从.yml创建的Conda env提供“意外错误”

时间：2020-03-04 16:47:35

标签： python python-3.x anaconda conda environment

我刚刚重新安装了anaconda（python 3.7），并试图从以前制作的.yml加载环境。但是，我尝试的每个.yml都会产生未知错误... 

conda env create -f environment.yml

产生：

An unexpected error has occurred. Conda has prepared the above report.

在卸载conda之前，我知道环境可以正常运行！任何建议，将不胜感激！

经过更多调查后，问题出在文件的编码上！使用记事本中的“另存为”将编码更改为UTF-8即可解决此问题。
