原因：在 PyQt 5.6(+) 版本中, 新增 QtWebEngineWidgets 代替QtWebKitWidgets。
示例代码:
#coding: utf-8
import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtWebEngineWidgets import *
class MainWindow(QMainWindow):
???def __init__(self, *args, **kwargs):
???????super().__init__(*args, **kwargs)
???????self.setWindowTitle("client")
???????self.setWindowIcon(QIcon(‘icons/icon.png‘))
???????self.resize(900, 600)
???????self.show()
???????self.browser = QWebEngineView()
???????url = ‘https://www.baidu.com‘
???????self.browser.load(QUrl(url))
???????self.setCentralWidget(self.browser)
if __name__==‘__main__‘:
???app = QApplication(sys.argv)
???window = MainWindow()
???window.show()
???sys.exit(app.exec_())

解决 No module named PyQt5.QtWebKitWidgets
