python - CondaEnvException : Pip failed. 尝试使用 .yml

我正在尝试使用 .yml 文件在 conda 中创建一个环境。这是我运行的命令，

git clone https://github.com/fastai/fastai
cd fastai
conda env create -f environment.yml

最后一条命令给出了错误。一切正常，直到某一 pip ，然后突然间我明白了:

Pip subprocess error:

我已经尝试了以下操作，但仍然出现上述错误:

  • 卸载环境重试
  • 在所有环境中将 pip 更新为当前版本
  • 以管理员身份运行 Anaconda Powershell 提示符并重试

谁能帮忙解决这个问题。我不知道为什么会这样，也欢迎解释。

最佳答案

更新 conda 对我有用:

conda update -n base -c defaults conda
