PackagesNotFoundError: The following packages are not available from current channels:

我使用python 3.6和Windows 10

Answer 1

打开Conda提示，使用conda install mca代替pip install mca 它工作正常。它会安装在您的Conda虚拟环境本身中。这是Conda提示：

Answer 2

因此，我通过运行以下命令解决了该问题：

conda config --set channel_priority false.

然后使用命令run进行mca下载：

conda install mca

Answer 3

根据此（What do the operating system tags mean in the anaconda packages?），操作系统标签会显示该软件包可以安装到的系统。

当您提到使用Windows 10计算机时，要安装的软件包mca仅具有ljnux-64标记。所以我想你无法安装

在Anaconda上安装Python软件包mca
