是什么原因引起的？我安装了其他包没有问题。
答案 0 :(得分：7)
由于我无法发表评论，我将在此处回答。
我曾经遇到过这个问题。我通过执行以下操作来修复它：
pip install --upgrade pip
pip install --upgrade setuptools
有些讨论将此与Python 3 *以及其他版本为pip的问题联系起来。
如果升级pip和setuptools不适合您，请尝试使用Python 2.7 *。
我已经使用Python 2.7.13和pip v9.0.1在我的机器上进行了测试。
答案 1 :(得分：0)
好吧，如果您使用的是python 3.6，可以通过以下步骤解决此问题
1）pip install --upgrade pip setuptools
2）pip install-升级google-cloud-datastore
对我来说，它奏效了。
谢谢
