pserve: "No such file or directory --reload" (or any other option flag)

[Chris Shenton]

I've been using "pserve --reload myenv.ini" forever and recently the flags stopped working. Perhaps it's me, or perhaps I didn't pin versions in my setup.py file, but the "--reload" and other flags which used to work with pserve are no longer recognized. 

My .ini has:

[server:main]

use = egg:waitress#main

host = 0.0.0.0

port = 54321

I tried pinning the versions and saw this on pyramid==1.6.1 and today on pyramid==1.7.

```

./.venv3/bin/pserve --reload chris.ini

FileNotFoundError: [Errno 2] No such file or directory: '--reload'

```

Trying other flags has the same failure:

./.venv3/bin/pserve --browser chris.ini

[...]

FileNotFoundError: [Errno 2] No such file or directory: '--browser'

Flipping order, same problem:

./.venv3/bin/pserve chris.ini --reload 

[...]

FileNotFoundError: [Errno 2] No such file or directory: '--reload'

I've tried it by drilling down to the 'pserve' script in the Pyramid distribution and see the same thing:

python ./.venv3/lib/python3.4/site-packages/pyramid-1.7-py3.4.egg/pyramid/scripts/pserve.py --reload chris.ini

[...]

FileNotFoundError: [Errno 2] No such file or directory: '--reload'

Its as if the  optparse in pserve.py isn't parsing options properly but that seems unlikely to me. 

If nobody else is seeing this (nothing found in searches), do you have any ideas what I'm doing wrong? 

Thanks!

Something has likely become corrupt in your virtualenv. I'd try creating a new one. This is not a but with the pserve code itself but rather your environment.

This same thing has happened to me a few times when environment vars got screwed up.  You may just need to `source ./.venv3/bin/activate`

No. He is calling pserve from his bin directory directly, that’s perfectly acceptable, and is actually what we recommend in the docs.

We don’t recommend “activating” the virtualenv.

FWIW, I've recreated the virtualenv a couple times, before pinning all the versions, and after pinning with pyramid-1.7. Same behavior. :-(
