Cannot read properties of undefined (reading 'TessBaseAPI')

const worker = await createWorker();
const rectangle = { left: 0, top: 0, width: 500, height: 250 };

(async () => {
await worker.loadLanguage('eng');
await worker.initialize('eng');
const {
data: { text }
} = await worker.recognize(
'https://tesseract.projectnaptha.com/img/eng_bw.png',
{ rectangle }
);
console.log(text);
await worker.terminate();
})();

I write this and return this

Please specify the version of Tesseract.js you are using in any bug reports, along with any other information that would be necessary to reproduce the behavior described.

I was unable to replicate this issue. I saved the following code into a file in the Node examples folder, and then ran the file out of that folder, and it ran as expected.

const { createWorker } = require('../../');

(async () => {
const worker = await createWorker();
const rectangle = { left: 0, top: 0, width: 500, height: 250 };
await worker.loadLanguage('eng');
await worker.initialize('eng');
const {
data: { text }
} = await worker.recognize(
'https://tesseract.projectnaptha.com/img/eng_bw.png',
{ rectangle }
);
console.log(text);
await worker.terminate();
})();

The same is happening with me.

Node.js v18.15.0

Code:

const { createWorker } = require("tesseract.js");

(async () => {
  const worker = await createWorker();
  await worker.loadLanguage("eng");
  await worker.initialize("eng");
  const {
    data: { text },
  } = await worker.recognize("https://tesseract.projectnaptha.com/img/eng_bw.png");
  console.log(text);
  await worker.terminate();
})();

Error message:

        throw Error(data);
        ^

package.json

{
  "dependencies": {
    "tesseract.js": "^2.1.0"
  }
}

@jonas-duarte Version 2.1.0 is an old/unsupported version that does not run on Node.js 18. The latest version at the time of this writing is v4.0.6. Please upgrade to the latest version of Tesseract.js (although anything v3 or higher should work).

I am closing this issue as I do not see any indication that this happens with supported versions of Tesseract.js.

[jonas-duarte]

It worked, thank you.

When I googled it, I was redirected to the v2.
