If you unpack pip.exe or pip3.exe regardless it's python 2.x or 3.x, inside is the SAME single file _main_.py: # -*- coding: utf-8 -*. Warning: Some parameters as simple -help may cause python interpreter to stop.Ĭuriosity: By using pip.exe you actually use python interpreter and pip module anyway.
#PIP INSTALL THONNY RUN INSTALL#
Note: When you install from list in file with -r / -requirement parameter you do NOT need open() function. If you want to stop installing other packages if any installation fails, use it in one single pip.main() call: import pip If you need to update every installed package, use following: import pipįor i in pip.get_installed_distributions(): # -upgrade to install or update existing packages If you want to use pip inside the Python interpreter, try this: import pip Instead you may use generator freeze like this: from pip._ import freeze
v.18 get_installed_distributions() has been removed. UPDATE: Since pip version 10.x there is no more get_installed_distributions() or main method under import pip instead use import pip._internal as pip. if you're building own GUI package manager with alternative resourcess like įollowing soulution is OUT OF DATE, instead of downvoting suggest updates. As suggested correct way of installing a package via pip is using separate process since pip may cause closing a thread or may require a restart of interpreter to load new installed package so this is the right way of using the API: subprocess.check_call() but since Python allows to access internal API and you know what you're using the API for you may want to use internal API anyway eg.
