无法在 python 3 上安装 dlib

Question

我正在尝试在 python 3.7 上安装 dlib，但总是失败

我已经安装了 cmake 并将其添加到我的环境中，我已经将我的 pip 升级到最新版本，但每次我运行

pip install dlib

它returns错误为

我也安装了它通过:

到这里https://pypi.org/simple/dlib/
选择 dlib-19.18.0.tar.gz
解压，进入文件夹
打开命令行然后运行pythonsetup.py安装

它returns:

我很迷茫，任何回应或建议将不胜感激。谢谢

Answer 1

Python 3.6（64 位）必须已经安装。
运行 Windows 提示命令。您可以在搜索栏上输入“CMD”。 记得点鼠标右键然后“运行以管理员身份”，否则可能没有权限安装库
在提示符下输入命令

python -m pip 安装https://files.pythonhosted.org/packages/0e/ce/f8a3cff33ac03a8219768f0694c5d703c8e037e6aba2e865f9bae22ed63c/dlib-19.8.1-cp36-cp36m-win_amd64.whl#sha256=794994fa2c54e7776659fddb148363a5556468a6d5d46be8dad311722d54bfcf 4. 看到“Successfully installed dlib”的提示，表示安装完成

Answer 2

通过使用 C++ 安装 VS 解决。

Answer 3

你自己想出来了，但我想对你的安装方法做一些说明：

pip install dlib

因为 pypi 上只有 tar.gz，它会下载它，然后在安装 reuqirements

后尝试运行 setup.py

因此，您手动执行 tar.gz，提取它并运行ning python setup.py install 与第一个命令和

是一样的

python -m pip install  https://files.pythonhosted.org/packages/1e/62/aacb236d21fbd08148b1d517d58a9d80ea31bdcd386d26f21f8b23b1eb28/dlib-19.18.0.tar.gz

最后也是这样，正在尝试运行setup.py安装

在这种情况下，它涉及 c/c++ 代码的编译，这需要安装正确的 compiler/build 工具，而 pip 无法处理。它不是为此任务而构建的。

Answer 4

请设置您的编译器路径变量：

export CC=/usr/bin/gcc

然后再次执行 pip install dlib。它应该工作。您可能还想查看 usr/bin gcc 的正确路径。

无法在 python 3 上安装 dlib

unable to install dlib on python 3
