--no-cache-dir causes AssertionError in wheel.py

[austinmw]

Environment

• pip version: 19.0
• Python version: 3.5
• OS: Ubuntu 16.04

This issue is caused while building a Dockerfile

Description

A Dockerfile that previously built many times successfully stopped working. I looked into the issue, and pip installing with--no-cache-dir began causing an AssertionError in wheel.py.

Expected behavior
No error

How to Reproduce
Inside Dockerfile, building with the line: RUN pip install -U --no-cache-dir numpy scipy sklearn pandas Pillow h5py tensorflow-serving-api==1.12.0 boto3 tqdm scikit-image

Output

Exception:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/pip/_internal/cli/base_command.py", line 176, in main
status = self.run(options, args)

This looks like a duplicate of Issue #6158. @austinmw it would be good to have you join the discussion there as well.

Oops sorry, missed the open one

[coderanger]

It isn't a duplicate of 6166, 6166 does not include the same argument.

Closing as the underlying issue is same as #6158.
