node.js - 尝试在 Ubuntu 中安装 opencv4nodejs 时权限被拒绝

Question

我尝试使用以下命令在 Ubuntu-20.04 中安装 opencv4nodejs，我的 Node 版本是 v12.19.0

sudo npm i -g opencv4nodejs

但是得到那些错误

info install installing opencv version 3.4.6 into directory: /usr/lib/node_modules/opencv4nodejs/node_modules/opencv-build/opencv
ERR! Error: Command failed: mkdir -p opencv
mkdir: cannot create directory ‘opencv’: Permission denied

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Answer 1

1. 使用 sudo 运行 NPM 安装可能会导致权限问题。您可以尝试完全删除 node_modules 目录并重新运行 NPM install it without sudo。

2. 还要确保您有权写入正在安装的目录？

3. 如果还是不行，请按照以下步骤操作:

   sudo npm install -g opencv4nodejs --unsafe-perm=true --allow-root
