Hi

I already installed package as below
pip install twstock
pip install analytics

But when I start coding via import twstock

Traceback (most recent call last):
File "d:/Project/A00 Test/stock.py", line 1, in
import twstock
File "C:\Users\10802304\AppData\Roaming\Python\Python37\site-packages\twstock_init_.py", line 3, in
from twstock import stock
File "C:\Users\10802304\AppData\Roaming\Python\Python37\site-packages\twstock\stock.py", line 20, in
import analytics
File "C:\Users\10802304\AppData\Local\Continuum\anaconda3\lib\site-packages\analytics_init_.py", line 23
except Exception, e:
^
SyntaxError: invalid syntax

It seems analytics is incompatible with twstock due to using python2 older version.
Any idea?

Hi @HANK538,

You should not install "analytics", which is not used by twstock, twstock is using its analytics module (twstock/analytics.py), since you install analytics package (pip install analytics), it caused python to find another package.

You can remove the analytics package by $ pip uninstall analytics, it should solved this issue.

Anyway, it is encouraged to use $ python -m pip ... to execute pip, since using pip alone you will not sure which python interpreter is been used for the pip.

Hi @HANK538

I suggest you can open the file "C:\Users\10802304\AppData\Roaming\Python\Python37\site-packages\twstock\stock.py", and find maybe at line 16 have this:

 try:                                                                                                                                                                                                                                       
     from . import analytics                                                                                                                                                                                                                
     from .codes import codes                                                                                                                                                                                                               
 except ImportError:                                                                                                                                                                                                                        
     import analytics                                                                                                                                                                                                                       
     from codes import codes

Please replace it to this

try:
    from . import analytics
    from .codes import codes
except ImportError as e:
    print('Error: ', e)
    import analytics
    from codes import codes

Check and paste the otuput of what causing this ImportError, thanks

Thank you for the prompt reply!

ModuleNotFoundError: No module named 'lxml'

It works now after installed twstock and lxml package.

By the way, I just followed below blog so that's why I installed analytics package.

Thanks a lot.

Thanks for your reply, this should consider as a bug that not intent to be (Is because the dependency lxml didn't install, not because import relative package causing an error).

I'll reopen this issue to fix it.
