python - setup.py 包和 unicode_literals

Question

我已经在 Py2.7 中创建了一个包，我正在尝试使其与 Py3 兼容。问题是如果我在

__init__.py

导入构建返回这个错误

error in daysgrounded setup command: package_data must be a dictionary mapping
package names to lists of wildcard patterns

我读过 PEP，但我不明白它与像这样的字典有什么关系

__pkgdata__

谁能帮忙？

使用 unicode_literals 与对输入文件中的每个字符串文字使用 u'...' 相同，这意味着在您的 __init__.py 指定

__pkgdata__ = {'daysgrounded': ['*.txt']}

其实和

是一样的

__pkgdata__ = {u'daysgrounded': [u'*.txt']}

对于 python2，setuptools 在这里不期望 unicode 而是 str，所以它失败了。

因为看起来你在 __init__.py 中的字符串文字中没有使用任何 unicode 字符，只是简单的 ascii，所以你可以简单地删除 unicode_literals 导入.如果您真的在文件中的某个地方使用了 unicode 文字，但您的帖子中没有显示，请在那里使用明确的 unicode 文字。
