How to resolve this UnicodeEncodeError while installing eth-brownie on Windows10 with pipx?

Question

I tried to install eth-brownie on a Windows 10 PC running anaconda python. Python version is 3.9x

I followed the instructions here;

https://eth-brownie.readthedocs.io/en/stable/install.html

I ran the command below;

$ pipx install eth-brownie

I received the error below.

Answer 1

According to this bug report on pipx's GitHub page, this was fixed in #811.

The steps below should solve your problem:

1. Install cython via the command

    pip install cython
   

2. Run the command to install the package:

    pipx install eth-brownie
   

If the above doesn't work, try directly using pip to install the package:

pip install eth-brownie

Answer 2

I encountered the same error and use the same system configuration. I am using a Windows 10 PC running anaconda python. Python version is 3.9x

Here are the steps I run to install brownie successfully;

From https://eth-brownie.readthedocs.io/en/stable/install.html,

To install pipx:

$ python3 -m pip install --user pipx

$ python3 -m pipx ensurepath

To install a newer version of pipx that fixes the error reported (see https://github.com/pypa/pipx/issues/819);

$ pip install -U git+https://github.com/pypa/pipx.git@main

After this stage, I encountered one more error -> Cannot open include file: 'io.h': No such file or directory

The solution was to install Windows 10 SDK.

The description of the fix can be found here; Cannot open include file: 'io.h': No such file or directory

Finally, eth-brownie can be installed successfully using the following command;

$ pipx install eth-brownie
