安装根目录时出错

Question

我是Python的新手。我安装了miniconda来获取包iminuit和minuit。为此，我创建了一个新环境来避免冲突。但是当我尝试使用以下命令安装minuit时

conda install minuit -c conda-forge

我收到以下错误消息：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Collecting package metadata (repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

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

 - minuit

Current channels:

 - https://conda.anaconda.org/conda-forge/osx-64
 - https://conda.anaconda.org/conda-forge/noarch
 - https://repo.anaconda.com/pkgs/main/osx-64
 - https://repo.anaconda.com/pkgs/main/noarch
 - https://repo.anaconda.com/pkgs/r/osx-64
 - https://repo.anaconda.com/pkgs/r/noarch

To search for alternate channels that may provide the conda package     you're
looking for, navigate to

 https://anaconda.org

and use the search bar at the top of the page.

我该如何解决这个问题呢？

Answer 1

正如消息所说，该包在当前通道中不可用。如果你在anaconda.org上查找，你会发现：

https://anaconda.org/mutirri/minuit上面写着：

要使用conda安装此软件包，请运行以下命令之一：

conda install -c mutirri minuit

conda install -c mutirri/label/all minuit

Answer 2

我不确定欧洲核子研究组织的根包的版本，但我猜他们不再支持Minuit包，而是Imminuit that is more lightweight and Jupyter friendly。

因此，根据here，您可以使用以下命令安装此软件包

conda install -c anaconda iminuit
