Question

我正在尝试在conda中为Linux安装Gym软件包。我已经创建了一个虚拟环境，并且正在使用以下命令来尝试安装：

(gym_env) [quantrill@baesvlfil003 ~]$ conda install --name gym_env -c hcc gym

但是出现以下问题：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

我发现很难解释此错误，因此不确定从哪里可以尝试解决它。

我还尝试在创建环境的同时安装软件包，但是存在相同的问题。

Python版本-3.6.9 conda版本-4.7.12

希望有人能帮助我！

Answer 1

该错误表示软件包具有相互冲突的依赖项要求。鉴于您已尝试将其安装到没有安装其他任何东西的全新环境中，因此软件包维护人员需要修复此问题，并且您无能为力。

或者，您可以尝试pip install gym安装该软件包。请查看他们的README on GitHub，以获取更多信息。如果您不知道，可以use Pip in a conda environment。

Answer 2

尽管hcc频道托管着gym程序包，但它具有pyglet的要求，在hcc或defaults上不可用。尝试也包括conda-forge频道：

conda create -n gym_env -c hcc -c conda-forge python=3.6 gym

请注意，在创建用于特定目的的环境时，通常建议在创建时包括密钥包。
