c++ - 安装 dlib 时出错

Question

我关注了this tutorial安装 dlib 但是当我运行 pip install dlib我明白了

Collecting dlib

error: cmake configuration failed!

有什么解决办法的建议吗？

更新

我使用的是 ubuntu 16.04

我还注意到，当我运行 sudo pip install dlib 时它有效但是 然后我得到

 (py3_dlib_tutorial) ~$ python

>>> import dlib
Traceback (most recent call last):

ModuleNotFoundError: No module named 'dlib'

更新

似乎是在此之前的修复导致了错误

我在我的 .bashrc 中禁用了这一行

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/leo/anaconda3/lib

这是制作 mkvirtualenv 所必需的工作。 现在pip install dlib工作了，但我仍然遇到类似的错误

Answer 1

要解决此错误:

python
Python 3.6.0 |Anaconda custom (64-bit)| (default, Dec 23 2016, 12:22:00)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux 
Type "help", "copyright", "credits" or "license" for more information.
>>> import dlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/leo/anaconda3/lib/python3.6/site-packages/dlib/__init__.py", line 1, in <module>
from .dlib import *
ImportError: /home/leo/anaconda3/bin/../lib/libstdc++.so.6: version     `GLIBCXX_3.4.21' not found (required by /usr/lib/x86_64-linux-
gnu/libboost_python-py35.so.1.58.0)

您需要从 Python 3.6 迁移到 Python 3.5。 如果您使用的是anaconda，可以通过设置新环境来完成:

conda create -env_name python=3.5 anaconda
activate env_name
conda install -c menpo dlib 

这应该可以工作，并且您的 dlib 可以正常工作。
