Configuring Python's installation Environment on Mac Miscellaneous notes

The Python packages are now installed via PIP.

So a very important step is to configure the PIP installation source

vi ~/.pip/pip.conf[global]index-url = http://pypi.douban.com/simple

In addition, the Python package on Mac has two locations

/system/library/frameworks/python.framework/versions/2.7/extras/lib/python
/library/python/2.7/site-Packages

First position is preferred.

Ways to manually remove packages

In the top two locations, locate the installation package, and then add the RM to it.

PIP installs additional packages

Install somepackage             Install somepackage==1.0. 4 Install ' somepackage>=1.0.4 ' # minimum version           

PIP Updates Other Packages

Install --upgrade somepackage

Pip Uninstalls other packages

Pip Uninstall Somepackage

PIP lists the installed packages

$ pip listdocutils (0.9. 1 ) Jinja2 (2.6) pygments (1.5) Sphinx (1.1. 2)
