What is the full command you executed?

@shenchucheng

I get the same error when running the iterative guide using the given command in the documentation:

metagpt "Add a randomly appearing enemy that lasts for 5 seconds. If the enemy is eaten, the game ends. If the enemy is not eaten, it disappears after 5 seconds." --project-path "snake_game" --run-tests --n-round 20 --max-auto-summarize-code 1

The project path generated by metagpt is under workspace folder, such as workspace/snake_game. It seems that you filled in the --project-path parameter incorrectly, which is why metagpt could not find the source code and gave the error. It is recommended to use an absolute path.

If there are no further questions, this issue will be closed. If you have any other questions, you can reopen this issue or create a new one.

Just tried it with the "workspace/snake_game"

However I still get the trace coming back to the original error:

However after running the same command again it feels like it goes beyond and I get the same error as has been raised in the grouping:
