    你看报错问题,一行一行往下看,你就会发现有一处报错特别显眼

    File "/Users/***/Library/Python/3.8/lib/python/site-packages/pip/vendor/pep517/in_process/in_process.py", line 156, in prepare_metadata_for_build_wheel
    hook = backend.prepare_metadata_for_build_wheel
    AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel'

    他说你pip 有问题,当然知道这个估计你还一脸懵,你可以将这个报错

    AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel'

    Google 一下
    你就会立马得到解决方法啦。

    另外建议 虚拟环境or aconda管理包

      你在google之后,认为问题是什么?你具体尝试过什么方案?效果是什么?建议在问题描述中说清楚。

      我刚开始查到是pip升级问题,不是嘛emmmmm
      好嘞,然后问问题的标准模式,应该如上所述哦,描述自己做过什么努力,判断大概哪里的问题。云云。GitHub上搜索“how to ask questions”,就很棒。

      请先考虑用 PySide,后者是 Qt 官方支持的 Python 绑定。PyQt 是社区用户维护的版本

      --- google出来的解决方案都尝试过,但并不能解决问题 :)

      确实如楼上说的,“都尝试过” 这个描述其实不太现实,毕竟每个关键字都可以搜到无限量的链接。

      有时候可能是关键字选取的问题,可以描述一下用过什么关键字,具体搜到了哪个结果(可以贴链接),然后可以说一起研究怎么样优化关键字,乃至于更好的搜索技巧等等。

      更多的信息只在自己身上,每个人的状态都不一样,提供更多的上下文,才有利于大家一起捋清楚问题出在了哪。
