I did not expect pip to tell me to upgrade pip just after pip upgraded pip. And I did not expect pip to give me instructions that didn’t work.
What is this?
- Expected outcome.
- Bug in 3.14.0rc1. (Let’s tell the devs.)
- Bug in pip 25.1.1. (Let’s tell the devs.)
- PEBCAK. (Let’s keep it a secret.)
Note well:
- For 35 years, I have been cursing at a cmd prompt, and for 26 years, I have refused to ~$:.
- I’m not a programmer.

- I like that the Linux install seems to attempt to upgrade pip during the installation. (
Installing collected packages: pip // Successfully installed pip-25.1.1) - (I struggled to figure out the WWWWH of pip.)
- I used my Windows Python knowledge to upgrade pip somewhere. (
hunte@duda:/opt/python/3.14.0rc1-gil$ /opt/python/3.14.0rc1-gil/python -m pip install -U pip) - The interpreter told me I am a good boy, “Successfully installed pip-25.2”, and then told me I didn’t do what it had just told me that I had done, “A new release of pip is available: 25.1.1 → 25.2”.
- So I followed the instructions, which are not quite the same as in Windows,
hunte@duda:/opt/python/3.14.0rc1-gil$ pip3.14 install --upgrade pip, but it still didn’t work.
