deMacBook-Pro:bndcs yuansanmei$ python3 -m pip install httprunner==v4.3.0
Requirement already satisfied: httprunner==v4.3.0 in /Users/y/Library/Python/3.10/lib/python/site-packages (4.3.0)
Requirement already satisfied: black<23.0.0,>=22.3.0 in /Users/y/Library/Python/3.10/lib/python/site-packages (from httprunner==v4.3.0) (22.6.0)
Requirement already satisfied: pyyaml<6.0.0,>=5.4.1 in /Users/y/Library/Python/3.10/lib/python/site-packages (from httprunner==v4.3.0) (5.4.1)

解决：python3 -m pip install httprunner==v4.3.0 --target=/Users/y/Library/Python/3.10/lib/python/site-packages

然后又遇到了第二个问题：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
jsonsearch 0.0.2 requires pytest<=3.10.1,>=2.8.0, but you have pytest 7.2.0 which is incompatible.
===意思好像是pytest版本太高了。。

从问题提示来看，就是pip 的依赖项解析器当前未考虑安装的所有包。此行为是以下依赖项冲突的根源。

二、解决办法

python3 -m pip install pytest==v3.10.1 --target=/Users/y/Library/Python/3.10/lib/python/site-packages

我就根据错误提示，分别重新安装了以上四个版本要求的包，不再截图，把代码附上：

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple " pyqt5<5.13"
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple " pyqtwebengine<5.13"
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pathlib
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple ruamel-yaml
然后就没有报错了。

又出现了报错：
