我正在尝试使用Ubuntu16.04在我的PC中安装python-pyqt5。

但是当我检查小麦时，我有PyQt5

>>from PyQt5.Qt import PYQT_VERSION_STR
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named PyQt5.Qt

系统说，我没有PyQt5的模块。

如何在我的Ubuntu16.04中安装PyQt5和QtCreator。

Answer 1

Ubuntu具有Python2和3。两种版本的模块都不同。

尝试安装pip和列表模块，以查看在任何一种安装中是否都存在。 如果您使用的是Python2：

sudo apt install python-pip
pip list

对于Python3：

sudo apt install python3-pip
pip3 list

如果您希望通过pip安装，则只需执行“ pip install PyQt”或“ pip3 install PyQt”。
