Hello folks, I apologize in advance for what I'm going to ask since it relates to an older version (

1.23.0

). One of my projects started randomly failing the build process with pants. This is the more relevant part of the error but I'd be happy to provide the full error if needed. Has anyone else encountered similar issues?

Hello! You should be able to change the

./pants

bash script to use a newer version of pip

interesting, let me give that a shot

Interesting. 1.25 and 1.26 bring some nice benefits like being able to use file arguments (

./pants test path/to/file.py

) and

pants.toml

good to know thanks! I think I held off on upgrading to a

pants.toml

only version since I thought it might be a challenge but it was a breeze to bump up to

1.26

🙂

You can keep using pants.ini until 2.0 🙂 There's a script to automatically migrate ~75% of it also
