推荐答案

通常，此错误"PackageNotInstalledError:软件包未安装前缀." 是因为您的自定义环境没有conda基础设施.相反，它仅在您的基础上.要更新基本环境，请执行以下操作:

Usually this error, "PackageNotInstalledError: Package is not installed in prefix." is because your custom environment doesn't have the conda infrastructure. Instead, it is in your base only. To update the base environment:

conda update --name base conda

要查看已安装的版本:

conda list --name base conda

列表的示例输出；

# packages in environment at /Users/me/miniconda2:
#
# Name                    Version                   Build  Channel
conda                     4.6.14                   py27_0  
conda-env                 2.6.0                h36134e3_0
