failed to load icu

[fem]

So I trie to install the git version of calibre and wanted to setup a development environment. I issued following command (as described in the INSTALL file)

sudo python setup.py develop

which fails with following error.

Traceback (most recent call last):
  File "setup.py", line 99, in <module>
    sys.exit(main())
  File "setup.py", line 85, in main
    command.run_all(opts)

RuntimeError: Failed to load icu with error: No module named icu
/home/billiau/git/calibre/src/calibre/ptempfile.py:27: RuntimeWarning: Parent module 'calibre' not found while handling absolute import
  import shutil

if I just

dpkg --get-selections | grep libicu

I get this list:

libicu-dev					install
libicu44					deinstall
libicu48:amd64					install
libicu4j-4.4-java				install
libicu4j-java					install

I'm running ubuntu 13.10

Is there something I'm missing here? Do I explictely need libicu44?

The first thing you need to do is uninstall your distro version of calibre, which will be too old to run current development code.

Install the calibre binary from the calibre website, http://calibre-ebook.com/download_linux then try to setup the development environment.

I got the same result.

I purged calibre from my system and then went ahead and did this:

sudo -v && wget -nv -O- https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

Cloned a calibre fork from github and tried

sudo python setup.py develop

But I still get the icu error.

[kovidgoyal]

To setup a development environment, you need to be following these instructions: http://manual.calibre-ebook.com/develop.html

Use the instriuctions for linux with a binary install

Aha, ok! It works.

I got the protocol all wrong! Sorry for all the confusion.

I now installed the binary, cloned from git and then instead of trying to setup I _only_ set the CALIBRE_DEVELOP_FROM. And it works

I have the same question, but I dont know how to chek it !
