具有Vue和vue-cli-plugin-electron-builder的电子应用程序无法与Tesseract.js一起使用

Question

我已经用vue-service-cli创建了一个项目。在尝试使用tesseract OCR之后，我无法在本地和远程加载lang.traineddata。我已经尝试了tesseract.js存储库中的示例（他们的工作）和其他许多方法，但是没有结果。当我尝试加载它们时，我看到标准错误：

    Error opening data file ./eng.traineddata
    Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
    Failed loading language 'eng'
    Tesseract couldn't load any languages!
    AdaptedTemplates != nullptr:Error:Assert failed:in file /src/src/classify/adaptmatch.cpp, line 196
    trap!

[我怀疑这是.asar存档格式的问题（来自vue-cli-plugin-electron-builder），位于/node_modules/electron/dist/resources/electron.asar中。我可以从./public加载文件，但是我已经读过语言文件必须位于进程目录中-我不知道这是不是真的。某些配置无法一起使用。

我的代码

    const data = await Tesseract.recognize(
    "https://tesseract.projectnaptha.com/img/eng_bw.png",
    "eng",
    
      logger: console.log,
      corePath: window.location.origin + "/tesseract/tesseract-core.wasm.js",
      workerPath: window.location.origin + "/tesseract/worker.min.js",
      langPath: window.location.origin + "/tesseract/tessdata"
      //or
      langPath: path.join(__dirname, "tessdata")

编辑：我注意到https://github.com/auth0-blog/electron-vue项目与Tesseract.js正常工作。该项目使用Vue，但没有vue-vli-service，这意味着它没有vue-cli-plugin-electron-builder来证实上述论点。我仍在寻找使用vue-cli的解决方案
