javascript - VSt上带有Node.js的“Error: Failed to detect OS”

Question

我正在使用tesseract.js进行OCR，但是当我更改exampleImage时，出现此错误。我根本找不到有关此错误的任何信息。先感谢您。

app.js

const exampleImage = 'https://d1q6f0aelx0por.cloudfront.net/product-logos/5431a80b-9ab9-486c-906a-e3d4b5ccaa96-hello-world.png';
const Tesseract=require('tesseract.js');
const worker = Tesseract.createWorker({
  logger: m => console.log(m)
});
Tesseract.setLogging(true);
work();

async function work() {
  await worker.load();
  await worker.loadLanguage('eng');
  await worker.initialize('eng');

  let result = await worker.detect(exampleImage);
  console.log(result.data);

  result = await worker.recognize(exampleImage);
  console.log(result.data);

  await worker.terminate();
}

Console.log

您的用法及其文档使用案例不匹配您是否检查了其文档？

https://github.com/naptha/tesseract.js/blob/master/docs/examples.md

例如，尝试像他们一样写作；

const { createWorker } = require('tesseract.js');
const exampleImage = 'https://d1q6f0aelx0por.cloudfront.net/product-logos/5431a80b-9ab9-486c-906a-e3d4b5ccaa96-hello-world.png';

const worker = createWorker({
  logger: m => console.log(m), // Add logger here
});

(async () => {
  await worker.load();
  await worker.loadLanguage('eng');
  await worker.initialize('eng');
  const { data: { text } } = await worker.recognize(exampleImage);
  console.log(text);
  await worker.terminate();
})();
