The executable python3.5 (from --python=python3.5) does not exist

[tomsitter]

Hey,

I'm trying to run this on Windows 10. After installing via pip I'm running into a couple separate issues

1. try is masked by Windows PowerShell's try syntax
2. Running as a python m (python -m try requests) results in the error:
   The executable python3.5 (from --python=python3.5) does not exist

I'm using Python 3.5 installed to C:\Python35\python.exe

Any help would be great!

Thanks for reporting 🍻

1. That's a pity. I'm not a windows user.. Could you alias it? I might think about supporting try and trypackage as a command? What do you think?
2. On my linux machine the following works: python3 -m try requests. Is the error raised by try or from someone else? Do you have python-virtualenv installed (no idea how the package is called on windows. But you should have a virtualenv command available)? In addition to that .. does powershell support a source command to source the virtualenv? If not I'll have to make some changes to support windows

I found that try.exe works to launch it (i.e. try.exe requests) which resolves issue 1. This command points to C:\Python35\Scripts\try.exe

As for the second error, running the command results in this printout

> try.exe requests
==> Use python python3.5
[*] Downloading packages: requests
[*] Failed to try package. See C:\Users\Tom\AppData\Local\Temp\try-3k4_q9ih.log for more details.

With the log file contents being the text:
The executable python3.5 (from --python=python3.5) does not exist

I tried pointing directly to my copy of python

> try.exe requests -v C:/Python35/python.exe
==> Use python C:/Python35/python.exe
[*] Downloading packages: requests
'.' is not recognized as an internal or external command,
operable program or batch file.
[*] Failed to try package. See C:\Users\Tom\AppData\Local\Temp\try-wdq_48u3.log for more details.

Which runs for longer period of time before encountering an error and gives me these log contents

Using base prefix 'C:\\Python35'
New python executable in env\Scripts\python.exe
Installing setuptools, pip, wheel...done.
Running virtualenv with interpreter C:/Python35/python.exe

Okay, thanks. I'll have a look at it as soon as possible!

[tomsitter]

Thanks, I added a few more details to my second comment.

I think this is coming from the second half of thebuild_virtualenv_cmd command.
Running the first part works fine (and gives the output noted in the final log contents above)

> virtualenv env -p C:/Python35/python.exe
Running virtualenv with interpreter C:/Python35/python.exe
Using base prefix 'C:\\Python35'
New python executable in env\Scripts\python.exe
Installing setuptools, pip, wheel...done.

But the second part && . env/bin/activate is no good on windows. The equivalent would be

return "virtualenv env -p {0} > {1}; ./env/Scripts/activate".format(python_version, logfile)

But unfortunately in powershell there are permission problems with virtualenv (discussed here)

I had no problem running the above command in Git Shell fortunately. If I have time I will try to fork this and add windows support for running in Git Shell.

Any luck on that one?

I had the same issue
Maybe it's because of python version.
$python3 --version
Python 3.4.0
So
from --python=python3.4
It worked

[Megaverse]

i did virtualenv -p3 virtual_env_name and this worked!

[timofurrer]

@saurabhmarpadge @Megaverse thanks for the confirmation.
I'm going to close this for now!

If anyone encounters the same issue please open a new ticket.
