“没有找到分销，并且是由应用程序要求的。”当使用pyinstaller与setuptools

Question

我正在尝试从setuptools发行版中实现可执行文件，我有以下结构：

TEST-DIST
├── app.spec
├── my_package
│   ├── __init__.py
│   ├── __main__.py
│   ├── script1.py
│   └── script2.py
└── setup.py

setup.py：

from importlib.metadata import entry_points
import setuptools

setuptools.setup(
    name="testapp",
    version="0.0.1",
    author="Example Author",
    author_email="[email protected]",
    description="A small example package",
    url="https://github.com/pypa/sampleproject",
    project_urls={
        "Bug Tracker": "https://github.com/pypa/sampleproject/issues",
    },
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    entry_points={'console_scripts': ["mytestscript1=my_package.script1:main", "mytestscript2=my_package.script2:main"]},
    python_requires=">=3.6"
)

app.spec，使用此脚本要与setuptools一起使用，

block_cipher = None


def Entrypoint(dist, group, name, **kwargs):
    import pkg_resources

    # get toplevel packages of distribution from metadata
    def get_toplevel(dist):
        distribution = pkg_resources.get_distribution(dist)
        if distribution.has_metadata('top_level.txt'):
            return list(distribution.get_metadata('top_level.txt').split())
        else:
            return []

    kwargs.setdefault('hiddenimports', [])
    packages = []
    for distribution in kwargs['hiddenimports']:
        packages += get_toplevel(distribution)

    kwargs.setdefault('pathex', [])
    # get the entry point
    ep = pkg_resources.get_entry_info(dist, group, name)
    # insert path of the egg at the verify front of the search path
    kwargs['pathex'] = [ep.dist.location] + kwargs['pathex']
    # script name must not be a valid module name to avoid name clashes on import
    script_path = os.path.join(workpath, name + '-script.py')
    print("creating script for entry point", dist, group, name)
    with open(script_path, 'w') as fh:
        print("import", ep.module_name, file=fh)
        print("%s.%s()" % (ep.module_name, '.'.join(ep.attrs)), file=fh)
        for package in packages:
            print("import", package, file=fh)

    return Analysis(
        [script_path] + kwargs.get('scripts', []),
        **kwargs
    )

a = Entrypoint("testapp", 'console_scripts', 'mytestscript1')
pyz = PYZ(a.pure, a.zipped_data)

exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='mytestscript1')

我首先使用python3 -m构建，然后我执行Pyinstaller pyinstaller pyinstaller app.spec.spec.spec.spec.spec.spec。，导致以下错误：

27 INFO: PyInstaller: 4.10

    dist = get_provider(dist)

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'testapp' distribution was not found and is required by the application

调用异常是因为pkg_resources.get_entry_info在从Pyinstaller执行时找不到我的发行版，但是当我从任何正常脚本中运行它root可以找到没有问题的发现：

>>> import pkg_resources
>>> pkg_resources.get_entry_info("testapp", 'console_scripts', 'mytestscript1')
EntryPoint.parse('mytestscript1 = my_package.script1:main')

没有解决方案在这里

Answer 1

我认为我们可能遇到同样的问题。我具有与您相同的文件结构，包装名称的名称与代码所在的目录不同的内容（命名为testapp ），但目录命名为my_package）。我注意到，当我pip install我的软件包时，在site-packages egg> egg-info目录的名称（或> dist-info也许在您的情况下）是testapp_etc_.egg-info，源代码目录为my_package。我将其手动更改为mypackage_etc_.egg-info和pkg_resources能够找到入口点。

我还应该提到，我不需要对.spec文件进行任何更改。我昨天凝视着Setuptools的食谱，并放弃了，我只是在使用pyinstaller时就使用了常规的命令行参数。最后，手动更改目录的名称不是这里的正确解决方案，我只是为了查看这是否是问题。实际解决方案是在setup.setup.setup（）中更改软件包参数的名称。

这可能对任何人都没有帮助，但我的存储库使用的是我的主要 python 发行版中的 pyinstaller，直到我在我的 venv 中安装了 pyinstaller。然后我得到：

where pyinstaller
C:\dev\code\t3-revue\.venv\small\Scripts\pyinstaller.exe
C:\Users\xxx\AppData\Local\Programs\Python\Python311\Scripts\pyinstaller.exe

当它使用我的 venv 中的那个（我从中发出命令）时，它起作用了：

$ pwd
/c/dev/code/t3-revue
$ cls; pyinstaller config/installer/eyebrain.spec -y
-> no error

希望有帮助。
