PIP failed to build package cytoolz
Question:
I’m trying to install eth-brownie using ‘pipx install eth-brownie’ but I get an error saying
pip failed to build package: cytoolz
Some possibly relevant errors from pip install:
buildlib.win-amd64-3.10cytoolzfunctoolz.cp310-win_amd64.pyd : fatal error LNK1120: 1 unresolved externals
error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\bin\HostX86\x64\link.exe' failed with exit code 1120
I’ve had a look at the log file and it shows that it failed to build cytoolz. It also mentions "ALERT: Cython not installed. Building without Cython.". From my limited understanding Cytoolz is apart of Cython so i think the reason why the installation for eth-brownie failed is because it could not build cytoolz as it was trying to build it without Cython. The thing is I already have cython installed:
C:Usersalaiy>pip install cython
Requirement already satisfied: cython in c:python310libsite-packages (0.29.24)
Extract from the log file (I can paste the whole thing but its lengthy):

I used:
pip install eth-brownie
It worked fine, and I didn’t need to downgrade.
I’m new to this, so maybe I could be wrong, but it worked fine with me.
Managed to get it working with python 3.10.1 on Win10 x64 installing cython and cytoolz first:
python -m pip install --user cython
python -m pip install --user cytoolz
python -m pip install --user eth-brownie
I was having the same issue and did this…
python -m pip install --user cython
python -m pip install --user cytoolz
python -m pip install --user eth-brownie
python -m pip install --user pipx
python -m pipx ensurepath
# RESTARTED TERMINAL
pipx install eth-brownie
I was good to go then and could type in "brownie" in the terminal without getting an error. Some of the documentation I was reading had python3 and removing the 3 seemed to work.
Migrating OP’s solution from the question to an answer
Cython appears to not be supported on Python 3.10 (ref https://github.com/eth-brownie/brownie/issues/1300 and https://github.com/cython/cython/issues/4046). I downgraded to Python 3.9.7 and eth-brownie installation worked!)
