After trying to do a "pip3 list" on MacOS after installing Python3 with Homebrew and while connected to a corporate network and firewall, I got the below error:
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1051)'))) - skipping
After some digging, I found this article. It works! Converting the company's .CER file to .PEM and then doing a "pip3 --cert root-cert.pem list" resolved the issue. However, where does the data get saved? Meaning, how does one revert the setting back to NULL or modify the setting without actually executing the command again using some phony .PEM file?

I'm using Jupyter notebooks with 32-bit Python. I'm using pip 21.2.4 and Python 3.9. When I try to install sqlalchemy-access
pip install sqlalchemy-access
I get these errors,
Could not fetch URL https://pypi.org/simple/sqlalchemy-access/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/sqlalchemy-access/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)'))) - skipping

Note: you may need to restart the kernel to use updated packages.
One reccomendation I recieved was to try specifying the url using:
pip install --index-url=https://pypi.org/simple/sqlalchemy-access/
But then I just get another error
The current directory is invalid.
Any tips? Thanks!

I followed some guides online, and tried and install through pip3 install --trusted-host pypi.org --trusted-host files.pythonhosted.org pip PyPDF2, but it shows
ERROR: Could not find a version that satisfies the requirement PyPDF2
(from versions: none) ERROR: No matching distribution found for PyPDF2
instead. I did try to update Python version but it still didn't work (Python version 3.9.12)
Could anyone tell me how I should fix these problems?
Thank you!
I am trying to install Dtale in jupyter notebook. Due to the firewall restrictions, I cannot install it online. I tried to download the archive file dtale-2.2.0.tar.gz and ran this command inside the jupyter notes.
pip install <path>/dtale-2.2.0.tar.gz
This fails as it could not find pypandoc. Then I downloaded the pypandoc-1.7.5.tar.gz and ran
pip install <path>/pypandoc-1.7.5.tar.gz.
But this time I get the error:
ERROR: Could not install packages due to an OSError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Max retries exceeded with url: /packages/d2/04/08841501db81bceb7a86a98dea7c12b0185fcc69bfdf1aea266f727d1d7e/poetry_core-1.0.8-py2.py3-none-any.whl (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)')))
I know the host is unreachable due to the firewall, that is the reason why I downloaded the package. Can someone guide me through how to install the packages from the .gz archive file?
Thanks
this error tells you that there is a pkg in dependencies that can NOT be downloaded.
its name is poetry-core, so you should download and install it manually.
here is a url for it: https://files.pythonhosted.org/packages/d2/04/08841501db81bceb7a86a98dea7c12b0185fcc69bfdf1aea266f727d1d7e/poetry_core-1.0.8-py2.py3-none-any.whl
in case you can't download it too due to your firewall, you can use VPN.
in case you can't do that either, then you can download it from this url:
https://www.mediafire.com/file/kpnfupmf5px84um/poetry_core-1.0.8-py2.py3-none-any.whl/file
I have downloaded and re-uploaded it
