#+TITLE: How to locally install python

#+AUTHOR: phdenzel

  On a server or shared machine, you might want to install stuff locally, i.e. in your home directory.

  I often get asked how I installed python this way.

  This is what I did (more or less):

*** Installing in ~/local/python

    First, we need to create the directories, where python has to be installed.

    #+BEGIN_SRC shell

      mkdir -p ~/local/python/2.7

    #+END_SRC

    

    Then go to the created directories and download the python source code

    (I used 2.7.something, however if you're starting out completely new, I recommend 3.6.5).

    #+BEGIN_SRC shell

      cd ~/local/python

      wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz

    #+END_SRC

    

    Unpack it... do you remember the tar flags?

    #+BEGIN_SRC shell

      tar zxfv Python-2.7.15.tgz

    #+END_SRC

    Make the directories safe from outside influence

    #+BEGIN_SRC shell

      find ~/local/python -type d | xargs chmod 0755

    #+END_SRC

    

    ... and finally install in your local directory with

    #+BEGIN_SRC shell

      cd Python-2.7.15

      ./configure --prefix=$HOME/local/python/2.7

      make && make install

    #+END_SRC

    Make sure to include the ~--prefix~ flag, since this is where the output of ~make~ is installed.

    On UNIX machines this is by default in ~/usr/local~.

    

    If you've received an error message about the C compiler, you might have to change the second line to

    #+BEGIN_SRC shell

      CC=gcc ./configure --prefix=$HOME/local/python/2.7

    #+END_SRC

    or a similar compiler of your choice (that works).

    On macOS (if you decide to install ~python~ from source code) many dependencies are very outdated!

    That's why if you installed another Tcl/Tk version (~8.6~) for example you can specify additional flags

    #+BEGIN_SRC shell

      ./configure --prefix=$HOME/local/python/2.7 \

                  --with-tcltk-includes='-I/Library/Frameworks/Tcl.framework/Headers -I/Library/Frameworks/Tk.framework/Headers' \

                  --with-tcltk-libs='/Library/Frameworks/Tcl.framework/Versions/8.6/Tcl /Library/Frameworks/Tk.framework/Versions/8.6/Tk'

      make && make install

    #+END_SRC

    If you want to build a framework-based python on macOS use

    #+BEGIN_SRC shell

      ./configure --prefix=$HOME/local/python/2.7 \

                  --enable-framework=$HOME/local/python/2.7 \

                  --with-tcltk-includes='-I/Library/Frameworks/Tcl.framework/Headers -I/Library/Frameworks/Tk.framework/Headers' \

                  --with-tcltk-libs='/Library/Frameworks/Tcl.framework/Versions/8.6/Tcl /Library/Frameworks/Tk.framework/Versions/8.6/Tk'

      make && make install

    #+END_SRC

    On linux, Tcl can easily be installed with ~sudo apt-get install tcl8.6 tcl8.6-dev libtcl8.6 tk8.6 tk8.6-dev libtk8.6~.

    The additional flags then are

    

    #+BEGIN_SRC shell

      ./configure --prefix=$HOME/local/python/2.7 \

                  --with-tcltk-includes='-I/usr/include/tcl8.6 -I/usr/include/tk8.6' \

                  --with-tcltk-libs='/usr/lib/*-linux-gnu/libtcl8.6.so /usr/lib/*-linux-gnu/libtk8.6.so'

      make && make install

    #+END_SRC

    On some linux machines, it can happen that ~lib-dynload~ is installed in a non-default location.

    To easily fix this, I found that the following command usually helps

    #+BEGIN_SRC shell

      cp -r $HOME/local/python/2.7/lib64/python2.7/lib-dynload $HOME/local/python/2.7/lib/python2.7/

    #+END_SRC

*** Defining path variables

    Now that we have locally installed python, we have to define the path to the local library in our ~.bash_profile~.

    #+BEGIN_SRC shell

      export PATH=$HOME/local/python/2.7/bin:$PATH

      export PYTHONPATH=$HOME/local/python/2.7

    #+END_SRC

    

    To test if it worked type

    #+BEGIN_SRC shell

      source ~/.bash_profile

      which python

    #+END_SRC

    or something similar (like ~.bashrc~).

    If the output of ~which~ includes ~/local/python/~ it worked!

*** Setting up pip

    I use pip to install all my python libraries.

    Since python is already installed, it is relatively painless to install ~pip~.

    #+BEGIN_SRC shell :export

    wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py -O - | python - --user

    #+END_SRC

    

    This downloads and installs ~pip~ locally in ~$HOME/.local/bin~.

    If you installed python as a framework, the above ~pip~ install command will automatically 

    install ~pip~ in ~$HOME/Library/Python/2.7/~.

    However, if you want to install it still in ~$HOME/.local/~ use

    #+BEGIN_SRC shell :export

    wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py -O - | python - --prefix=$HOME/.local/

    #+END_SRC

    Now, we just have to update the PATH in your ~.bash_profile~ and you're good to go...

    #+BEGIN_SRC shell

      export PATH=$HOME/.local/bin:$PATH

    #+END_SRC

    

    Again, test it with

    #+BEGIN_SRC shell

      source ~/.bash_profile

      which pip

    #+END_SRC
