我使用virtualenv 多環(huán)境來安裝
requirements.tx 文件
cmake >=3.14.0
opencv-python >= 4.1.0.25
dlib >= 19.9.0
進入到虛擬環(huán)境中執(zhí)行
pip install -r requirements.txt
其中安裝 dlib時出錯
ERROR: Complete output from command /var/local/www/HelloWorld/.env/bin/python3.7 -u -c 'import setuptools, tokenize;__file__='"'"'/tmp/pip-install-1worr3fc/dlib/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-f0_rr9_y/install-record.txt --single-version-externally-managed --compile --install-headers /var/local/www/HelloWorld/.env/include/site/python3.7/dlib:

中間省略

紅了一大片呀
出錯信息也挺多的，google了半天享潜，
有說沒裝cmake 幸斥、boost的其實不是伦意，最后在一篇文章 cpp項目編譯時報錯: c++: internal compiler error: Killed 中找到答案厨诸，沒想到呀飒赃，居然是內(nèi)存不夠[汗]
執(zhí)行下面方法吧

增加了交換空間锭环，再執(zhí)行
pip install dlib
終于成功了聪全，不敢相信眼睛了，搞了半天了辅辩。
(.env) [root@VM_0_5_centos XXX]# pip install dlib
