"Error: Location '$PWD/radish' to load modules does not exist" on Windows during running features

[Freudenberger]

Following the instruction from:
http://radish.readthedocs.io/en/latest/installation.html
and
http://radish.readthedocs.io/en/latest/quickstart.html
instead of running the tests with command
radish features/
an error occurs:

Error: Location '$PWD/radish' to load modules does not exist

Traceback (most recent call last):
  File "d:\workspace\radishSample\venv\lib\site-packages\radish\errororacle.py", line 52, in _decorator
    return func(*args, **kwargs)

    raise OSError("Location '{0}' to load modules does not exist".format(location))
OSError: Location '$PWD/radish' to load modules does not exist

According to https://github.com/radish-bdd/radish - it should be possible to run it on Windows without any modifications.

Tested with following versions:

radish-bdd (0.8.3)
radish-parse-type (0.3.5)

OS:

OS Name	Microsoft Windows 10 Pro, 64-bit
Version	10.0.16299 Build 16299

Python:
Python 3.6.4, 32-bit

It seems that in the utils module the flattened_basedirs(basedirs) function split on the ':' character,
which is on windows the separator of the drive letter (example D:dir1).
Here is a workaround, you can put the calculator module in the same directory as steps.py and use the -b option (radish features -b radish).
The workaround was tested with Python version 2.7.13 and radish -version 0.8.3.
Here are the details.

>ls radish
calculator.py  steps.py  terrain.py  
>ls  features
SumNumbers.feature
>cat radish/calculator.py
 # -*- coding: utf-8 -*

class Calculator(object):
    def __init__(self, caching=True):
        " init "
        pass
    def add(self, xxx, yyy):
        " addition "
        return xxx + yyy
    def sub(self, xxx, yyy):
        " substraction "
        return xxx - yyy
    def mult(self, xxx, yyy):
        " multiply "
        return xxx * yyy
    def div(self, xxx, yyy):
        " divide "
        return xxx / yyy

>radish features -b radish
Feature: The calculator should be able to sum numbers  # features\SumNumbers.feature
    In order to make sure the calculator
    sums numbers correctly I have the following
    test scenarios:

    Scenario: Test my calculator
        Given I have the numbers 5 and 6
        Given I have the numbers 5 and 6
        When I sum them
        When I sum them
        Then I expect the result to be 11
        Then I expect the result to be 11

Thanks for explanation @paul-divine
Unfortunately, I don't have access to a Windows environment.
PR to keep radish Windows compatible are always welcome!

[timofurrer]

For now, please use -b or multiple times -b.
As explained above, I don't have access to a windows to test this right now. However, I'm always happy to review PRs.

I am encountering this issue as well. If this is fixed, I'd love to know about it.

[fliiiix]

@7ep can you share the versions you are using? (radish, python, etc.)

[7ep]

Radish version: 0.10.0
Python 3.7
Windows 10

[fliiiix]

I reproduced this issue, fix will follow hopefully this week.

[vrbcntrl]

I am also getting the same error on my windows 10 machine...
I have radish v 0.13.1
Pls let me know if there is a fix for this issue...thanks in advance!

[fliiiix]

This issue here was fixed.
So my guess is you are trying to run radish without -b basedir.

So when you provide no basedir it only works for Linux. But I create a pr to create a similar behavior on windows: #354

[vrbcntrl]

Hi @fliiiix ,

I actually tried with -b parameter also

C:\Training\radish-bdd>radish -b C:\Users\vrb.cntrl\AppData\Local\Programs\Python\Python37\Lib\site-packages features/

and I got the below error:

site-packages isn't your radish base directory. Checkout: https://github.com/radish-bdd/radish/tree/master/tests/exploratory/basic

For example there your base directory is radish so you would run:

radish -b radish feature/SumNumbers.feature
