Issue

I'm trying to do some Python development on an Android phone. I pkg install python pipx, I pipx install tox, and when I run tox, I get this traceback from inside virtualenv's Python interpreter discovery code:

(I originally filed this as a tox bug, but, well, the crashing code is virtualenv's.

Environment

Provide at least:

Output of the virtual environment creation

This is difficult, as when I run virtualenv myself, it works fine. When pipx runs virtualenv, it works fine. When tox runs virtualenv, it crashes -- and I've no idea how to ask tox to please run virtualenv with -vvv --with-traceback.

Well, there is a traceback at least. And the cause is pretty obvious: my $PATH contains a directory that is not accessible to the user running virtualenv.

My $PATH is

$ echo $PATH | tr : '\n'
/data/data/com.termux/files/home/bin
/data/data/com.termux/files/home/bin/local
/data/data/com.termux/files/home/.local/bin
/usr/games
/usr/local/sbin
/usr/local/bin
/usr/sbin
/sbin
/data/data/com.termux/files/usr/bin
/product/bin
/apex/com.android.runtime/bin
/apex/com.android.art/bin
/system_ext/bin
/system/bin
/system/xbin
/odm/bin
/vendor/bin
/vendor/xbin
$ ls -ld /system_ext/bin
drwxr-x--x. 3 root shell 4096 Jan  1  2009 /system_ext/bin

I have no idea why Termux puts an inaccessible directory on the default PATH, but it would be helpful if virtualenv's interpreter discovery would skip it instead of failing entirely.

(I have another Android device - a Nokia N20 tablet with Android 13. Tox and virtualenv work fine on it in Termux 0.118.0. The default $PATH is shorter and doesn't mention /system_ext)

Run tox with -vvvv 👍

tox -vvvv:

Issue

I'm trying to do some Python development on an Android phone. I pkg install python pipx, I pipx install tox, and when I run tox, I get this traceback from inside virtualenv's Python interpreter discovery code:

(I originally filed this as a tox bug, but, well, the crashing code is virtualenv's.

Environment

Provide at least:

  • OS: Android 14, Termux version "googleplay.2024.10.30".
  • pip list of the host python where virtualenv is installed:

$ pipx runpip tox list Package Version

cachetools 5.5.0 chardet 5.2.0 colorama 0.4.6 distlib 0.3.9 filelock 3.16.1 packaging 24.1 pip 24.3.1 platformdirs 4.3.6 pluggy 1.5.0 pyproject-api 1.8.0 tox 4.23.2 virtualenv 20.27.


**Output of the virtual environment creation**

This is difficult, as when I run virtualenv myself, it works fine.  When pipx runs virtualenv, it works fine.  When *tox* runs virtualenv, it crashes -- and I've no idea how to ask tox to please run virtualenv with `-vvv --with-traceback`.

Well, there is a traceback at least.  And the cause is pretty obvious: my $PATH contains a directory that is not accessible to the user running virtualenv.

My $PATH is

```console
$ echo $PATH | tr : '\n'
/data/data/com.termux/files/home/bin
/data/data/com.termux/files/home/bin/local
/data/data/com.termux/files/home/.local/bin
/usr/games
/usr/local/sbin
/usr/local/bin
/usr/sbin
/sbin
/data/data/com.termux/files/usr/bin
/product/bin
/apex/com.android.runtime/bin
/apex/com.android.art/bin
/system_ext/bin
/system/bin
/system/xbin
/odm/bin
/vendor/bin
/vendor/xbin
$ ls -ld /system_ext/bin
drwxr-x--x. 3 root shell 4096 Jan  1  2009 /system_ext/bin

I have no idea why Termux puts an inaccessible directory on the default PATH, but it would be helpful if virtualenv's interpreter discovery would skip it instead of failing entirely.

(I have another Android device - a Nokia N20 tablet with Android 13. Tox and virtualenv work fine on it in Termux 0.118.0. The default $PATH is shorter and doesn't mention /system_ext)
