如何更新miniconda和Spyder 4.2.1

Question

当我打开Spyder时，我看到一条消息

Spyder 4.2.1 is available! Instead, run the following commands in a terminal 
conda update anaconda
conda install spyder=4.2.1"

我之前安装了miniconda，所以我打开了anaconda提示符，然后键入

conda update anaconda

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Users\yongn\miniconda3
  package name: anaconda

然后我切换到

conda update miniconda

我得到了同样的错误：

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Users\yongn\miniconda3
  package name: miniconda

对如何更新miniconda有什么建议吗？

$ conda更新conda

conda是包管理器。Anaconda是包含超过100个套餐的大恩奇拉达。
