解决方法1（亲测有效）：
conda install -c conda-forge pycocotools
用conda装一下就好了，并且速度也快！
解决方法2（未亲测）：
conda install pycocotools -c Esri
解决方案三：
直接把这个包下载下来放到你anaconda虚拟环境所在的目录下中的site-packages文件夹内
pycococtools的安装包
pycocotools
提取码：i5d7
下载解压后得到两个文件，将以上两个文件夹复制至你anaconda虚拟环境所在的目录下中的site-packages文件夹内 [1]
如博主的目录为：
D:\Anaconda\ana\Lib\site-packages
