I want to install pip for python 2.7, but I am also having python 3.x but both locations are different. when ever I install or update the pip It is installing in the python 3.x location.
How to install pip for python 2.7?
I recently found the following solution, when you are maintaining python2.x and python 3.x in host system. You can find the pip under Scripts folder.
Try pip --version it gives pip version and python version as well
If you want to install package using pip use the following commands.
python -m pip install package_name
python2.x -m pip install package_name
Which reads the specified python pip module to install the package

I'm trying to use pip to install some packages that I need, but I came across a problem. My default version of python is python3.10 but when I try using pip to install packages for it, it installes them for python3.8
This is the output of pip --version:
pip 22.1.2 from /usr/local/lib/python3.8/dist-packages/pip (python 3.8)
Is there a way to change this so that I can install packages for python 3.10?
When I try to run python3 -m pip --version I get:
/usr/local/bin/python3: No module named pip
Download get-pip.py file from any of the following options:
Download it manually from here.
Download it from terminal/cmd using: wget https://bootstrap.pypa.io/get-pip.py
Download it from terminal/cmd using: curl https://bootstrap.pypa.io/get-pip.py
Then run the command python3 get-pip.py, it will install pip in the python version invoked by python3(which is 3.10 as you have stated).
Install packages using command python3 -m pip install package_name
Since you've said you can call the desired python version with the command python3, it's best to call pip via
python3 -m pip
This ensures you're installing packages to the correct version (Dealing with multiple Python versions and PIP?).
To install pip if it's missing, you can use ensurepip (as per this answer)
python3 -m ensurepip
It's probably worth mentioning venv which lets you create a local python environment to keep your packages separate for different projects.
So my problem is that I have two versions of python: 2.7 and 3.2. I want to install pycrypto on the 2.7 one but when I try to do this:
python2.7 pip install pcrypto
Or:
pip2.7 install pycrypto
It says that python2.7 or pip2.7 is not a recognized command.
What should I do?
pip installs a library for any version of Python 2
pip3 installs a library for any version of Python 3
On linux terminal, type:
whereis pip
It will print all available paths to pip installations. Copy-paste the full path to the desired pip, e.g.:
/usr/local/bin/pip2.7 install pcrypto
If you want to use pip of a specific python interpreter you can use this interpreter with the -m option to use the specific pip.
python -m pip ...
... should be replaced with the desired pip commands.
The -m option allows to run a library module as a script (in this case the associated pip)
I have my deployment system running CentOS 6.
It has by default python 2.6.6 installed. So, "which python" gives me /usr/bin/python (which is 2.6.6)
I later installed python3.5, which is invoked as python3 ("which python3" gives me /usr/local/bin/python3)
Using pip, I need to install a few packages that are specific to python3. So I did pip install using:-
"sudo yum install python-pip"
So "which pip" is /usr/bin/pip.
Now whenever I do any "pip install", it just installs it for 2.6.6. :-(
It is clear that pip installation got tied to python 2.6.6 and invoking pip later, only installs packages for 2.6.6.
How can I get around this issue?
If pip isn’t already installed, then first try to bootstrap it from the standard library:
$ python3.5 -m ensurepip --default-pip
If that still doesn’t allow you to run pip:
Securely Download get-pip.py.
Run sudo python3.5 get-pip.py.
Now you can use pip3 to install packages for python3.5. For example, try:
$ sudo pip3 install ipython # isntall IPython for python3.5
Alternatively, as long as the corresponding pip has been installed, you can use pip for a specific Python version like this:
$ python3.5 -m pip install SomePackage # specifically Python 3.5

Ensure you can run pip from the command line
work with multiple versions of Python installed in parallel?
I have python 3.6 and 3.8 on my Ubuntu 18.04 WSL machine. Running
sudo apt-get install python3-pip
pip3 install my_package_name
kept installing packages into Python 3.6 dist directories. The only way that I could install packages for Python 3.8 was:
python3.8 -m pip install my_package_name
That installed appropriate package into the Python 3.8 dist package directory so that when I ran my code with python3.8, the required package was available.
Example of how to install pip for a specific python version
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
/opt/local/bin/python2.7 get-pip.py
Script is from official doc: https://pip.pypa.io/en/stable/installing/
On Ubuntu 18.04.1 LTS I wanted to install pip for my second python version (python3) and the following command did the trick for me:
$ sudo apt install python3-pip
I'm trying to install Python-Twitch for Python 3.4. I have both 3.4 and 3.5 installed on my computer, and in command prompt I do this:
python --version
Where it gives me Python 3.5.x. Then:
set PATH=C:\Python34\;%PATH%
And python --version will then read Python 3.4.x.
Once I do 'pip install python-twitch', it installs it to the Python 3.5 Lib/Site-Packages folder. How would I get this over to 3.4?
Thanks so much for any help.
I think this was already answered: pip: dealing with multiple Python versions?
Since version 0.8, Pip supports pip-{version}. You can use it the same as easy_install-{version}:
$ pip-2.5 install myfoopackage
$ pip-2.6 install otherpackage
$ pip-2.7 install mybarpackage
EDIT: pip changed its schema to use pipVERSION instead of pip-VERSION in version 1.5. You should use the following if you have pip >= 1.5:
$ pip2.6 install otherpackage
$ pip2.7 install mybarpackage

I installed python 2.7 with python brew. How do I install packages to work with it? I installed MySQLdb with synaptic, but I am unable to import it in python 2.7.
Switch to 2.7:
pythonbrew switch 2.7
Curl and run get-pip to get the correct version of pip for 2.7:
curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
python get-pip.py
This will install the version of pip for 2.7. Check it by doing:
pip --version
Turn off pythonbrew:
pythonbrew off
Check the version of pip again, and it should be using the one for your default Python:
pip --version
If all is good, then switch back to 2.7 in pythonbrew and install mysql-python for 2.7:
pythonbrew switch 2.7
pip install mysql-python
Check to see that it is installed for 2.7:
pip freeze
Pip freeze will give you a listing of all installed libraries for the current active version of Python.
You should try to install pip, which is a recursive acronym: Pip Installs Packages. This thread talks about installing it on windows, on Ubuntu I did sudo apt get install pip.
Ok, your problem is that "mysqldb" is not a python package. You need to use MySQLdb as a backend, or simply install sqlite3 and import that into Python, which is a module that mimics SQL. If you end up using an actual full-on database, like MySQLdb or PostgreSQL, you'll probably need to install SQLAlchemy, which is a Python module to interface with those.
You need to install a version of pip for each Python version. Do you have easy install available? If so you can do
easy_install-2.7 pip
Is there a specific reason that you are installing Python via home brew though? You do know that Ubuntu has as a package.
sudo apt-get install python2.7
Will give you a version of Python that is already nicely set up.
I also believe that you should be trying to install the Python package called mysql-python.
pip install mysql-python
MySQLDB is not a Python package. It's the actual database.
Agree with #leta-rogers. However, I didn't have to install pip separately. Installing python using pythonbrew installed pip (for python 2.7) for me as well:
pythonbrew install 2.7
pythonbrew switch 2.7
pip install mysql-python
