从 github 存储库安装 wheel 文件时出现错误 pip（下载 pycocotools）

Question

我正在安装 Tensorflow (1.15.0) 以执行一些深度学习对象检测，但在 pip 安装 pycocotools 时遇到问题。我正在关注 this 教程，这是一个最初来自 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 this github 存储库下载一个 wheel 文件，在子目录 PythonAPI 下。我运行这样做的代码：

pip install git+https://github.com/philferriere/cocoapi#egg=pycocotools^subdirectory==PythonAPI

产生以下错误：

Collecting pycocotoolssubdirectory==PythonAPI

我怎样才能成功安装这个存储库？我需要 wheel 文件，以便我可以继续安装 pycocotools。注意：我已经安装了最新版本的 pip，所以这不是问题所在。
