python - 为什么我不能从 pypi 安装 PyQt5？

Question

我想在pycharm中使用PyQt5。尝试从可用包安装包后，出现错误消息:“安装包失败:安装包 PyQt5 时出错。”
完整的日志在这里:

    raise DistributionNotFound('No distributions at all found for %s' % req)
DistributionNotFound: No distributions at all found for PyQt5

我该怎么办？

这就是我所做的:

• 安装 Python 3.3 并添加到 PATH
• 已安装 PyQt5-5.2-gpl-Py3.3-Qt5.2.0-x64.exe

而且我不知道如何在pycharm中使用PyQt。
你能提供更多信息吗？

Answer 1

据我所知，您不能从 PyPI 安装 PyQt4/PyQt5。您必须单独安装它。

如果您看到 this链接，您可以看到 PyPI 上没有列出 PyQt5(同样适用于 PyQt4)的包。因此，您需要从 here 单独下载安装程序并安装它。

就是这样

DistributionNotFound: No distributions at all found for PyQt5

指的是。

[更新]:您很可能还需要以相同的方式安装 sip，方法如下:https://askubuntu.com/a/666336/12214
