ancoda3+pyqt5+eric安装

其余的安装过程网上很清楚，注意的就是安装的版本，pip默认安装的是最新版，但由于一些包的内核是QT的，因此会产生版本冲突的错误
利用，pip check可以查看需要的版本

(base) C:\windows\system32>pip check
spyder 3.3.6 requires pyqt5, which is not installed.
pyqtwebengine 5.13.2 requires pyqt5, which is not installed.
astroid 2.3.1 requires typed-ast, which is not installed.
xlwings 0.15.10 has requirement pywin32>=224, but you have pywin32 223.
spyder 3.3.6 has requirement pyqtwebengine<5.13; python_version >= "3", but you have pyqtwebengine 5.13.2
然后按照提示安装相应的版本即可
(base) C:\windows\system32>pip install pyqt5==5.12.0
Collecting pyqt5==5.12.0
