Virtualenv: Erreur Virtualenv 20.0.0b1 lors de la création de venv pour brew python2
Sur mon Mac avec Homebrew Python2 (et 3) :
$ ls -al $(which python2)
lrwxr-xr-x 1 brettmz admin 37 Nov 15 12:04 /usr/local/bin/python2 -> ../Cellar/python@2/2.7.17/bin/python2
Je reçois:
$ virtualenv --python /usr/local/bin/python2 py2env
Traceback (most recent call last):
File "/Users/brettmz/Library/Python/3.7/bin/virtualenv", line 8, in <module>
sys.exit(run())

raise RuntimeError("failed to find interpreter for {}".format(discover))
RuntimeError: failed to find interpreter for Builtin discover of python_spec='/usr/local/bin/python2'
Cela fonctionne sans erreur pour virtualenv stable actuel. Est-ce prévu ?

On dirait que /usr/local/bin/python2 traduit par /usr/local/bin/python2.7 ... Qu'est-ce que /usr/local/bin/python2.7 pointe aussi ?

Il donne:
$ ls -al /usr/local/bin/python2.7
lrwxr-xr-x 1 brettmz admin 39 Nov 15 12:04 /usr/local/bin/python2.7 -> ../Cellar/python@2/2.7.17/bin/python2.7
Démarrer l'interpréteur directement avec /usr/local/bin/python2 fonctionne bien, mais je suppose que cela découle du fait qu'il fonctionne à partir de virtualenv plus ancien.
$ /usr/local/bin/python2

Je pense que https://github.com/pypa/virtualenv/pull/1513 corrigera cela si vous pouvez l'essayer

Pour être juste, le bon test ici serait d'essayer de créer un python d'abord avec /usr/local/bin/python2.7 puis /usr/local/bin/python2 ... et les deux devraient fonctionner.

Je pense que https://github.com/pypa/virtualenv/pull/1513 a résolu ce problème, du moins selon mes tests, sinon, n'hésitez pas à faire rapport et nous rouvrirons le problème.

Avec la version bêta non modifiée, cela fonctionne :
virtualenv --python=/usr/local/bin/python2.7 foo
Soit fonctionne avec votre branche discovery .
Merci pour votre réponse rapide.
