pip install dlib 在 Anaconda 环境中不起作用
Posted
技术标签:
【中文标题】pip install dlib 在 Anaconda 环境中不起作用【英文标题】：pip install dlib not working in Anaconda environment 【发布时间】：2021-10-17 02:54:21 【问题描述】：我正在关注 tutorial，以使用以下 yml file 启动和运行 anaconda 环境。问题是，我始终只在这种环境中遇到错误。我已经尝试在 cmd 和 base (root) Anaconda 环境中运行 pip install dlib 并且他们成功了。我为 Visual Studio Community 2019 安装了 CMake 和 C++ 构建工具。我不确定还能尝试什么，我还验证了我的环境变量中有我的 CMake bin 路径。知道我在这里缺少什么吗？
我在环境中使用 Python 3.7.3

ERROR: Failed building wheel for dlib
【问题讨论】：
【参考方案1】：尝试通过在命令行中运行以下代码在 Anaconda 中创建一个新的虚拟环境
conda create --name opencv-env python=3.6
之后，激活环境
conda activate opencv-env
最后，运行以下命令安装 OpenCV 和其他重要包
pip install numpy scipy matplotlib scikit-learn (spyder/jupyter or whatever environment you are using)
pip install opencv-contrib-python
pip install dlib
如果之后您仍然收到要求您更新支持 C++11 的 Virtual Studio 的错误，请运行以下命令
pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f
