SSL certificate error during “pip3 install joulescope”

Issues
5

Hi @audiobrian1

Something is not right about your pip3 install. The error is that it cannot verify the SSL certificate of pypi. I just installed Python 3.8.3 x64, and I verified that pip &pypi are working, at least for me:

>python -VV
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)]

>pip3 install --no-cache-dir joulescope

Are your paths correct? Try:

> where python
> python -VV
> where pip3

I get:

c:\>where python
C:\bin\Python3_8_3\python.exe
C:\Users\Matth\AppData\Local\Microsoft\WindowsApps\python.exe

c:\>python -VV
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)]

c:\>where pip3
C:\bin\Python3_8_3\Scripts\pip3.exe

Make sure that they all match what you expect.

A google search turns up some recommendations. Are you behind a corporate firewall that blocks connections? I normally would not recommend disabling SSL verification, but you can do that…
