无法在python 2.7上安装matplotlib

Question

When I tried to install matplotlib 2.2.4 on centos 7.4 , and I run setup.py install , The erros is

"error: can't copy 'lib/matplotlib/backends/web_backend/jquery-ui-1.12.1': doesn't exist or not a regular file."

But the lib/matplotlib/backends/web_backend/jquery-ui-1.12.1 exists.

So who can tell me what to do to fix it.

Answer 1

This error is happening when the package_data glob happens to match a directory. You need to re-write setup.py and change the name of your package to fix it.

Package_data assumes every name matched in the glob is a file, it confuses files and directories.

Modify your setup.py as below:

from distutils.core import setup

setup(name='xxx',
      version='0.1',

      packages=[
          'package',
      ],
      package_data={
          'package': [
              '*.dat',
              'dir/*'
      ],
  },
 )

You just need to change the name of the package_data . If the package name is * just add .dat after it.
