How to Use Python2.7 Pip Instead of Default Pip

how to use python2.7 pip instead of default pip

There should be a binary called "pip2.7" installed at some location included within your $PATH variable.

You can find that out by typing

which pip2.7

This should print something like '/usr/local/bin/pip2.7' to your stdout. If it does not print anything like this, it is not installed. In that case, install it by running

$ wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
$ sudo python2.7 get-pip.py

Now, you should be all set, and

which pip2.7

should return the correct output.

Dealing with multiple Python versions and PIP?

The current recommendation is to use python -m pip, where python is the version of Python you would like to use. This is the recommendation because it works across all versions of Python, and in all forms of virtualenv. For example:

# The system default python:
$ python -m pip install fish

# A virtualenv's python:
$ .env/bin/python -m pip install fish

# A specific version of python:
$ python-3.6 -m pip install fish

Previous answer, left for posterity:

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

Can pip (python2) and pip3 (python3) coexist?

Every Python should have own pip because every Python may use different version of the same module and every Python installs modules in different folder.

You can use Python2 to reinstall module pip for Python2 and it should create file with correct name pip

python -m pip install -U --force pip

You should also have pip, pip2, pip2.7, pip3, pip3.5.

You can even have pip3.6, pip3.7 at the same time.

If you write in console pip and press tab and it should show you all programs which start with word pip

You can find full path for pip with

which pip 

and you can open it in text editor to see if it is python's script.

Different pip have different first line - ie. #!/usr/bin/python or #!/usr/bin/python3.5.

Rest code should be the same for all versions.

Pip install - Python 2.7 - Windows 7

For New versions

Older versions of python may not have pip installed and get-pip will throw errors. Please update your python (2.7.15 as of Aug 12, 2018).

All current versions have an option to install pip and add it to the path.

Steps:

1. Open Powershell as admin. (win+x then a)
2. Type python -m pip install <package>.

If python is not in PATH, it'll throw an error saying unrecognized cmd. To fix, simply add it to the path as mentioned below[1].

[OLD Answer]

Python 2.7 must be having pip pre-installed.

Try installing your package by:

1. Open cmd as admin. (win+x then a)
2. Go to scripts folder: C:\Python27\Scripts
3. Type pip install "package name" .

Note: Else reinstall python: https://www.python.org/downloads/

[1] Also note: You must be in C:\Python27\Scripts in order to use pip command, Else add it to your path by typing:
[Environment]::SetEnvironmentVariable("Path","$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")

How can I install pip for Python2.7 in Ubuntu 20.04

Pip for Python 2 is not included in the Ubuntu 20.04 repositories.

Try this guide which suggests to fetch a Python 2.7 compatible get_pip.py and use that to bootstrap pip.

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py

Using pip on Windows installed with both python 2.7 and 3.5

You will have to use the absolute path of pip.

E.g: if I installed python 3 to C:\python35, I would use:
C:\> python35\Scripts\pip.exe install packagename

Or if you're on linux, use pip3 install packagename

If you don't specify a full path, it will use whichever pip is in your path.
