pycopg2 build problems

[devaru]

Hi,

I'm trying to install psycopg2 on my system. I followed the
instruction in INSTALL file and gave the command
python setup.py build
running build
running build_py
running build_ext
error: No such file or directory

Where is the file or directory missing. Any help is appreciated.

Try asking on the psycopg2 mailing list.


Good luck

I ran into this some days ago. The problem is not related to the
distribution you downloaded, but to missing information about PostgreSQL
itself.

IIRC the file in question is "/usr/bin/pg_config". The file is probably packaged
in some lib*-dev package on your distribution.

--- Debian example ---
$ apt-file search /usr/bin/pg_config
libpq-dev: /usr/bin/pg_config
--- snip ---

thanks for all the fish

Just wanted to note that libpq-dev is a dependency of
postgresql-server-dev-8.4 on squeeze. So you *might* want to consider
installing that instead of libpq-dev.

I ran into this some days ago. The problem is not related to the

itself.

IIRC the file in question is "/usr/bin/pg_config". The file is

That's the most common install problem with psycopg2 -- setup.py can't
find (or execute) pg_config which it needs to decide how to talk to
Postgres. I remember it giving a different (and more descriptive)
error but I haven't used psycopg2 recently.

To the OP: if executing pg_config fails from the same command line in
which you're running setup.py, then Wolodja is absolutely correct. You
need to get pg_config on your path somewhere, or there might be an
environment variable you can set to tell setup where to find it if you
don't want it in your path.

Good luck
Philip

Thank you all.

Yes, as Philip and Wolodja have said, we need pg_config in the PATH
variable for psycopg2 to build.
Then I ran into a problem where I had to install the dependency
package python-devel.
Now psycopg2 installed fine.
