You didn't mention an OS, but here is my experience with OSX - hopefully it is helpful to someone.您没有提到操作系统，但这是我使用 OSX 的经验 - 希望对某人有所帮助。
pyqt5 installed though pip appears to require python3 - and I couldn't find a way around it.尽管 pip 似乎需要 python3，但安装了 pyqt5 - 我找不到解决方法。 After spending a bit of time trying to figure this out recently, there are two options I know of:最近花了一些时间试图弄清楚这一点后，我知道有两种选择：
1) build from source, eg https://robonobodojo.wordpress.com/2017/02/08/installing-pyqt4-on-mac-osx/ , https://fredrikaverpil.github.io/2015/11/25/compiling-pyqt5-for-python-2-7-on-os-x/ , for pyqt4 (just in case), pyqt5, respectively. 1）从源代码编译，例如https://robonobodojo.wordpress.com/2017/02/08/installing-pyqt4-on-mac-osx/ ， https://fredrikaverpil.github.io/2015/11/25/编译-pyqt5-for-python-2-7-on-os-x/ ，分别用于pyqt4（以防万一），pyqt5。
2) install using conda https://docs.conda.io/en/latest/miniconda.html 2) 使用 conda https://docs.conda.io/en/latest/miniconda.html安装
I was unable to get 1) working for me (on OSX 10.14.5) due to, I believe, an issue with paths configuration.我无法获得 1) 为我工作（在 OSX 10.14.5 上），因为我相信路径配置存在问题。 But conda worked immediately.但是 conda 立即起作用了。 Once installed (by choosing the python2 install), just do conda install pyqt .安装后（通过选择 python2 安装），只需执行conda install pyqt 。
edit: there is also an Ubuntu guide for building from source here : https://plashless.wordpress.com/2014/03/26/building-pyqt5-for-python2-7-on-a-clean-ubuntu-13-10-build-machine/编辑：这里还有一个从源代码构建的 Ubuntu 指南： https : //plashless.wordpress.com/2014/03/26/building-pyqt5-for-python2-7-on-a-clean-ubuntu-13- 10-build-machine/
