Error installing matplotlib 0.98.5

_Mauro_Cavalcanti · December 15, 2008, 12:25am

Dear ALL,

I have experienced a strange problem when installing Matplotlib 0.98.5
using Easy_Install under Ubuntu Hardy. I receive a message like this:
"error: lib/matplotlib/mpl-data/matplotlib.conf.template: No such file
or directory " (etc.). I then tried sudo aptitude install
python-matplotlib, that gives no errors, but also do not install the
new version. In the end, I had to install from the source (and this,
of course, worked well).

Does anyone else have seen this problem (and, if so, has a solution to it)?

Thanks in advance.

With best regards,

···

Could you please post the entire shell session -- the command you run
and all the output?

Thanks,

I can replicate it too, and I think I am getting some insight into
what is going on and it may point to a distutils and/or easy_install
bug (but one we can work around).

The file in question is matplotlib.conf.template, which exists in
lib/matplotlib/mpl-data. There is a symlink in doc/mpl_data which
points to lib/matplotlib/mpl-data. Eg in the mpl src tree::

    jdhunter@...2404...:mpl> ls -ld lib/matplotlib/mpl-data/ doc/mpl_data
    lrwxrwxrwx 1 jdhunter jdhunter 27 Jun 2 2008 doc/mpl_data ->
../lib/matplotlib/mpl-data/
    drwxrwxr-x 6 jdhunter jdhunter 4096 Dec 10 13:09 lib/matplotlib/mpl-data/

Now create the sdist::

    jdhunter@...2404...:mpl> python setup.py sdist > sdist.out
    jdhunter@...2404...:mpl> grep matplotlib.conf.template sdist.out
    hard linking doc/mpl_data/matplotlib.conf.template ->
matplotlib-0.98.5/doc/mpl_data
    hard linking lib/matplotlib/mpl-data/matplotlib.conf.template ->
matplotlib-0.98.5/lib/matplotlib/mpl-data

If we create an sdist, the symlink is backwards: the tarball says
lib/matplotlib/mpl-data/matplotlib.conf.template links to
doc/mpl_data/matplotlib.conf.template and has zero content

jdhunter@...2404...:tmp> tar tvfz matplotlib-0.98.5.tar.gz |grep
matplotlib.conf.template
-rw-r--r-- cmoad/staff 13838 2008-12-09 17:53
matplotlib-0.98.5/doc/mpl_data/matplotlib.conf.templatehrw-r--r--
cmoad/staff 0 2008-12-09 17:53
matplotlib-0.98.5/lib/matplotlib/mpl-data/matplotlib.conf.template
link to matplotlib-0.98.5/doc/mpl_data/matplotlib.conf.template

If you unpack the tarball using a standard incantation, a copy is made::

    jdhunter@...2404...:tmp> tar xfz matplotlib-0.98.5.tar.gz
    jdhunter@...2404...:tmp> cd matplotlib-0.98.5/
    jdhunter@...2404...:matplotlib-0.98.5> ls -ld
doc/mpl_data/matplotlib.conf.template
lib/matplotlib/mpl-data/matplotlib.conf.template
    -rw-r--r-- 2 jdhunter jdhunter 13838 Dec 9 17:53
doc/mpl_data/matplotlib.conf.template
    -rw-r--r-- 2 jdhunter jdhunter 13838 Dec 9 17:53
lib/matplotlib/mpl-data/matplotlib.conf.template

I think what may be happening is that setuptools are reading the
tarball using the python tarfile reader and the link is getting
botched. However, I can read the "missing" file using tarfile::

In [17]: import tarfile

In [18]: t = tarfile.open('dist/matplotlib-0.98.5.tar.gz')

In [19]: o =
t.extractfile('matplotlib-0.98.5/lib/matplotlib/mpl-data/matplotlib.conf')

In [20]: s = o.read()

In [21]: print s[:80]
# MPLConfig - plaintext (in .conf format)

# This is a sample matplotlib configu

So I am not sure exactly what is going wrong but I think broken
handling of the link is playing a role. I will probably work around
this by removing the links and making hard copies myself before
building the sdist and eggs, unless I hear something more intelligent
from someone or come up with something better.
