londiste3 error with import pkgloader

[shuwnyuantee]

My server is running Debian 7.8, with Postgresql-9.3 (9.3.6-1.pgdg70+1)

I want to use Londiste replication. I have installed the following Skytools package via apt-get install:

python-skytools3 3.2.6-3.pgdg70+1
skytools-modules-9.3 2.1.13-4.pgdg70+2
skytools3 3.2.6-3.pgdg70+1

After installation, upon running londiste command, or even service skytools3 start, I run into this error:

Traceback (most recent call last):
File "/usr/bin/scriptmgr3", line 48, in
import pkgloader
ImportError: No module named pkgloader

Trying locate pkgloader.py give me this:
/usr/lib/python2.7/site-packages/pkgloader.py

Any pointers here will be greatly appreciated, thanks!

What is the output of python -c 'import sys; print(sys.version); print(sys.path)'?

You might also consider building using setuptools instead.

Forgot to update here, I fixed my issue by running londiste3 this way:

PYTHONPATH=PYTHONPATH:/usr/lib/python2.7/site-packages/ londiste3 .......

@cdown Thanks for your quick reply :)

I have just faced the same error on Ubuntu 12.0.4, PostgreSQL 9.2 and Skytools3 3.2.6-3.pgdg12.4+1 when I was setting up a new server.

root@xxx:~# service skytools3 start
Traceback (most recent call last):
File "/usr/bin/scriptmgr3", line 48, in
import pkgloader
ImportError: No module named pkgloader

Please note that there were no such issues with the other 7 servers with Ubuntu 12.0.4, PostgreSQL 9.2 and Skytools3 3.1.5-1.pgdg12.4+1 that I setup several months ago.

I've found out that earlier skytools was installed under /usr/lib/pymodules/python2.7/

root@yyy:~# ls -l /usr/lib/pymodules/python2.7/
total 8
lrwxrwxrwx 1 root root 32 Oct 24 2014 pkgloader.py -> /usr/share/pyshared/pkgloader.py
-rw-r--r-- 1 root root 2647 Oct 24 2014 pkgloader.pyc
drwxr-xr-x 5 root root 4096 Oct 24 2014 skytools-3.0

root@xxx:~# python -c 'import sys; print(sys.version); print(sys.path)'
2.7.3 (default, Dec 18 2014, 19:10:20)
[GCC 4.6.3]
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/pymodules/python2.7']

and now it is installed under /usr/lib/python2.7/site-packages/

root@xxx:~# ls -l /usr/lib/python2.7/site-packages/
total 8
-rw-r--r-- 1 root root 2453 Nov 5 2014 pkgloader.py
drwxr-xr-x 5 root root 4096 May 26 11:18 skytools-3.0

that is not in the python path.

So my workaround is

root@yyy:# ln -s /usr/lib/python2.7/site-packages/pkgloader.py /usr/lib/python2.7/dist-packages/
root@yyy:# ln -s /usr/lib/python2.7/site-packages/skytools-3.0/ /usr/lib/python2.7/dist-packages/

I had a similar error though for completely different reasons. It looks like Skytools installed everything under /usr/local/local/.. (i.e. an extra local) which broke all the paths stuff.

This is running on:

• latest amazon linux ami (a centos variant)
• building from the github tar.gz using make

Am going to try and find out why it installed to a bad path.

[booleanbetrayal]

modifying PYTHONPATH seems like the easiest remediation, but the make install process should probably link appropriately like @grayhemp has implied.
