Colcon build -> env: Argument list too long

[danicannt]

Hi,

I am trying to compile Autoware in a computer that uses ROS2 Galactic and Ubuntu20,
The computer is using Python 3.8.10
I've been able to make it work successfully in other computers that we have around but I have two where I tried and I am getting the exact same errors when I try.

[6.152s] ERROR:colcon.colcon_core.shell:Exception in shell extension 'sh': Expected ['.', '/home/dcanton/source/external/autoware/build/tier4_auto_msgs_converter/colcon_command_prefix_build.sh', '&&', 'env'] to pass: /bin/sh: 1: env: Argument list too long

Have this happened to anyone before?.
Thanks!

Please take a look at #485, which exhibited the same symptom. In that case, the problem originated in the user's environment variable setup within their bash profile.

Could you please give me some more info?

I get that there is some problem with some environment variable ($PATH?) but I don't how did you be able to fix it
