即使直接在通道中列出包，Anaconda3 PackagesNotFoundError也是如此

Question

我正在尝试将ROOT包与root_numpy包一起安装到我的Python 3模块列表中。我正在运行Windows 10。

我试过了：

conda install root
conda install root-numpy

我也尝试过：

conda install root -c nlesc
conda install root-numpy -c nlesc

两者都失败并给我：

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

      - root
      - root-numpy

Current channels:

  - https://conda.anaconda.org/NLeSC/win-64

现在我知道频道https://anaconda.org/nlesc/已经列出了这两个软件包，无论出于何种原因我都无法在调用提示时找到它们。我的导航器也是最新的，所以在这方面应该没有问题。
