pkg故障排除_未找到resources.DistributionNotFound

Question

为什么this simple program在运行时会导致pkg_resources.DistributionNotFound错误，我们如何修复它？在

#setup.py
from setuptools import setup

setup(name='my_project',
    version='0.1.0',
    packages=['my_project'],
    entry_points={
        'console_scripts': [
            'my_project = my_project.__main__:main'
        ]
     },
)

一。在

^{pr2}$

构建：python setup.py install --root=target --prefix=usr
运行：.\target\usr\Scripts\my_project.exe

结果

Traceback (most recent call last):
  File "D:\code-maphew\scraps\bug-dist-not-found\target\usr\Scripts\my_project-script.py", line 6, in <module>
    from pkg_resources import load_entry_point

这个Q类似于pkg_resources.DistributionNotFound when using a module installed from a bdist_rpm，但不是构建RPM。使用--prefix解决了这个问题。这对我没用。我在Windows10、LinuxMint和Debian上复制了相同的问题。在

Answer 1

我也有同样的问题。问题是代码在一台计算机上工作，而在另一台计算机上不工作。我也在用我造的轮子。总之，我找到的解决方案是升级pip和我的包。例如

pip install  upgrade pip path/to/my_package

它重新安装了pip和我的包，然后入口点开始工作了。在
