python setup.py sdist bdist_wheel raises `TypeError: expected string or bytes-like object`

Question

问题陈述

将 packages= 设置为 [find_packages()] 时，我遇到了 TypeError。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。我想知道是否有人了解这里发生的事情。

供参考我运行 python 3.9.

setup.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,
  )

错误

TypeError: expected string or bytes-like object

设置断点

当我设置断点时，我发现结果是一个只有一个字符串的列表。

(Pdb) find_packages()
['spark_jobs']

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

Answer 1

find_packages() 已经 returns 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(),

在packages=['spark-jobs']中，包名的拼写必须与目录完全相同（并且目录名必须遵循Python命名规则），因此将其修复为

packages=['spark_jobs']
