Question

我想与Dlib合作进行面部地标检测，并尝试将其安装在我的macOS Sierra上。我按照main GitHub Repo for dlib中的说明操作。

进入examples文件夹后，我首先执行了以下操作：

mkdir build; cd build; cmake .. ; cmake --build .

恢复到父目录，我执行了以下操作：

sudo python2.7 setup.py install

完成38％后，这遇到了20多个错误：

error: cmake build failed!

稍微调查一下，我感觉有一条小路径（到python）我需要改变以使一切工作。参考a similar problem，他改变了CMakeCache.txt中的一些路径，但我不确定哪条线/部分。此外，还有4个CMakeCache.txt文件。我应该改变哪一个（如果有的话）？

Ajays-MacBook-Pro:dlib Ajay$ find . -name "CMakeCache.txt"
./examples/build/CMakeCache.txt
./examples/build/cpp11_test_build/CMakeCache.txt
./tools/python/build/CMakeCache.txt
./tools/python/build/cpp11_test_build/CMakeCache.txt

还有其他解决办法吗？我该怎么办？任何帮助将不胜感激！

Answer 1

请参阅我的回答here

长话短说，你可以解决这个问题even with xQuartz installed。

Git中的最新版本似乎有效，但PyPi存储库尚未更新。

在此之前，请使用以下命令：

git clone https://github.com/davisking/dlib.git
cd dlib
pip install .

Answer 2

由于我的计算机上安装了多个python版本，我无法使用Dlib。 Macbook Pro（2014）预装了python2.7.10，应该不更新。如果需要更新版本，则需要将它们与v2.7一起安装。我用了anaconda并在我的电脑上安装了python3.5。然而，这似乎是问题中陈述的问题的根源。卸载Anaconda和python3.5后，Dlib开始工作时没有错误。原因尚不清楚，但仍然是一个令人满意的工作。
