我正在安装 Tensorflow (1.15.0) 以执行一些深度学习对象检测，但在安装 pycocotools 时遇到问题。我正在关注本教程，这是最初来自 YouTube 频道 Sentdex 的更新教程。为此，我也在使用 Anaconda Prompt。
创建并激活 conda 环境并安装所有需要的包（TensorFlow、lxml 等）后，我尝试运行命令pip install pycocotools包，但出现以下错误：

显然，需要从这个github 存储库中下载一个 wheel 文件，位于 PythonAPI 子目录下。我运行了这段代码：
pip install git+https://github.com/philferriere/cocoapi#egg=pycocotools^subdirectory==PythonAPI
产生以下错误：

如何成功安装此存储库？我需要 wheel 文件，以便继续安装 pycocotools。注意：我已经安装了最新版本的pip，所以这不是问题。
