我正在尝试运行项目：
https://github.com/ryanlayer/COvid19
我正在努力按原样执行它。
但当我执行命令创建新的conda环境并从environment.yml文件安装包列表时，我得到了以下错误：

我第一次在Windows中尝试这个操作，但得到了相同的错误，现在我使用Ubuntu，问题仍然存在，所以我不认为这是我使用的操作系统的问题。
如果要安装conda-forge包，请在yaml文件中指定它。
例如，我想安装"；poppler"；。这是一个conda-forge包(conda install -c conda-forge poppler(，所以我创建了一个yaml文件，如下所示：
name: myEnv
channels:
- defaults
dependencies:
- python==3.8
- pip
- conda-forge::poppler=22.04.0
- pip:
# works for regular pip packages
- opencv-python==4.6.0.66
如您所见，我添加了channels，还为proppler指定了conda-forge。
