I'm sorry in advance if this is a stupid question. I am trying to update the version of pants in our repo. We are currently running 2.8, and I see the stable version is 2.11. Following the advice on the following documentation page, I am trying to update one minor release at a time. So I am starting with trying update to 2.9 https://www.pantsbuild.org/docs/upgrade-tips#check-for-updates-to-the-pants-script I started by updating the pants executable with

curl -L -o ./pants <https://pantsbuild.github.io/setup/pants>

Then I updated the pants.toml file with

pants_version = "2.9.0"

I did

./pants package ::

And it packaged everything fine. But then I tried testing it by opening a repl environment for one of our modules, and I got the following error:

I had to remove some of the traceback which showed proprietary info, but hopefully the error is clear. I am not sure how to handle these errors, since the requirements were imported fine before the pants update, so I think I might have missed a step or done something wrong. Could anyone please provide some advice on how I can resolve this? Thanks

There are none

Hahaha sorry I accidentally hit enter which sent just the first line before typing the rest of the post.

Oh I meant there are no stupid questions!

Yeah, we don't believe in shaming people here for having questions. Pffft.

hehe.. you get more replies about your question not being stupid, than for your actual question 😛 but I was about to say the same…

I’m sorry in advance if this is a stupid question.

No such thing here 😉

Unrelated to your problem, but FYI you don't need to upgrade the pants runner script (https://pantsbuild.github.io/setup/pants) when you update the pants version

Yes, that's exactly what I'm doing, in a bash terminal. More specifically, I am using the :dist target.

./pants repl path/to/package:dist
