Getting bootstrapper error when running the install command for version 1.4

I keep getting this error : "Welcome to the CS Tools Bootstrapper!

When I run the new install command: "(Invoke-WebRequest -Uri https://raw.githubusercontent.com/thoughtspot/cs_tools/master/cs_tools/updater/_bootstrapper.py

FYI I have Python version 3.7.6. I also tried on 3.11.1

Hi, this should be fixed now -- can you try again? I totally didn't replace my commitish reference target from during development. 🙃

Ok that worked! But now when i try to run cs_tools --version I get : ImportError: cannot import name 'Literal' from 'typing' (C:\Users\alexw\AppData\Local\Programs\Python\Python37\lib\typing.py)

Alright -- I've reproduced this on my 3.7.9 venv. This bug looks like it's coming from a combination of a few things and is going to take a bit of time to compat fix.

In the meantime, you mentioned you've got multiple versions of python installed, can you try using a later version?

So this is probably an issue on my end, but i installed python 3.11.3 and its located in 'C:\Users\alexw\AppData\Local\Programs\Python\Python311\pythonw.exe' but i get the error: " No Python at 'C:\Users\alexw\AppData\Local\Programs\Python\Python37\python.exe'
| Unexpected error in bootstrapper, see C:\Users\alexw\NULL.log for details.."

Update: I copied the contents of python311 to 37 and then ran it... and it Worked!! Thanks for the help! I'll let you know if i run into any more issues

When you install a new version of python on Windows, it gets added to the front of your PATH variable by default. Which means when you type python , the OS will go searching down the list of directories there. Python311 was sitting in front of Python37.

Whenever you create a virtual environment in python, all that's happening is it bootstraps a new directory and symlinks/references the then-system version of python.

No Python at 'C:\Users\alexw\AppData\Local\Programs\Python\Python37\python.exe'

So essentially what's happening is CS Tools is looking at the old directory and trying to call python , which resolves to python3.11 instead. Nuking the virtual environment, or replacing all the references, will get this working again.

(Invoke-WebRequest -Uri https://raw.githubusercontent.com/thoughtspot/cs_tools/master/cs_tools/updater/_bootstrapper.py
-UseBasicParsing `
).Content | python - --reinstall

--reinstall does just that, it nukes the CS Tools-managed virtual environment and then recreates it (effectively linking it to whatever version of python is referenced when you type python). 😄

It feels like magic unless you know how python venvs work.
