ROS Ament error

gistfile1.txt

**Copied from MicroROS slack thread**

**My Initial question**
Hi, my MicroROS project recently started to fail after I run clean.
If I restore it from a backup it compiles fine until i run clean/compile.I am running inside a container 
that is based off of espressif/idf:v4.4.6 and my host OS is Ubuntu 22.04My docker def is here 
https://github.com/gentijo/ROSMicroPy/blob/main/docker/Dockerfile.rbpyMy 
[micro_ros_espidf_component](https://github.com/micro-ROS/micro_ros_espidf_component) is installed as a sub component
the version is from a previous version of Humble, 
[895a1f8](https://github.com/micro-ROS/micro_ros_espidf_component/tree/895a1f8858481d0b39a0d76d5ee8ab4db932293f), 
which is roughly 3.0.1 which is a bit old but I tried to update to the latest Humble but the error is the same.

I am getting a syntax error when ament is running
My container Python version is Python 3.8.10I have a feeling that this happened after running apt upgrade some time 
in the past but I am lost on how to debug this.Has anyone seen this before ??
Any ideas where to look ??
Thank you
John

SyntaxError: invalid syntax 

**My analysis and solution**
Solved.  I had a previous computer that worked fine. It has all the same setup, Ubuntu 22.04, 
Docker versions and same build profile. Difference was the container was built about a month ago 
vs the new computer in the last few days.  I did a pip list on both containers, a few of the modules 
were newer based on the last time pip was run but they were only different by a point release. 
This was the cause of the problem.  It's not the difference of colcon-core, I tried that one by itself.  
I created a requirments.txt from the old computer and applied it to the new computer and it all worked. 
There must been a release in the past few weeks that has broken colcon/ament.
