ImportError: cannot import name 'inject_into_urllib3' from 'urllib3.contrib.pyopenssl'

ImportError: cannot import name 'injectintourllib3' from 'urllib3.contrib.pyopenssl'

TL;DR: urllib3 2.x made PyOpenSSL injection the default and deleted the contrib module. Delete the inject_into_urllib3() call entirely; there is nothing left to inject.

ImportError: cannot import name 'inject_into_urllib3' from 'urllib3.contrib.pyopenssl'

The fix

1. Remove the injection block:

import urllib3.contrib.pyopenssl
urllib3.contrib.pyopenssl.inject_into_urllib3()

On urllib3 2.x this code does nothing useful even when it imports.

1. If you cannot edit the code yet, pin as a stopgap:

pip install "urllib3<2"

1. Verify:

python -c "import urllib3; print(urllib3.__version__)"

Expected output: 2.x with no ImportError.

When this applies

• The code worked on urllib3 1.x and broke after upgrading to 2.x.
• Old requests/urllib3 bootstrap snippets in your codebase or vendored deps.
• The traceback names urllib3.contrib.pyopenssl.

When it does NOT apply

• cannot import name 'DEFAULT_CIPHERS', which is the other 2.0 private-API removal.
• You actually need PyOpenSSL features; on 2.x they are already active.

Why this happens

The injection API existed because old urllib3 used the stdlib ssl module by default and needed monkeypatching to use PyOpenSSL. In 2.0 the PyOpenSSL-backed path became standard, so the contrib module was deleted. Calling a deleted private API is the breakage; the behavior you wanted is now free.

Compatibility

urllib3 2.x removed the module. Deleting the call is correct on 2.x and harmless to keep working on 1.x if you must support both, guard it with a version check instead.
