未安装Conda PackageNotInstalledError：软件包未安装在前缀

标签： python anaconda jupyter

我是Anaconda的新用户，我的Anaconda导航器每次都无法启动。我在网上尝试了其他答案，例如设置PATH和Anaconda Prompt上的“ conda update --all”。即使完成所有操作，也会发生以下错误：

(base) C:\Users\utkar>conda update conda

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Anaconda3
  package name: conda

由conda创建的错误报告附后：

答案 0 :(得分：0)

我想知道这是否不是this bug的体现。

如果是这样，以下内容应会有所帮助：

conda update -n base conda (if you have conda >=4.4)

或对于较旧版本的conda：

conda update -n root conda
