Example is not working

[jorgtz]

I have cloned this project, then cd into example, then npx expo start and got

expo-speech-recognition/example
Error: Cannot find module 'expo/config-plugins'

How to solve it?
Also what node version is recommended for this project?
Thanks!

[jamsch]

Hi @jorgtz, you'll need to run npm install in the root directory of the project if you haven't already. That should also build the module so that you can use it in the example app.

Also, since this contains a native module that isn't part of the Expo Go app, you'll need to run npm run android or npm run ios once to build and install the app on to your device, before using npm start

I encountered the same error. The error is still there after I ran npm install

[jamsch]

Hey @danny188 Just to confirm: have you ran npm install inside both expo-speech-recognition-main\ and expo-speech-recognition-main\example\? I'll get a Windows machine to test it out soon.

[danny188]

Hi @jamsch , I was able to build after running npm install inside expo-speech-recognition-main\ (previously only ran inside expo-speech-recognition-main\example\). I've now ran into some new errors when trying to test it on Android 9.

@danny188 The Cannot read property 'useRef' of null error usually has something to do with how the npm packages were installed. What npm/node versions are you running, and are you running npm install?

[danny188]

Hi @jamsch , npm version 10.7.0
I have run npm install inside both expo-speech-recognition-main and expo-speech-recognition-main\example.

There was a npm error when I ran npm install inside expo-speech-recognition-main:

[jamsch]

@danny188 Unfortunately it seems like expo-module-scripts doesn't support Windows so I'm not sure what can be done there. I think the best luck you'll have running the example app is to do the following:

• Remove example/metro.config.js
• Remove the following from example/tsconfig.json:

 "paths": {
      "expo-speech-recognition": ["../src/index"],
      "expo-speech-recognition/*": ["../src/*"]
    },

• Remove the "plugins" section from example/babel.config.js:

plugins: [
      [
        "module-resolver",
        {
          extensions: [".tsx", ".ts", ".js", ".json"],
          alias: {
            // For development, we want to alias the library to the source
            "expo-speech-recognition": path.join(
              __dirname,
              "..",
              "src",
              "index.ts",
            ),
          },
        },
      ],
    ],

• Add "expo-speech-recognition": "0.2.21", under the "dependencies" section in example/package.json
• Run npm install and then npm run android

[jamsch]

@danny188 Also, I've just tested the permissions on an Android 9 emulator and it seems okay. I did have a slight bug on the example app where the state wasn't reset if the user denied permissions but I've pushed a small fix for that right now.

              "..",
