为什么 this simple program 在运行时会导致 pkg_resources.DistributionNotFound
错误,我们该如何解决?
#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'
]
},
)
.
##my_project/__main__.py
import sys
def main(args=None):
print("Do Something")
if __name__ == "__main__":
main()
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):

这个 Q 类似于 pkg_resources.DistributionNotFound when using a module installed from a bdist_rpm ,但不是构建 RPM。在那个 Q 中使用
--prefix
解决了这个问题。那对我没有用。我已经在 Windows 10、Linux Mint 和 Debian 上复制了同样的问题。此处存储库中的完整代码:https://github.com/maphew/scraps/tree/master/bug-dist-not-found
最佳答案
我刚刚遇到了同样的问题。问题是代码可以在一台计算机上运行,但不能在另一台计算机上运行。我也在使用我制造的轮子。无论如何,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
重新安装了 pip 和我的包,然后入口点就可以工作了。
