On my laptop I like to keep my Python packages installed in my account. This way I avoid overwriting something the system may need. For that to work I need to tell Python where to find the packages, which is done by setting a few Python environment variables.

For other ways of having local versions of Python, see:

Create the the site-packages folder with

If you are getting this in gdb on macOS while trying to run a program:

Unable to find Mach task port for process-id 57573: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

Open Keychain Access
In menu, open Keychain Access > Certificate Assistant > Create a certificate
Give it a name (e.g. gdbc)

Files

First things first, I want to use ag to search through my project files. Coming from fzf, I like to have two bindings for this -- one that respects my projects .gitignore and one that does not. The latter is helpful if I want to examine a built file or look at a node_module dependency while working on my js project.

I use an alias for file_rec source to toggle the -u flag on ag. Now, <C-P> searches in my git files, and <C-O> searches everything.

" denite file search (c-p uses gitignore, c-o looks at everything)
map <C-P> :DeniteProjectDir -buffer-name=git -direction=top file_rec/git<CR>
map  :DeniteProjectDir -buffer-name=files -direction=top file_rec

	First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py
	$ cd <download location>
	$ sudo -H python ./get-pip.py

	Installing pip also installs Python3
	To run Python3
	$ python3

	Install pip3 by just executing the same file as in the step above, but this time using Python3
	$ sudo -H python3 ./get-pip.py
