Re: Doing the basic tutorial, MySQL-python problems.

No, python-mysqldb-dbg is not related to the problem.  ("dbg" is an abbreviation for debug, while "devel" or "dev" stands for I want to do software development to work with the main package" such as building the python connectory, the operation that got you your error message.

When you pip install python-msqldb, that only installs the python connector for MySQL (and if you do it with synaptic, probably only for the system python).  You also have to install MySQL itself (with no "python-" in front of it), and it is that package that might have a -dev version.  You install MySQL and possibley MySQL-dev (or however they're spelled, I don't have a debian based system handy to check) using synaptic (or apt or dselectd or yum or rpm).  Then you do whatever you were doing (a pip install of something?) that got the original error, because it was trying to install MySQL-python (in your virtualenv, I presume).

My rule of thumb is to never install with synaptic (etc.) that which you can install with pip, but there are a bunch of things that you can't install with pip, such as MySQL itself.

I found a python-mysqldb-dbg in Synaptic, would that be it? Failing that, what would be the, umm, Pythonic way to reinstall MySQL?

I'm also confused by the various names - in Synaptic I've got python-mysqldb installed, but there's also MySQL-Python, which I can't tell if that's the same package or something entirely different... I'm drowning in new software and concepts at the moment. Argh.

If it's like PostgreSQL, it should have been installed somewhere when you installed MySQL.  But if you installed it using an O/S package manager, rather than from source, the O/S vender may have "helpfully" excluded bits they don't think you need.  Often this will require additionally installing a "-devel" (RPM based systems) or "-dev" (deb based systems) of the MySQL package.

I ran:

sudo find / -name 'mysql_config'

and it didn't find it. Using the same search, I did find something from my home dir, so it seems that it's not actually installed, or rather.. argh. I've attempted every "this is how to install MySQL-python method I could find on the web, and it either fails to install or says it's already installed, but the damn server can't see it.

I've switched it to a sqlite database for now, but this is pissing me off...

If the program mysql_config is installed on your box, it may be installed in a directory that is not on your path.  If you can find it on your box (try the locate and find commands), you can add the directory to your PATH by hand before running pip (or easy_install).  It only needs to be there for the runnings of pip that instiall or update MySQL-python so you don't need to add the directory permanently.  (An alternative is a symbolic link to it in some directory that is on your path, such as maybe /usr/local/bin - though this is slightly less certain to work, depending on how clever mysql_config is - I don't use MySQL, so I don't know for sure.)

I'm trying to do the "Writing Your first Django App" tutorial, and Django can't see MySQL-python, though it is installed globally.

I'm not sure if this is a virtualenv problem or what.
