Installing packages is simple:
C:\> pypm install pyramid
This command will download pyramid and its depdendencies automatically. Unless the -g option is specified, packages are not installed into the ActivePython installation directory. Instead, PyPM follows the PEP 370 specification and installs packages by default in ~/.local on Unix and Mac and %APPDATA%\Python on Windows; and the Python interpreter automatically picks up the local packages. To find where the package was installed, use the show or files command.
ex :: python -g install pybedtools
ex :: python -g install pybedtools
