在Windows 10 Home（64位）上安装后无法使用Anaconda分发-缺少python36.dll

Question

我正在尝试通过笔记本电脑（Windows 10 Home，64位，Intel i5 6200U）上的Anaconda发行版安装Python。我从https://www.anaconda.com/download/（3.7版）下载了Anaconda3-5.3.0-Windows-x86_64.exe文件，并遵循操作方法文档中的所有说明进行操作，并遵循所有默认设置（http://docs.anaconda.com/anaconda/install/windows/） 。

例如，当我尝试打开Jupyter笔记本时，它显示内核错误。通过单击错误消息，我收到此消息：

更新：在@Surya Radhakrishnan建议之后，我在conda控制台中输入

conda install ipykernel

但是现在，我收到此错误消息：

我多次重新安装了Anaconda，并尝试了不同版本，但没有帮助。 Jupyther Notebook控制台显示以下内容：

通常，当我们尝试访问未安装ipykernel的jupyter笔记本时，会出现此错误。如果没有，请检查并安装ipykernel。

conda install ipykernel
