如何解决在ubuntu上安装opencv4nodejs有问题
我是 appium 图像处理的新手，首先我需要安装 opencv4nodejs。但是当我尝试安装它时会返回一个错误：
code 1
npm ERR! path /home/linuxbrew/.linuxbrew/lib/node_modules/opencv4nodejs
npm ERR! command Failed
npm ERR! command sh -c node ./install/install.js
npm ERR! info install using lib dir: /home/linuxbrew/.linuxbrew/lib/node_modules/opencv4nodejs/node_modules/opencv-build/opencv/build/lib
npm ERR! /home/linuxbrew/.linuxbrew/lib/node_modules/opencv4nodejs/install/install.js:37
npm ERR! throw new Error('library dir does not exist: ' + libDir)
npm ERR! ^

我没有opencv，所以我已经安装了
pip install opencv-python
并且opencv的版本是'4.5.2'。但我仍然看到这个错误。你能帮我解决吗？ 我的系统是Ubuntu18.0.4
