我正在尝试在EC2 ubuntu 16.04上安装dlib，我尝试了在Google上建议的许多选项，例如this，但是遇到了错误，我将其安装在本地计算机上，这很简单且易于安装。自从我一直在思考以来，我还尝试通过更改环境来解决此问题，这可能是某些python版本兼容性问题，但是python3也遇到了相同的错误。 在这里输出：

我找不到这里出什么问题了？由于同一命令在本地计算机上运行
答案 0 :(得分：3)
经过一些研发，我注意到c ++编译器至少需要4GB的内存，因此我只需将ec2 t2.micro升级到t2.medium，即可轻松安装。基本上是更少的RAM错误。
答案 1 :(得分：1)
您的C ++编译器崩溃了。将您的操作系统上的编译器版本与发生故障的系统进行比较。您的解决方案可能是过时的编译器/工具链。
答案 2 :(得分：0)
我的环境详情：
<块引用>python 3.7 & Ubuntu 16.04
1) 分配root权限，先更新ubuntu
sudo su
apt-get update
2) 检查 Python 和 pip 的版本和路径。
which python3
python3 -V
which pip3
pip3 -V
3)
pip3 install cmake
4)
apt-get install -y --fix-missing \
build-essential \
cmake \
gfortran \
git \
wget \
curl \
grapgicsmagick \
libgraphicsmagic-dev \
libatlas-dev \
