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. Show If you do find that pip is not available when using Python 3.4+ or Python 2.7.9+, simply execute e.g.:
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 ≤ 3.3Flying 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. Official instructionsPer https://pip.pypa.io/en/stable/installing/#do-i-need-to-install-pip: Download
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, Alternative instructionsThe 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

For me, this installed Pip at
There you go (hopefully)! Solutions for common problems are given below: Proxy problemsIf you work in an office, you might be behind an HTTP proxy. If so, set the environment variables
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.batPython 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.
You can fix that by installing a C++ compiler such as MinGW or Visual C++. Microsoft actually ships one specifically for use with Python. Or try Microsoft Visual C++ Compiler for Python 2.7. Often though it's easier to check Christoph's site for your package. Edit this page Toggle table of contents sidebar Usually, pip is automatically installed if you are:
