# so I include a very quick note that it's used for SSH. # The name fabric doesn't really convey to the end user why the module is needed, # I like to have my messages timestamped so I can get an idea of how long they take. Here are some usage examples: from datetime import datetime Log("Installing " + moduleName + notes + " Library for Python")Ĭall() If moduleName not in for tuple_ in iter_modules()]: """ Installs a Python library using pip, if it isn't already installed.
#Python download module install
# Check if pip is installed, and install it if it isn't.ĭef installIfNeeded(moduleName, nameOnPip=None, notes="", log=print): PipPath = join(prefix, 'Scripts', 'pip.exe') # On OS X, I seem to have pip at /usr/local/bin/pip? # tested and works on Windows, but will likely need tweaking for other OS's. # Generate the path to where pip is or will be installed. This returns the path to the pip executable, installing it if necessary. Pip is the standard package manager for Python. Log("Installing pip, the standard Python Package Manager, first")

This code should pretty cleanly do just that. It's included in the default installation, but older versions may need toĭownload and install it. and I think it'll work in version 3.0+ but I've never tried it.Īlso, as I note in the comments of my getPip function, I don't think that particular function will work under OS X. it would probably work in older versions if I didn't want to handle print as a function. It actually checks whether the module is installed rather than relying on ImportError (it just looks cleaner, in my opinion, to handle this with an if rather than a try/ except). Here's the solution I put together which I call pyInstall.py.
