python - Python3.7 pip install requirements_string 解析错误

Question

我对python编码很陌生。我正在尝试在我的 python 脚本中使用现有的自定义包。

所以我想将一个 python 包与我的一个 python 脚本一起使用。要使用现有的包（或*.egg）文件，我遵循以下命令：

1. 通过执行以下命令，从我的 lib 的根目录构建一个 python egg 发行版：python3 setup.py bdist_egg
2. 在我的 python 脚本目录中尝试执行以下命令来安装.egg在上面的步骤中创建的：python3.7 -m pip install <path>/<to>/dist/<my_custom_lib>-0.14.0-py3.7.egg

这给了我以下错误：

ERROR: Exception:

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcb in position 12: invalid continuation byte

无法弄清楚为什么会发生这种情况。如果这是由于setup.py主库中的文件内容，这是它的内容：

from setuptools import setup, find_packages

setup(
    name='my_custom_lib',
    version='0.14.0',
    packages=find_packages(),
    url='https://www.my_custom_lib.com/qa/my_custom_lib',
    license='my_custom_lib Networks',
    author='my_custom_lib',
    author_email='my_custom_lib@my_custom_lib.com',
    description='Simulator library for the my_custom_lib Platform',
    long_description='''
        This Python module provides functionality to simulate an STB client
    using various protocol implementations, to test the
        my_custom_lib platform''',
    classifiers=[
        'Development Status :: 3 - Alpha',
        'Environment :: Console',
        'Intended Audience :: Telecom',
        'Programming Language :: Python',
    ],
    install_requires=[
        'protocols',
        'numpy',
        'requests',
        'pycrypto',
        'psutil'
    ],
)

不知道是什么导致了这个问题，或者我在这里做错了什么。感谢您对此的所有投入和评论。
