Virtualenv: Virtualenv 20.0.0b1 error al crear venv para brew python2

Creado en 28 ene. 2020 · 10Comentarios · Fuente: pypa/virtualenv

En mi Mac con Homebrew Python2 (y 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

Yo obtengo:

$ 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())
  File "/Users/brettmz/Library/Python/3.7/lib/python/site-packages/virtualenv/__main__.py", line 16, in run
    run_via_cli(args)
  File "/Users/brettmz/Library/Python/3.7/lib/python/site-packages/virtualenv/run/__init__.py", line 21, in run_via_cli
    session = session_via_cli(args)
  File "/Users/brettmz/Library/Python/3.7/lib/python/site-packages/virtualenv/run/__init__.py", line 33, in session_via_cli
    raise RuntimeError("failed to find interpreter for {}".format(discover))
RuntimeError: failed to find interpreter for Builtin discover of python_spec='/usr/local/bin/python2'

Esto funciona sin errores para virtualenv estable actual. ¿Es esto intencionado?

Con la versión beta sin modificar, esto funciona:

virtualenv --python=/usr/local/bin/python2.7 foo

Cualquiera de los dos funciona con su rama actual discovery .

Gracias por su respuesta rápida.

Hmmm, no puedo reproducir esto 🤔 ¿puedes publicar la salida con -vvv ?

Esta parte parece la información relevante:

Parece que de alguna manera /usr/local/bin/python2 traduce en /usr/local/bin/python2.7 ... ¿Qué significa /usr/local/bin/python2.7 también?

gaborbernat en 28 ene. 2020

Da:

$ 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

Iniciar el intérprete directamente con /usr/local/bin/python2 funciona bien, pero supongo que eso se deriva del hecho de que funciona desde virtualenv anterior.

$ /usr/local/bin/python2

Creo que https://github.com/pypa/virtualenv/pull/1513 solucionará esto si puedes intentarlo 🤔

gaborbernat en 28 ene. 2020

Para ser justos, la prueba correcta aquí sería intentar crear una pitón primero con /usr/local/bin/python2.7 y luego /usr/local/bin/python2 ... y ambos deberían funcionar.

gaborbernat en 28 ene. 2020

Creo que https://github.com/pypa/virtualenv/pull/1513 solucionó esto, al menos de acuerdo con mis pruebas, si no, no dude en informarnos y volveremos a abrir el problema.

Con la versión beta sin modificar, esto funciona:

virtualenv --python=/usr/local/bin/python2.7 foo

Cualquiera de los dos funciona con su rama actual discovery .

Gracias por su respuesta rápida.
