Install PIP for Pythonista 3.x

README.md

Usage

1. run install pip.py, follow instructions

• edit pip config that placed in the local root
• edit your pythonista_startup.py, add PIP_CONFIG_FILE env

2. reboot Pythonista
3. run run.py, then type show pip or freeze

That's all. Now you can (un)install packages, upgrade pip, whatever.

• ⚠️ Currently python-only non-binary packages are supported.

Also I recomend to make shortcut btn to run pip.py.

Screenshots:

def run(args):
	try:
		output = int(main(args))
		if output != 0:
			sys.exit(output)

			sys.exit(103)
		run(query.split())

Couple of small fixes/improvements for this:

• Install pip and set packages location in pip.conf with an absolute path for site-packages-3 (otherwise installs can be relative to install.py and run.py file locations)
• Add missing import editor in install.py
• Filter out “pip” or “pip3” strings from first argument in run.py for easier pasting of pip commands
