【问题描述】:
所以我正在尝试安装 PyQt 包,所以我只是在我的 Anaconda Prompt 上执行此操作:
C:\Users\USER>pip install PyQt5
Collecting PyQt5
Using cached PyQt5-5.15.0-5.15.0-cp35.cp36.cp37.cp38-none-win_amd64.whl (64.5 MB)
Collecting PyQt5-sip<13,>=12.8
Using cached PyQt5_sip-12.8.0-cp37-cp37m-win_amd64.whl (62 kB)
ERROR: spyder 4.1.4 requires pyqtwebengine<5.13; python_version >= "3", which is not installed.
ERROR: spyder 4.1.4 has requirement pyqt5<5.13; python_version >= "3", but you'll have pyqt5 5.15.0 which is incompatible.
所以我尝试了一个不同的版本:
pip install --upgrade --user pyqt5==5.12
然后事情发生了:
Collecting pyqt5==5.12
