Pipenv shell start error: FileNotFoundError: [Errno 2] No such file or directory: '/proc/xxxx/stat' : Forums : PythonAnywhere

Pipenv shell start error: FileNotFoundError: [Errno 2] No such file or directory: '/proc/xxxx/stat'

Hi all,

i'm trying to use pipenv, installing works, now I wanted to start the shell with pipenv shell and I got the error below. At first I thought I messed too much with pipenv, but in a new useraccount the same error occurs.

The directory '/proc/xxxxx/stat doesn't exist', so the error message is in my opinion correct, unfortunately I don't know how to fix this...

Hmm. Unfortunately that suggests that pipenv -- at least as you have it configured -- isn't compatible with our virtualization system. Could you give us the exact steps you did in order to get that trace?

Hello Giles,

first of all I'm a complete noob regarding python and pipenv but I've managed to install it on my laptop, was looking for a solution to use python in a easy way on multiple machines and pythonanywhere is great!

I tried to install pipenv according to this topic: Pipenv install. On the shell used the command pip3.6 install --user pipenv created a test dir in the test dir I used pipenv install request wanted to start pipenv shell

After that got an error message such as mentioned in the starting post. Looks like it wants to do something with the pid. I read somewhere else on the forum that you do not provide the pid or something like that.

Yeah. Sorry. As @giles said, it looks like it's just not compatible with our virtualisation system.

Use pipenv 2018.6.25

pip install pipenv==2018.6.25 --user

Then you may use pipenv shell properly.

This works thanks: pip install pipenv==2018.6.25 --user

But why doesn't the latest pipenv work?

@chris I believe we have been corresponding over email. Pipenv tries to access /proc/, which is not mounted for a regular user environment. this error can be worked around by using docker consoles, and this should let you use the latest pipenv. Do let us know if this you want to try this, and let us know if it works!
