PyQT5 Anaconda 安装 - 未考虑包

PyQT5 Anaconda installation - packages not taken in to account

我尝试过多种方式在 Conda 中安装 pyqt5,最近是这样的:

pip3 install pyqt5==5.12.0

但是,在任何情况下,我都会收到一个我无法解决的错误,在安装较新版本的 pyqt5 时也是如此:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.1.5 requires pyqtwebengine<5.13; python_version >= "3", which is not installed.

我的包裹看起来像:

# packages in environment at C:\ProgramData\Anaconda3:
#
# Name                    Version                   Build  Channel
pyqt5                     5.12                     pypi_0    pypi
pyqt5-sip                 4.19.19                  pypi_0    pypi

知道我必须更改什么吗?

已解决:我有 Python 3.8,但 PyQt5 仅适用于 Python 3.4。安装 PyQt6 解决了问题。
