I'm trying to install the macaulay2 package and I'm getting an error which i can't seem to figure out. Please excuse my newbitude.


sage: install_package(macaulay2)

TypeError Traceback (most recent call last)

/opt/sage-4.6.1-linux-64bit-ubuntu_10.04.1_lts-x86_64-Linux/data/extcode/macaulay2/user/<ipython console=""> in <module>()

TypeError: expected a character buffer object


What does this mean? What do I need to do to fix it?

I'm retarded again. The correct input was the string

'macaulay2' rather than just macaulay2 so the correct command is actually install_package('macaulay2')
