"codec can't encode character" error when I run "pipx install eth-brownie"

Not sure if this helps but I couldn't run "python3 -m pip install --user pipx" and "python3 -m pipx ensurepath". Instead of "python3" I just used "python" and also ran "python -m pipx ensurepath --force"
It told me pipx is ready to go and then I ran "pipx install eth-brownie" and got the below.
C:\Users\gmlad>pipx install eth-brownie

You can try to install brownie by clone from github repository like blow. Then after that you can delete all the code if you want. And you already can use the brownie cli on your computer.
git clone https://github.com/eth-brownie/brownie.git
cd brownie
python3 setup.py install

Try upgrading pip using:
python -m pip install --upgrade pip
If that doesn't work, then you might need to set your locale to UTF-8. There is a closed GitHub issue on the pipx repo regarding this issue: https://github.com/pypa/pipx/issues/73.

Before this I have installed the package "pyusb" without any problem, without getting any error.
I've searched in google for this error, but not getting a very good explanation.
How to solve this error?

This occurs if your current working directory has name with non ASCII characters.Example ¢, Ë, Ñ, ß etc.
Remove those from the directory or file name and you are good to go.

About this particular error: "UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 8: ordinal not in range(128)", when trying to upgrade pip or install any python packet, was related to the user folder name.
My user folder name was "C:/Users/Sérgio Neves", and the "é" in "Sérgio" was the problem, so I changed the user folder name to "C:/Users/SergioNeves", without any accent and space.
I followed this video to change the folder name:

The OSMnx installation instructions suggest using conda-forge to install. This is particularly important on Windows, as you want to avoid compiling all the C extensions required by the geospatial dependencies.
conda install -c conda-forge osmnx
Or if all else fails, do the install in a nice clean virtual environment:
conda create --yes -c conda-forge -n OSMNX python=3 osmnx
source activate OSMNX
That should solve any Windows-related install problems (and works for Mac and Linux too).

Pip spitting UnicodeDecode error

I'm not 100% positive as to what is the correct place to post this question since it's 50% programming since it's a python bug and 50% system management, since it's a bug on a package. I went on to post here, If I'm incorrect please direct me to the right place.
I'm currently running Arch Linux 64 bit and earlier today I updated a couple of packages including the (critical I believe) python-setuptools. Before this pip worked perfectly, no issues whatsoever, now however just from running the bare command I get the following:
espaco#Arch ~> pip

Is this something I did wrong or does pip have a bug? How would I be able to fix this?
What I have tried:
Reinstalling pip
Reinstalling python-setuptools
The almighty reboot
Ask my mom to kiss bash in the forehead
Search the Arch package list for a bug report
Google the problem

$ ll /var/cache/pacman/pkg/python-setuptools-*
then select desired version, and
$ sudo pacman -U /var/cache/pacman/pkg/python-setuptools-1:18.7-1-any.pkg.tar.xz
where 1:18.7-1 is your previous version of the package
if it will not help:
$ cat /var/log/pacman.log | grep 2015-11-30 | grep upgraded
and then for each package install it's previous version by doing part 1
you can write a script for that or find existing.
also try to search arch community forums

Python pip install error

I have just installed Python 3.4.3 on my MAC (Yosemite). I need to install a couple of lxml, however everytime I type in: pip install /""/, I get error messages.
I have followed multiple tutorials and pip is installed.
MAC already had Python 2.7., but I installed the 3.4.3. version, not sure if that is the issue.
The error message is:

Anybody knows what I could be doing wrong? Any help would be appreciated.

try:
easy_install pip
pip install /"filepath"/

I have similar issue with pip install. However, if I do "sudo su -" then do my pip install 'fileName', that solve the problem for me.
