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

Question

我正在尝试通过 Anaconda 发行版在我的笔记本电脑（Windows 10 Home，64 位，Intel i5 6200U）上安装 Python。我从https://www.anaconda.com/download/（3.7 版）下载了 Anaconda3-5.3.0-Windows-x86_64.exe 文件，按照操作指南文档中的所有说明进行操作，并坚持所有默认设置 (http://docs.anaconda.com/anaconda/install/windows/)。

当我尝试打开 Jupyter Notebook 时，它显示内核错误。通过单击错误消息，我收到以下信息：

更新：在@Surya Radhakrishnan 的建议下，我在conda 控制台中输入了

conda install ipykernel

但现在，我收到以下错误消息：

我多次重新安装 Anaconda 并尝试了不同版本，但没有任何帮助。 Jupyther Notebook 控制台显示：

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

conda install ipykernel
