ETH-BROWNIE install issue - windows - pipx

Question

So I am trying to install eth-brownie via pipx as recommended, this on Windows. I tried everything also multiple re-installs of EVERYTHING including python. This one error just isn't fixable for me and googling this doesn't help.

PS C:\Users\XXXX\Desktop\solidity> python -m pipx install eth-brownie

Traceback (most recent call last):

This last python install was via Microsoft store, don't ask me why, but this error is the same if I download python via the normal way.

If anyone can help me I would be very grateful. Works fine on my laptop, but it's an old and slow one so need it on PC.

You may need to make your terminal capable of handling unicode: see [here](https://stackoverflow.com/questions/5419/python-unicode-and-the-windows-console) and [here](https://stackoverflow.com/questions/388490/how-to-use-unicode-characters-in-windows-command-line). — snakecharmerb, Feb 10 '22 at 13:22
Hi Snakecharmerb, Thank you for your reply! However I did not get any further. I installed win-unicode-console via pip, but got the same error as before. Also tried exporting, editing & importing the file from registry but to no avail. Any more ideas are very welcome — pythonnoobsadly, Feb 10 '22 at 15:20
I faced a similar error and managed to install eth-brownie successfully.

I'm pretty sure I just did it using pip instead of pipx:

python -m pip install eth-brownie

Hi Daniel, It might be possible yes, but you wont get the env handy part from using with pipx. So it might be possible, but you will need to put in more work I heard into managing your envs. Or is this incorrect? – pythonnoobsadly Feb 11 '22 at 13:04
ps got an error trying it with pip as well – pythonnoobsadly Feb 11 '22 at 15:01
Sorry, if that doesn't work I don't know – Daniel_Cawley Feb 11 '22 at 18:10

I had the same problem with python version 3.10.2 Downgraded python to version 3.9.2, installation of eth-brownie using pipx works fine.

"UnicodeEncodeError" is not the real error. It is encoding error when the script was trying to print the real error.

To fix this fake error,

vi "C:\Users\XXXX\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\pipx\util.py"
change from
   with pip_error_file.open("w") as pip_error_fh:
to
   with pip_error_file.open("w", encoding="utf-8") as pip_error_fh:

Then run your install script again, and you will see the REAL error.

Best thing to do is uninstall the python3.10 pipx venvs installation of eth-brownie. Make sure you also already have python3.9 installed on your computer. Then reinstall eth-brownie using python3.9

pipx uninstall eth-brownie
python3.9 -m pip install --user pipx
python3.9 -m pipx ensurepath
python3.9 -m pipx install eth-brownie

to add libraries to your eth-brownie pipx venvs

python3.9 -m pipx inject eth-brownie playsound
