python - python setup.py sdist bdist_wheel 引发`TypeError：预期的字符串或类似字节的对象`

问题描述

问题陈述

当设置packages=为[find_packages()]我遇到 TypeError 时。将 packages 变量直接设置为结果字符串 ( "spark_jobs") 时，我不再遇到意外异常。我想知道是否有人明白这里发生了什么。

供参考，我在 python 3.9 上运行。

安装程序.py

  setup(
      name=f"{PROJECT_NAME}",
      version=f"{VERSION}",
      description="f{PROJECT_DESCRIPTION}",
      long_description=README,
      long_description_content_type="text/markdown",
      url=f"{url}",
      author=f"{author}",
      classifiers=[
          "Programming Language :: Python :: 3",
          "Programming Language :: Python :: 3.7",
          "Programming Language :: Python :: 3.8",
          "Programming Language :: Python :: 3.9",
      ],
      packages=[find_packages()],
      include_package_data=True,
      install_requires=INSTALL_REQUIRES,
      tests_require=TESTS_REQUIRE,
  )

设置断点

当我设置断点时，我发现结果是一个带有单个字符串的列表。

(Pdb) find_packages()
['spark_jobs']

令人困惑的是，如果我packages=['spark-jobs']直接设置，我将不再遇到上述错误，但我也会得到一个空的

解决方案

find_packages()已经返回一个列表，您不需要将其包装在另一个列表中。正确的语法只是

  packages=find_packages(),

包名中packages=['spark-jobs']的名称必须与目录的拼写完全一样（并且目录名必须遵循 Python 命名规则）所以将其修复为

packages=['spark_jobs']
