推荐答案

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 安装它而无需 sudo.

1. Running NPM install with sudo might be causing a permissions problem. You could try completely removing the node_modules directory and re-running NPM install it without sudo.

还要确保您有权写入要安装的目录吗?

Also make sure you have permission to write to the directory you're installing in?

如果还是不行，请按以下步骤操作:

If it still doesn't work please follow this:

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