[reportlab-users] path error

[Robin Becker]

OK can you try the following commands

c:\python34\python.exe -c"import sys;print(sys.exec_prefix)"

on my system this gives

c:\python44


c:\python34\python.exe -c"import reportlab;print(reportlab.__file__)"

on my system I see

c:\code\reportlab\__init__.py

because I have reportlab installed specially for development. If your 
python/reportlab is correctly installed you should see something related to

C:\Python34\Lib\site-packages. If reportlab is not installed properly you won't.

I tried the experiments that were suggested by Adrian's suggestions in a virtual 
environment.

EG

> C:\code>\python34\python.exe -mvenv tempenv
>
> C:\code>tempenv\Scripts\activate.bat
> (tempenv) C:\code>cd tempenv
>
> (tempenv) C:\code\tempenv>python -c"import reportlab.pdfgen"
> Traceback (most recent call last):

so if reportlab is completely absent the message is
 > Traceback (most recent call last):
 >   File "<string>", line 1, in <module>
 > ImportError: No module named 'reportlab'

if there is some other module on the PYTHONPATH casued by my touch reportlab.py 
then you get the message you have been seeing eg

 > (tempenv) C:\code\tempenv>python -c"import reportlab.pdfgen"
 > Traceback (most recent call last):
 >   File "<frozen importlib._bootstrap>", line 2195, in _find_and_load_unlocked

however, even though it's not the right module/package you can still find out 
where it is using the __file__ attribute eg

> (tempenv) C:\code\tempenv>python -c"import reportlab;print(reportlab.__file__)"
> C:\code\tempenv\reportlab.py

so perhaps the second command I asked you to try above may help.
