Did you create a filled called “textual.py”? This will break things. The fix is to rename it to something else. |

Oh man! I was excited by this because I thought I may have done this but the only file I created like this was textual1.py. I went ahead and deleted that just in case but I still get the same error. I don't have a textual.py in any of my directories. |

What happens if you do this? python -c "import textual; print(textual)" |

Could you run this in your Python REPL please? from importlib.metadata import version; version( "textual" )and say what you get back? The reason I ask is that The current stable version is v0.9.1. |

Thanks for responding Dave.
Yes, I get back: ‘0.1.18’
So I thought I would try to update the textual library with:
pip install "textual[dev]"
and I get the following:
pip3 install "textual[dev]"
Requirement already satisfied: textual[dev] in /home/mjohnson/.local/lib/python3.8/site-packages (0.1.18)
WARNING: textual 0.1.18 does not provide the extra 'dev'
Requirement already satisfied: rich<13.0.0,>=12.3.0 in /home/mjohnson/.local/lib/python3.8/site-packages (from textual[dev]) (12.5.1)
Requirement already satisfied: typing-extensions<5.0,>=4.0.0; python_version < "3.9" in /home/mjohnson/.local/lib/python3.8/site-packages (from textual[dev]) (4.2.0)
Requirement already satisfied: pygments<3.0.0,>=2.6.0 in /home/mjohnson/.local/lib/python3.8/site-packages (from rich<13.0.0,>=12.3.0->textual[dev]) (2.11.2)
Requirement already satisfied: commonmark<0.10.0,>=0.9.0 in /home/mjohnson/.local/lib/python3.8/site-packages (from rich<13.0.0,>=12.3.0->textual[dev]) (0.9.1)
And if I run your command again, it still says I’m on the 0.1.18 version. So how do I get it to the latest? Thanks again.

The reason I ask is that ComposeResult wasn't introduced until the merge of the "CSS branch", resulting in v0.2.0 being released back in October last year<https://urldefense.com/v3/__https:/github.com/Textualize/textual/releases/tag/v0.2.0__;!!ATHtS6w!c6_2bSPdAYC4lPXCqjmpvXKvWlB_B9pvEOgMSB8Mvpri6xjzmis-3gxeWtBARQU1v3Re6E5SC6TR8mvxAaGlVUPR$>. If I do what you're doing, but with v0.1.18 or earlier<https://urldefense.com/v3/__https:/github.com/Textualize/textual/releases/tag/v0.1.18__;!!ATHtS6w!c6_2bSPdAYC4lPXCqjmpvXKvWlB_B9pvEOgMSB8Mvpri6xjzmis-3gxeWtBARQU1v3Re6E5SC6TR8mvxAZevyHJD$>, I get the same result as you. My suspicion is that you're looking at our current documentation, which is for the current versions of Textual, but you've got an older version installed.
The current stable version is v0.9.1<https://urldefense.com/v3/__https:/pypi.org/project/textual/__;!!ATHtS6w!c6_2bSPdAYC4lPXCqjmpvXKvWlB_B9pvEOgMSB8Mvpri6xjzmis-3gxeWtBARQU1v3Re6E5SC6TR8mvxAb8c_Msg$>.

Very new to Textual and Python in general. I’m trying to run and play with some of the examples. Several have the following import line:
from textual.app import App, ComposeResult
When I try running this line, I get the following error:
ImportError: cannot import name ‘ComposeResult’ from ‘textual.app’
In looking at another post, it was recommended to run:
python3 -m textual
to see a list of its capabilities. I'm also not able to run this line. In this case, I get the following:
No module named textual.main; 'textual' is a package and cannot be directly executed
I have installed the Textual library successfully and noticed that I can import things from textual but not textual.app. Is that something else? Sorry for the cluelessness but I don’t know enough yet on how to find out for myself. (I've tried Googling several things but I must be missing something very fundamental that I can't find. Thank you.
