The example code doesn't run

[shi-yan]

run

python3 code_browser.py ../

as suggested by the doc gives

Traceback (most recent call last):

Presumably you have a copy of Textual installed, perhaps via pip? And you then pulled the code down from GitHub to test out the examples? If that is the case can you confirm what version of Textual you have installed, and when you cloned the code to get the examples?

Also, what happens if you try python3 -m textual? If the demo runs up, what is the version number towards the bottom of the sidebar (press Ctrl+b to make it appear).

Any other information about how you set up Textual and the examples would be very helpful in helping you.

Note that, testing here, with 0.6.0, I'm running the examples just fine.
