I am having real trouble trying to use pip to install pyserial for python 3.5.2, I am trying to install pip using 'sudo easy_install pip'.
I keep getting this error message:
sudo easy_install pip
Traceback (most recent call last):

Any Help would be appreciated.
Running sudo easy_install pip will install pip for Python 2, which you don't want if you're using Python 3.
You might have pip installed for Python 3 already (run which pip3 to check). If so, you can install pyserial using pip3
pip3 install pyserial
However, it would be better to use a virtual environment. See the hitchhiker's guide to Python to get started.

I am confused on python on its installation path and configuration.
I know pip this command for installation or listing the modules.
The example is like pip freeze. It will show up the list of module.
Recently, I got an error when I execute pip. I had python2 and python3 on the system without any virtualenv. I use ls /usr/bin/python* -al | awk {print $9 $10 $11} to know python commands and ls /usr/bin/pip* -al to know the pip commands.
python->python2.7
python2->python2.7
python2.7
python2.7-config->arm-linux-gnueabihf-python2.7-config
python2-config->python2.7-config
python3->python3.4
python3.4
python3.4m
python3m->python3.4m
python-config->python2.7-config
pip pip2 pip3
In addition, I use ls on /usr/local/bin and know the pip commands.
pip pip2 pip2.7 pip3 pip3.4 pip3.5
The error message is this when I execute pip.

How to resolve this error? Why does the system show up the error?
The result is the conflict without a specific command.
Use python2.7 -m pip or python2 -m pip for a specific command. Vice versa, on python3, use python3 -m pip or python3.4 -m pip for a specific command.
In addition, use python or python3 to get into interactive mode. Then, use import sys and sys.path to get the path of python package.
Whenever I try to install anything using pip I get the following error:
$ sudo pip install --upgrade pip

This also happens when I try to upgrade pip, install sphinx or basically any install/upgrade option using pip.
I am running Ubuntu 15.10 and using Python 2.7.10
StackOverflow has said this is a duplicate, and that there is a solution at ImportError: No module named 'pip._vendor.distlib.scripts' when I try to install fabric by python pip however the recommend solution on this post is not actually a soltuion. It does not solve my issue, nor does it appear to solve the original posters problem.
Try this:
sudo pip install --upgrade --no-use-wheel pip
Using OSX El Capitan. Just installed a bunch of pip module and was following a few online tutorials, must have broken something as now I get the following error whenever I try to use pip (although python seems to run fine).
$ pip install pandas

Any helping fixing would be much appreciated.
Thanks.
Reinstall using easy_install. Close the terminal and reopen. Pip should now work.
Try updating pip first by typing pip install -U pip and the try pip install pandas. I myself use Anaconda/Miniconda. Most of the packages are well handled and the dependencies are taken care of as well by the conda package manager.
I can't get the ocdev tool to run. when I try running it i receive "SyntaxError: invalid syntax" with some code.
My guess is maybe wrong python version? Since python --version outputs 2.7.3.
I also have python3 installed but it's not the standard version. I installed ocdev using pip-3.2. I already tried reinstalling it multiple times. I also have python3-jinja2 installed. I'm running debian 7.8.
Here is the whole error:

SyntaxError: invalid syntax
In order to get ocdev to work with Python 3.2 you need to install legacy versions of Jinja2(source) and MarkupSafe(source). This is because the newer versions require Python 3.3.
To do the proper install follow the regular setup guide and use the following pip/pip3 commands:
pip install -Iv Jinja2==2.6
pip install -Iv MarkupSafe==0.15
pip install ocdev
I also reported this in the ocdev GitHub repository here.
It looks like you're running Python 3.2.
To use the u'unicode' syntax with Python 3 you'll need at least Python 3.3. (see What's New In Python 3.3)
I first installed distribute, then pip with easy_install but when I run:
sudo pip install virtualenv
I get these error messages:

I do not know what to do to install virtualenv properly now?
You appear to be using Python 2.4 - try creating the virtualenv with a version of Python which includes from __future__ import absolute_import (Python 2.5 or later).
You can specify which Python to use like this:
virtualenv -p /usr/bin/python2.7
