Python distutils错误：“ [目录] ...不存在或不是常规文件” [英] Python distutils error: "[directory]... doesn't exist or not a regular file"

问题描述

让我们采用以下项目布局：

Let's take the following project layout:

$ ls -R .
.:
package  setup.py

./package:
__init__.py  dir  file.dat  module.py

./package/dir:
tool1.dat  tool2.dat

以下内容为 setup.py ：

$ cat setup.py 
from distutils.core import setup


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

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

如您所见，我想包括所有非- package / 和 package / dir / 目录中的Python文件。但是，运行 setup.py install 会引发以下错误：

As you can see, I want to include all non-Python files in package/ and package/dir/ directories. However, running setup.py install would raise the following error:

$ python setup.py install
running install
running build
running build_py
creating build
creating build/lib
creating build/lib/package
copying package/module.py -> build/lib/package
copying package/__init__.py -> build/lib/package
error: can't copy 'package/dir': doesn't exist or not a regular file

有什么用？

推荐答案

在您的 package_data ，您的'*'全局名称将匹配 package / dir 本身，并尝试将该目录复制为文件，导致失败。找到与目录 package / dir 不匹配的全局名称，按照以下几行重写您的 setup.py ：

In your package_data, your '*' glob will match package/dir itself, and try to copy that dir as a file, resulting in a failure. Find a glob that won't match the directory package/dir, rewriting your setup.py along these lines:

from distutils.core import setup

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

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

以您的示例为例，这只是将'*'更改为'*。dat'，尽管您可能需要进一步优化glob，但只需确保它与'dir'

Given your example, that's just changing '*' to '*.dat', although you'd probably need to refine your glob more than that, just ensure it won't match 'dir'
