首先更新包：

## 方法一：这个会默认安装最新的版本 ##

sudo apt update
    sudo apt install python3-opencv

## 方法二： ##

**可能会好点，至少知道错哪了…**

## 1. 配置必要的环境： ##

sudo apt install build-essential cmake git pkg-config libgtk-3-dev \
        libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
        libxvidcore-dev libx264-dev libjpeg-dev libpng-dev libtiff-dev \
        gfortran openexr libatlas-base-dev python3-dev python3-numpy \
        libtbb2 libtbb-dev libdc1394-22-dev

## 2. 克隆opencv和opencv contrib资源 ##

mkdir ~/opencv_build && cd ~/opencv_build
    git clone https://github.com/opencv/opencv.git
    git clone https://github.com/opencv/opencv_contrib.git

## \- 3、克隆完成之后创建安装文件目录 ##

cd ~/opencv_build/opencv
    mkdir build && cd build

## \- 4、开始构建编译环境： ##

cmake -D CMAKE_BUILD_TYPE=RELEASE \
        -D CMAKE_INSTALL_PREFIX=/usr/local \
        -D INSTALL_C_EXAMPLES=ON \
        -D INSTALL_PYTHON_EXAMPLES=ON \
        -D OPENCV_GENERATE_PKGCONFIG=ON \
        -D OPENCV_EXTRA_MODULES_PATH=~/opencv_build/opencv_contrib/modules \
        -D BUILD_EXAMPLES=ON ..

当编译结束时出出现下面的内容：

## \- 5、开始编译 ##

make -j8

如果编译成功，会出现如下界面：

1.  错误1：大概在71%左右出现：

1.  错误2：大概84%左右出现，找不到文件路径：

#include "/home/wgj/opencv_build/opencv/modules/features2d/test/test_detectors_regression.impl.hpp"
    #include "/home/wgj/opencv_build/opencv/modules/features2d/test/test_descriptors_regression.impl.hpp"

**名字这个地方写的是你自己登录账号的名字**

1.  错误3：大概87%左右，出现跟错误二类似的错误：

，将其修改为：，找到用记事本打开/home/wgj/opencv\_build/opencv\_contrib/modules/xfeatures2d/test/test\_features2d.cpp，找到\#include “features2d/test/test\_detectors\_regression.impl.hpp”  
，将其修改为：

#include "/home/名字/opencv_build/opencv/modules/features2d/test/test_detectors_invariance.impl.hpp" 
    #include "/home/名字/opencv_build/opencv/modules/features2d/test/test_descriptors_invariance.impl.hpp"

## \- 6、安装opencv ##

sudo make install

## \- 7、测试： ##

pkg-config --modversion opencv4

## \- 至此，安装结束！ ##
