为Anacond安装IsolationForest（ScikitLearn）

Question

我试图在我安装的Anaconda上运行IsolationForest，但它似乎不包含在Anaconda repo中。你知道吗

我已经安装了python3.6。我检查了IDE中的库以查看IsolationForest是否包含在ensembles中，而不是。我试过pip和conda update scikit-learn。另外，我尝试通过pip install git+git://github.com/scikit-learn/scikit-learn直接从git安装，但收到错误消息。你知道吗

这是运行pip install git+git://github.com/scikit-learn/scikit-learn时返回的内容：

我希望能够安装最新的完整版本的sklearn，这样我就可以充分利用这个库。你知道吗
