Thanks for sharing! If you're trying to install a particular version of a package, you can include it after the package name like this "pip3 install eth-brownie==1.17.2"
On a Debian-based Linux, those dependencies are installed by the python3-dev package.
Thanks for posting the Windows solution, way too many combinations to guarantee a smooth install. It should go better for you now that you're running 🤞
Ganache is useful if you're going to be deploying and testing smart contracts (we do this later in the smart contract arbitrage series). For now, Python 3 is all you need and I mainly use Brownie as a simple wrapper for the web3py library.
thanks for the fast response. so if I understand correctly the dependencies stated are not requirements or something. they are semi-dependencies for full application / use of eth-brownie.
just installed eth-brownie... version 1.19.0, on we go.
I am very new but I really I am trying. I downloaded Pop! OS. I tried running the apt command in the terminal tab to try to get python3-venv version 3.9.2and python3-pip version 20.3.4...it does not work that way. "It says it is not available but it is refereed to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source." What am I missing?

Got it thanks for fast response!
For anyone newer using Mac that doesn't have Xcode installed and also doesnt have enough disk space to download the whole thing all you need is the xcode command line tools. Download directed from terminal using:
i am having a problem running brownie on arch.... any help ImportError: /home/unchained/.local/lib/python3.10/site-packages/cytoolz/functoolz.cpython-310-x86_64-linux-gnu.so: undefined symbol: _PyGen_Send
I'm using 3.9 so my experience is limited, but I found an encouraging bug report at https://github.com/pytoolz/cytoolz/issues/151 where the fix is to `pip install cython` followed by `pip install cytoolz`
Thought I would add this solution to a bug I had while installing.
The bug was that the install for eth-brownie would fail using pip.
The eventual solution involved installing Cython, cytoolz, and then trying the eth-brownie install an nth time.

edit: still not getting the right brownie version. Am getting 1.16.4 from pip. will update progress when I figure it out.
2nd edit: Finally got brownie 1.17.2 by cloning its repo and using setup.py to install the 1.17.2. Victory!!

this worked for me thnx
Thanks for that. It seemed to work for me.
also had issues installing eth-brownie.
Had to install Microsoft Visual C++ 14.0+ with 'C++ build tools' and 'Universal Windows Platform build tools' (for the Windows 10 SDK)
don't know whether I need all of what's in those packs but fck it, it works

on a different machine: 'pip failed to build package: cytoolz',
Had to run "pip install cython"
Then uninstall Python 3.10, install 3.9, run "pip install eth-brownie" for the latest version, as mentioned by @Summoneering
Python 3.10 plays poorly with the latest eth-brownie from pip. I posted a one-liner fix on Twitter, check it out:

hey there. thanks for the blog/substack. just starting up and going to see where I can contribute.
I noticed that brownie needs python3 and ganache (dependencies). Is it recommended to have both? Or is python3 enough.
Then if ganache is needed, it also requires node.js, npm, and I'm kinda going into jungleville here. ie unsure if this is the right path.
Ganache is useful if you're going to be deploying and testing smart contracts (we do this later in the smart contract arbitrage series). For now, Python 3 is all you need and I mainly use Brownie as a simple wrapper for the web3py library.

just installed eth-brownie... version 1.19.0, on we go.
Yes sir you've got it, everything that you need to run Brownie standalone is pulled in via 'pip install' or the pipx equivalent
I am very new but I really I am trying. I downloaded Pop! OS. I tried running the apt command in the terminal tab to try to get python3-venv version 3.9.2and python3-pip version 20.3.4...it does not work that way. "It says it is not available but it is refereed to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source." What am I missing?
Please post the exact command that is giving you that error and I'll help sort this out.
nvm I figured it out
With what we are building could I use a raspberry pi?
Assuming that our toolkit is available on the ARM architecture, everything will work as expected.
The bot itself needs very few resources, all of the blockchain work is being done through a remote node.
Really green here. Does anyone have a setup tutorial for an M1 Mac?
I don't have an M1, but this recent stackexchange discussion suggests that a native method is possible — https://ethereum.stackexchange.com/questions/128654/brownie-unable-to-compile-contracts-on-apple-m1-mac
On a Mac, installed python 3.9.7.
Checked that pip is installed and it is version 22.0.4.
Then installed both cython and cytoolz without issue.
Setuptools and wheel I made sure are also installed and up to date.
Not sure if I'm doing this right installing eth-brownie giving me issues.
Tried:
"pip install eth-brownie"
"pip3 install eth-brownie==1.17.2"
"pip install eth-brownie==1.17.2"
All gave me a bunch of errors:
"Building wheels for collected packages: bitarray, cytoolz, lru-dict

then tried to clone repo and install via setuptools via:
git clone https://github.com/eth-brownie/brownie.git
cd brownie
python3 setup.py install
but getting error: "xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun"
also
"-bash: cd: brownie: No such file or directory"
I'm doing this all from command line. Really appreciate any help you can point me towards!
Thank you
I'm flying a bit blind here since I don't have a Mac, but some quick googling tells me that xcrun is missing, which is part of the xcode package.

I've seen reports that Python v 3.10 creates weird package incompatibility issues. Are you using that?
Here's a relevant thread with that same error — https://ethereum.stackexchange.com/questions/115371/brownie-deployment-keyerror-openzeppelin-openzeppelin-contracts4-4-0-addres
installed python 3.9, uninstalled 3.10, and ran "python -m pip install eth-brownie" and now i have brownie v1.18.1
Excellent! Brownie just released v 1.18, and I've tested it against my bot code and it works with no problem. Good to go 👍
i am having a problem running brownie on arch.... any help ImportError: /home/unchained/.local/lib/python3.10/site-packages/cytoolz/functoolz.cpython-310-x86_64-linux-gnu.so: undefined symbol: _PyGen_Send
it seems brownie doesnt work with python 3.10, changing python versions will probably break alot of things on my system
I'm using 3.9 so my experience is limited, but I found an encouraging bug report at https://github.com/pytoolz/cytoolz/issues/151 where the fix is to `pip install cython` followed by `pip install cytoolz`
