocess comes from the child.
$ /Users/cjolowicz/.local/pipx/venvs/nox/bin/python -c 'import subprocess; subprocess.run(["/Users/cjolowicz/.pyenv/shims/python3.8", "-c", "import sys; print(sys.base_prefix)"])'
/Users/cjolowicz/.pyenv/versions/3.8.1So virtualenv assumes that the pyenv shim is run from a virtual environment, and uses |

Hello, a fix for this issue has been released via virtualenv 20.0.5; see https://pypi.org/project/virtualenv/20.0.5/ (https://virtualenv.pypa.io/en/latest/changelog.html#v20-0-5-2020-02-21) . Please give a try and report back if your issue has not been addressed; if not, please comment here, and we'll reopen the ticket. We want to apologize for the inconvenience this has caused you and say thanks for having patience while we resolve the unexpected bugs with this new major release. |

@Pithikos for now you can work around the issue by installing https://packages.ubuntu.com/bionic/python3.6-distutils, however we should still operate under this behaviour for that created #1910, please feel free to submit a PR to fix it if you have time. |
