Installing plyvel on Ubuntu 12.04

[rendykstan]

Hi,

I ran into an issue with installing plyvel on my server running Ubuntu 12.04, I received this error.

$python -c 'import plyvel'

Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/plyvel/init.py", line 6, in from ._plyvel import ( ImportError: /usr/local/lib/python2.7/dist-packages/plyvel/_plyvel.so: undefined symbol: _ZN6snappy13RawUncompressEPKcmPc

I have these shared libraries install but it is still not working for me.

libleveldb1 (.deb for 12.10) libsnappy1 (apt-get), libleveldb-dev (apt-get), leveldb-doc (apt-get)

I am not installing plyvel on virtualenv on my server. Any know issue with plyvel install on the native python 2.7.3?

Are the headers and the installed library the same version? What is the output of 'ldd _plyvel.so'?

Hi @rendykstan

I frequently run through this error whenever I've mixed in some way packages versions, or have both manually installed and system-packages for leveldb.

Generally I just

sudo rm -rf /usr/local/lib/libleveldb*
sudo rm -rf /usr/local/lib/libsnappy*
sudo apt-get remove --purge libleveldb1 libleveldb-dev libsnappy1 libsnappy-dev
sudo apt-get install libleveldb1 libleveldb-dev

And everything just works fine.

You might find usefull to use my repository for leveldb related packages, which will provide you functional unified versions: See Elevator Readme

Hi @oleiade

Thank you for the tip. I followed your instructions and did this.

$pico /etc/apt/sources.list
deb http://deb.oleiade.com/debian oneiric main
$apt-get update

ran into problematic key issue. And the solutions is as follows.

Take the key you have problem with, for example E635A714505A2DD1, take the last 8 symbols (in this case - 505A2DD1) and run the following in the terminal:

Code:
$gpg --keyserver keyserver.ubuntu.com --recv 505A2DD1
$gpg --export --armor 505A2DD1 | sudo apt-key add -
$apt-get update

$apt-get install libleveldb1 libleveldb-dev
$pip install plyvel
$python -c 'import plyvel'
