    importlib_metadata
    more_itertools
    packaging
    pluggy
    py

    2、下载地址

    https://pypi.org/project/pluggy/#files

     3、安装

    pip install xxxx(插件全名)

    4、查看是否安装成功

    在控制台输入Python

    接着输入 import pytest,如果不给报错,就证明安装成功

    5、报错

    Traceback (most recent call last):
      File "D:/java/idea/workSpaces/test/pythonWeb/webmoutrs/com_pytest/test_pytest01.py", line 1, in <module>
        import pytest

        from _pytest.assertion import register_assert_rewrite
      File "D:pythonpythonRootlibsite-packages\_pytestassertion\__init__.py", line 13, in <module>
        from _pytest.assertion import rewrite
      File "D:pythonpythonRootlibsite-packages\_pytestassertion
    ewrite.py", line 24, in <module>

      File "D:pythonpythonRootlibsite-packages\_pytest\_code\__init__.py", line 7, in <module>
        from .code import Code  # noqa
      File "D:pythonpythonRootlibsite-packages\_pytest\_codecode.py", line 15, in <module>
        import pluggy
      File "D:pythonpythonRootlibsite-packagespluggy\__init__.py", line 16, in <module>
        from .manager import PluginManager, PluginValidationError
      File "D:pythonpythonRootlibsite-packagespluggymanager.py", line 6, in <module>
        import importlib_metadata
      File "D:pythonpythonRootlibsite-packagesimportlib_metadata\__init__.py", line 471, in <module>
        __version__ = version(__name__)
      File "D:pythonpythonRootlibsite-packagesimportlib_metadata\__init__.py", line 438, in version
        return distribution(package).version
      File "D:pythonpythonRootlibsite-packagesimportlib_metadata\__init__.py", line 411, in distribution
        return Distribution.from_name(package)
      File "D:pythonpythonRootlibsite-packagesimportlib_metadata\__init__.py", line 179, in from_name
        dists = resolver(name)
      File "<frozen importlib._bootstrap_external>", line 1382, in find_distributions
      File "D:pythonpythonRootlibimportlibmetadata.py", line 400, in find_distributions
        found = cls._search_paths(context.pattern, context.path)
    AttributeError: 'str' object has no attribute 'pattern'
    
    Process finished with exit code 1

    由报错信息显示三个地方的site-packages出错:

    D:pythonpythonRootlibsite-packagesimportlib_metadata\__init__.py"
    "D:pythonpythonRootlibsite-packagespluggy\_init__.py",
    "D:pythonpythonRootlibsite-packages\_pytestassertion\__init__.py"

    解决方法:
    查看pytest所依赖的这三个包的版本,将其更新至需要版本
