[Matplotlib-users] use matplotlib in a cgi script

[frank h. <fra...@gm...>]

Hello,
I am trying to use matplotlib in a cgi script and I always get an error

the following script is the simplest script that reproduces the error

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
#!/sw/bin/python2.4

from pylab import *
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

and the error is always:

    from matplotlib.ticker import *
  File "/sw/lib/python2.4/site-packages/matplotlib/__init__.py", line 862, =

    raise RuntimeError("'%s' is not a writable dir; you must set

RuntimeError: '/Library/WebServer' is not a writable dir; you must set
