ImportError：找不到lxml，请安装它

Question

我正在通过有关udemy的jupyter笔记本进行工作，此主题是关于熊猫的，关于以下问题之一，我会收到此错误消息：

ImportError                               Traceback (most recent call last)

    752     return _valid_parsers[flavor]

    753 

ImportError: lxml not found, please install it

（我正在使用python 3.7，我已经下载了anaconda）

然后，我尝试使用以下命令在命令提示符中安装lxml：

pip3 install lxml

我不确定如何解决此问题。
