python - 我在 conda 中安装 scikit-learn 时出错

Question

当我尝试在 conda 中安装 scikit-learn 时，我收到以下错误

$ conda install scikit-learn 
Fetching package metadata ...........
Solving package specifications: .

Package plan for installation in environment     
/Users/xlnwel/anaconda/envs/ai:

The following NEW packages will be INSTALLED:

    scikit-learn: 0.19.0-np113py36_0
    scipy:        0.19.1-np113py36_0

Proceed ([y]/n)? y

ERROR conda.core.link:_execute_actions(335): An error occurred while installing package 'defaults::scipy-0.19.1-np113py36_0'.
FileExistsError(17, 'File exists')
Attempting to roll back.



FileExistsError(17, 'File exists')

我想可能是因为scipy已经存在，所以尝试删除scipy，还是报错:

$ conda remove scipy
Fetching package metadata ...........
Solving package specifications: .


PackageNotFoundError: Package not found: Conda could not find '

我现在可以做什么？我正在使用 Mac。

• 如果已经满足依赖项，请尝试安装 scikit-learn 包，忽略 scipy 包:

  conda install --no-deps scikit-learn
