Python3和Setuptools：安装EGG文件后运行脚本出现问题（模块未找到错误）

Question

在使用Python3/setuptools为我的pkg构建了一个EGG文件之后，我在尝试运行脚本时遇到了一些问题。如果在setup.py中使用zip\u safe=False，我可以正常运行脚本。但我得到了一个modulenofounderror。我做错了什么？我不想使用zip\u safe=False选项

我的项目结构如下：

.
|-- python_pkgs
|   |-- __init__.py
|   |-- acap
|   |   |-- __init__.py
|   |   |-- acap.py
|   |   |-- cfg
|   |   |-- pch_acap.pl
|   |   |-- spf.py
|   |   `-- tvpv.py
|   |-- parsers
|   |   |-- STIL1999ModelBuilderSemantics.py
|   |   |-- STIL1999Parser.py
|   |   |-- __init__.py
|   |   |-- grammars
|   |   `-- test
|   `-- utils
|       |-- __init__.py
|       |-- misc.py
|       |-- nbq.py
|       |-- splitter.py
|       `-- util.py
|-- run_acap.py
`-- setup.py

run_acap.py的内容：

    #!/nfs/sc/disks/mpe_tvpv_032/sw_tools/anaconda3/bin/python3.7 -B
    import sys
    print(sys.path)

    from python_pkgs.acap.acap import main

    if __name__ == "__main__":
       main()

setup.py文件的内容：

from setuptools import setup, find_namespace_packages

setup(
    name='python_pkgs',
    version='0.1',
    packages=find_namespace_packages(include=['python_pkgs.*'],
                                     exclude=['python_pkgs.parsers',
                                              'python_pkgs.parsers.*']),
    scripts=['run_acap.py']
)

要安装，我说：python setup.py install--prefixa path

安装目录内容如下所示：

$ tree
.
|-- bin
|   `-- run_acap.py
`-- lib
    `-- python3.7
        `-- site-packages
            |-- easy-install.pth
            |-- python_pkgs-0.1-py3.7.egg
            `-- site.py

我注意到bin/run_acap.py的内容有些不同：

#!/nfs/sc/disks/mpe_tvpv_032/sw_tools/anaconda3/bin/python -B
# EASY-INSTALL-SCRIPT: 'python-pkgs==0.1','run_acap.py'
__requires__ = 'python-pkgs==0.1'
__import__('pkg_resources').run_script('python-pkgs==0.1', 'run_acap.py')

现在运行这个脚本，我说：

setenv PYTHONPATH <a path>/lib/python3.7/site-packages
<a path>/bin/run_acap.py --help



 $ /nfs/sc/disks/mpe_tvpv_032/pgupta6/releases/acap/ww49.2/bin/run_acap.py --help

    ModuleNotFoundError: No module named 'python_pkgs'

但是如果我打开一个python解释器，只需键入import python\u pkgs导入就可以了。我不确定我在setup.py文件（或其他地方）中做错了什么。如何修复此错误？谢谢
