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

Question

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

我都尝试单独安装完整的 Visual Studio 2022 以及 Visual Studio 构建工具 2019。不管我做什么，这都是我的错误信息：

  ERROR: Failed building wheel for pycocotools

我在安装了 Anaconda3 2021.11（Python 3.9.7 64 位）的 Windows 11 机器上。

我在 Visual Studio 安装程序中的安装详细信息如下所示 this.

非常感谢您的帮助。

Answer 1

我相信您缺少 MSBuild。您可以从 Visual Studio 安装程序中添加它。

Here 是我安装的，pycocotools 安装正常。
