无法将@ tensorflow / tfjs-node导入我的程序。我试图按如下方式导入它：
const tf = require('@tensorflow/tfjs-node')
并收到如下错误：
internal/modules/cjs/loader.js:638
throw err;
^
Error: Cannot find module '/home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node/lib/napi-v4/tfjs_binding.node'

但是当我尝试导入@ tensorflow / tfjs作为
const tf = require('@tensorflow/tfjs')
没有遇到错误。
我使用npm安装了@ tensorflow / tfjs-node
sudo npm install @tensorflow/tfjs-node
然后得到一个输出（如下）：
@tensorflow/[email protected] install /home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node
node scripts/install.js

这里有两个问题。
以root身份安装软件包
您想以root身份安装依赖项，但默认情况下npm不会以root身份运行。传递以下参数以启用root特权：
sudo npm install @tensorflow/tfjs-node --unsafe-perm=true --allow-root
您还应该重新考虑使用另一个（不是root）来运行脚本。
Tensorflow.js需要
require oftensorflow/tfjs-node不能按您的方式工作，该软件包@tensorflow/tfjs-node不会导出任何内容，仅需要使用本机C ++绑定。
这是应该如何做（来自本教程的引文）：
const tf = require('@tensorflow/tfjs');
require('@tensorflow/tfjs-node');
