Python 2.7.9+ and 3.4+
Good news! Python 3.4 (released March 2014) and Python 2.7.9 (released December 2014) ship with Pip. This is the best feature of any Python release. It makes the community’s wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Node.js, Haskell, Perl, Go—almost every other contemporary language with a majority open-source community. Thank you, Python.
If you do find that pip is not available when using Python 3.4+ or Python 2.7.9+, simply execute e.g.:
py -3 -m ensurepip
Of course, that doesn’t mean Python packaging is problem solved. The experience remains frustrating. I discuss this in the Stack Overflow question Does Python have a package/module management system?.
And, alas for everyone using Python 2.7.8 or earlier (a sizable portion of the community). There’s no plan to ship Pip to you. Manual instructions follow.
Python 2 ≤ 2.7.8 and Python 3 ≤ 3.3
Flying in the face of its ‘batteries included’ motto, Python ships without a package manager. To make matters worse, Pip was—until recently—ironically difficult to install.
get-pip.py, being careful to save it as a
.py file rather than
.txt. Then, run it from the command prompt:
You possibly need an administrator command prompt to do this. Follow Start a Command Prompt as an Administrator (Microsoft TechNet).
This installs the pip package, which (in Windows) contains …\Scripts\pip.exe that path must be in PATH environment variable to use pip from the command line (see the second part of ‘Alternative Instructions’ for adding it to your PATH,
The official documentation tells users to install Pip and each of its dependencies from source. That’s tedious for the experienced and prohibitively difficult for newbies.
For our sake, Christoph Gohlke prepares Windows installers (
.msi) for popular Python packages. He builds installers for all Python versions, both 32 and 64 bit. You need to:
For me, this installed Pip at
pip.exe on your computer, then add its folder (for example,
C:\Python27\Scripts) to your path (Start / Edit environment variables). Now you should be able to run
pip from the command line. Try installing a package:
pip install httpie
There you go (hopefully)! Solutions for common problems are given below:
If you work in an office, you might be behind an HTTP proxy. If so, set the environment variables
https_proxy. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port http://username:[email protected]_url:port
If you’re really unlucky, your proxy might be a Microsoft NTLM proxy. Free software can’t cope. The only solution is to install a free software friendly proxy that forwards to the nasty proxy. http://cntlm.sourceforge.net/
Unable to find vcvarsall.bat
Python modules can be partly written in C or C++. Pip tries to compile from source. If you don’t have a C/C++ compiler installed and configured, you’ll see this cryptic error message.
Error: Unable to find vcvarsall.bat
Often though it’s easier to check Christoph’s site for your package.
— Outdated — use distribute, not setuptools as described here. —
— Outdated #2 — use setuptools as distribute is deprecated.
As you mentioned pip doesn’t include an independent installer, but you can install it with its predecessor easy_install.
- Download the last pip version from here: http://pypi.python.org/pypi/pip#downloads
- Uncompress it
- Download the last easy installer for Windows: (download the .exe at the bottom of http://pypi.python.org/pypi/setuptools ). Install it.
- copy the uncompressed pip folder content into
C:\Python2x\folder (don’t copy the whole folder into it, just the content), because python command doesn’t work outside
C:\Python2xfolder and then run:
python setup.py install
- Add your python
C:\Python2x\Scriptsto the path
You are done.
Now you can use
pip install package to easily install packages as in Linux 🙂
1) If you have installed Python 3.4 or later, pip is included with Python and should already be working on your system.
2) If you are running a version below Python 3.4 or if pip was not installed with Python 3.4 for some reason, then you’d probably use pip’s official installation script
get-pip.py. The pip installer now grabs setuptools for you, and works regardless of architecture (32-bit or 64-bit).
The installation instructions are detailed here and involve:
To install or upgrade pip, securely download get-pip.py.
Then run the following (which may require administrator access):
To upgrade an existing setuptools (or distribute), run
pip install -U setuptools
I’ll leave the two sets of old instructions below for posterity.
For Windows editions of the 64 bit variety – 64-bit Windows + Python used to require a separate installation method due to ez_setup, but I’ve tested the new distribute method on 64-bit Windows running 32-bit Python and 64-bit Python, and you can now use the same method for all versions of Windows/Python 2.7X:
OLD Method 2 using distribute:
- Download distribute – I threw mine in
C:\Python27\Scripts(feel free to create a
Scriptsdirectory if it doesn’t exist.
- Open up a command prompt (on Windows you should check out conemu2 if you don’t use PowerShell) and change (
cd) to the directory you’ve downloaded
- Run distribute_setup:
python distribute_setup.py(This will not work if your python installation directory is not added to your path – go here for help)
- Change the current directory to the
Scriptsdirectory for your Python installation (
C:\Python27\Scripts) or add that directory, as well as the Python base installation directory to your %PATH% environment variable.
- Install pip using the newly installed setuptools:
The last step will not work unless you’re either in the directory
easy_install.exe is located in (C:\Python27\Scripts would be the default for Python 2.7), or you have that directory added to your path.
OLD Method 1 using ez_setup:
Download ez_setup.py and run it; it will download the appropriate .egg file and install it for you. (Currently, the provided .exe installer does not support 64-bit versions of Python for Windows, due to a distutils installer compatibility issue.
After this, you may continue with:
c:\Python2x\Scriptsto the Windows path (replace the
Python2xwith the actual version number you have installed)
- Open a new (!) DOS prompt. From there run
