Question

conda 更新 conda >> 成功

conda update anaconda >> 给我一个错误，说 package is not installed in prefix。

Answer 1

通常此错误 "PackageNotInstalledError: Package is not installed in prefix." 是因为您的自定义环境没有 conda 基础结构。相反，它仅在您的基地中。要更新基础环境：

 conda update --name base conda

要查看您安装的版本：

 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
