pycocotools“需要Microsoft Visual C++ 14.0或更高版本”，尽管已安装

Question

我想安装TensorFlow对象检测API，为此，我需要pycocotools包，它依赖于Visual Studio C++ Build Tools v14或更高版本。

我已经分别尝试安装了完整的Visual Studio 2022和Visual Studio build tools 2019。无论我做什么，这都是我的错误消息：

  ERROR: Failed building wheel for pycocotools

我在一台安装了Anaconda3 2021.11 (Python3.9.7 64位)的Windows11机器上。

我在Visual Studio installer中的安装细节看起来像this。

非常感谢您的帮助。

我相信你会错过MSBuild的。您可以从visual studio安装程序中添加它。

我安装的是Here，pycocotools安装得很好。
