python - 使用从 bdist_rpm 安装的模块时 pkg_resources.DistributionNotFound

Question

我正在尝试创建我构建的 CLI 工具的 rpm。 rpm 正在创建并安装，没有错误。但是，当我尝试使用 CLI 时，出现以下异常:

    Traceback (most recent call last):
          File "/usr/local/bin/my_project", line 5, in <module>
            from pkg_resources import load_entry_point
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 3141, in <module>
            @_call_aside
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 3127, in _call_aside
            f(*args, **kwargs)
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 3154, in _initialize_master_working_set
            working_set = WorkingSet._build_master()
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 640, in _build_master
            ws.require(__requires__)
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 941, in require
            needed = self.resolve(parse_requirements(requirements))
          File "/usr/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg/pkg_resources/__init__.py", line 828, in resolve
            raise DistributionNotFound(req, requirers)
        pkg_resources.DistributionNotFound: The 'my-project==0.1.0' distribution was not found and is required by the application

我尝试使用以下文件创建一个简单的应用程序以使其正常工作，但我仍然遇到相同的异常

project/setup.py

import sys

def main(args=None):
     print("Do Something")

if __name__ == "__main__":
    main()

然后project/my_project/__main__.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'
        ]
     },
)

我正在使用命令 python setup.py bdist_rpm

创建 rpm

编辑

原因是 my_project 被安装到 usr/local/lib 而不是/usr/lib。如何更改默认路径？

Answer 1

我最终只是使用 --install-script 标志指定了一个自定义安装脚本，该标志使用 setup.py install 的前缀选项

安装脚本的内容: python setup.py install --single-version-externally-managed -O1 --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES --prefix /usr
