Can you try the latest main branch of build? I think the error might be nicer there.

i met the same error, my python=3.7, pip version=22.3.1, operating system is Windows. it said cann't get hatchling/ because of SSL error, but i come to the source site where does exists hatchling from 0.10.0 to 1.9.0 and also i can install other modules(include build0.10.0) using my pip. Looking forward to your help. Here is the log:

Hi @lien-Gu @henryiii I am getting the same error. Just like you, I am able to install packages using pip however it fails with "WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available." when using the build module. It popped up randomly this week and I have tried all solutions I could find on the internet such as this one: https://stackoverflow.com/questions/45954528/pip-is-configured-with-locations-that-require-tls-ssl-however-the-ssl-module-in.

Were you able to solve your problem?

[henryiii]

For a quick possible fix, you can try using build[virtualenv] when you install build - that will use a modern, up-to-date copy of pip. Another option is to use -n / --no-isolation when building, which will use your current environment instead of creating one and installing everything you need in it.

Do you have any special PIP_* variables set?

[mattgleesonmicrosoft]

Hey @henryiii , thanks for the quick suggestions! build[virtualenv] did not work but --no-isolation option does build successfully. I think this points towards some sort of problem with the virtualenv interpreter not having access to/having a malformed ssl module. Will update this thread if I find a fix

[gschlafly]

I was getting the same error message using python 3.9.16 on Windows OS. Trying to install build[virtualenv] as @henryiii suggested did not work either. I was in a conda environment. After deactivating the environment, python -m build worked as expected. That may work for you! @lien-Gu @mattgleesonmicrosoft

[ikost]

I confirm to have similar problem when running the build offline. When on Internet - everything works fine. Why would one need Internet connection to build the sdist?Hmm..

[henryiii]

You need the Internet to get packages to set up the isolated virtual environment, which is the default. If you want to manually install all of the build dependencies for the package you want to build an SDist for yourself (setuptools or flit or poetry or something else), you can use the no isolated environment flag.
