I would highly recommend grabbing the latest Raspbian image and re-doing your SD card. This includes RPi.GPIO and saves you having to install it manually.

[sompor9]

I use new version image. but have not include GPIO Library.

new version is 2012-10-28-wheezy-raspbian.zip

Try

Code: Select all

apt-get install python-rpi.gpio

better sudo it:

Code: Select all

$ sudo apt-get install python-rpi.gpio

I had mentionned on my blog ( http://raspberry-python.blogspot.com/20 ... -dash.html ) that Pypi didn't have but 0.3 and 0.4.1a was the latest. Well, pypi.python.org now has the latest, so it can be installed in a native Python way, instead of through the OS apt-get.

This way:

Code: Select all

$ sudo easy_install RPi.GPIO

Of course you have to install easy_install (instructions for that on the link I put above), but you cant do python and not have easy_install on your system.

$ sudo apt-get install python-rpi.gpio

Well I often forget as so much I do on Pi needs root I logion as root

[keybeeper]

Do not make a habit of logging-in as root. One day you will regret it,

[techpaul]

Considering 99% of my work is not net related and limited to specific things that have to be done by sudo or being logged on as root, for a few hours a day at most, I doubt it.

System is not one of my main systems and I run with sacrificial SD cards, my data that is limited is saved on USB. pen drive. spent too many years having to administer various systems including *nix systems, with much more data and potential problems than a simple Pi

Many learners will be reading this thread. I repeat, it is a bad idea to log in as root. If you are experienced and know what you are doing, fine, take the risk.

Linux assumes that you really mean what you ask it to do and you know what you are doing. Often you get no second chance. Unless you have a backup you could end up losing many hours, if not days of work.

If you wish to log in as root, first make very sure your work is backed up.

If the command is potentially dangerous you will usually get a refusal of some kind, unless you are logged-in as root that is.

It is so quick to edit the command line to put sudo at the front if necessary.

If you are inexperienced, never log in as root.
