New submission from Charalampos Stratakis: The latest versions of setuptools stopped bundling its dependencies and instead starting requiring them [0]. This seems to break virtualenvs as those dependencies are not bundled with python.
In order to reproduce it, replace the setuptools-28.8.0-py2.py3-none-any.whl with setuptools-34.1.1-py2.py3-none-any.whl at Lib/ensurepip/_bundled/ and change _SETUPTOOLS_VERSION = "28.8.0" to _SETUPTOOLS_VERSION = "34.1.1" Then configure, make and make install: This message will appear first: Could not find a version that satisfies the requirement packaging>=16.8 (from setuptools) (from versions: ) No matching distribution found for packaging>=16.8 (from setuptools) Which is one of the new dependencies. Then: ./python3.7 -m test test_venv -v Where the EnsurePipTest will fail due to this assertion [1] at the do_test_with_pip test case with "No module named pip\n' != ''". One way to fix this would be to bundle the other wheels with python, not sure if that would be the ideal approach though. Attaching a patch for Lib/ensurepip/__init__.py. With this patch and adding the other wheels [2][3][4][5] at the _bundled directory fixes the issue.
