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')

我认为可能因为scipy已经存在，所以我试图删除scipy，仍然收到错误：

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


PackageNotFoundError: Package not found: Conda could not find '

我现在能做什么？我正在使用Mac。

Answer 1

如果已经满足依赖关系，请尝试安装scikit-learn包忽略scipy包：
```
conda install --no-deps scikit-learn
```

Answer 2

所有这些技巧在我的ubuntu机器上都无效。

最终，需要指定numpy和scipy版本。您可以通过

获取版本

conda list > /tmp/conda_tmp1
pip install -U scikit-learn
conda list > /tmp/conda_tmp2
diff /tmp/conda_tmp1 /tmp/conda_tmp2

然后检查输出
