PluginError: Unable to resolve a valid config plugin for llama.rn.

[will-lamerton]

Hey,

I'm trying to get my repo running with Llama.rn on iOS and Android with Expo. However, I cannot get past this when trying to build using any combo of build (npm ios, pnpm ios, npx expo run:ios, pnpx expo run:ios - same with Android equivalent commands.

Error:

PluginError: Unable to resolve a valid config plugin for llama.rn.
• main export of llama.rn does not appear to be a config plugin: the following error was thrown when importing ../node_modules/.pnpm/llama.rn@0.8.0_react-native@0.81.5_@babel+core@7.28.4_@types+react@19.1.16_react@19.1.0__react@19.1.0/node_modules/llama.rn/app.plugin.js: require() of ES Module ../node_modules/.pnpm/llama.rn@0.8.0_react-native@0.81.5_@babel+core@7.28.4_@types+react@19.1.16_react@19.1.0__react@19.1.0/node_modules/llama.rn/lib/module/expo-plugin/withLlamaRN.js from ../node_modules/.pnpm/llama.rn@0.8.0_react-native@0.81.5_@babel+core@7.28.4_@types+react@19.1.16_react@19.1.0__react@19.1.0/node_modules/llama.rn/app.plugin.js not supported.

^ Replaced repo destination with ../

This is the plugins snippet of my app.json:

"plugins": [
      "expo-router",
      [
        "expo-splash-screen",
        {
          "image": "./assets/images/splash-icon.png",
          "imageWidth": 200,
          "resizeMode": "contain",
          "backgroundColor": "#ffffff",
          "dark": {
            "image": "./assets/images/splash-icon-dark.png",
            "backgroundColor": "#000000"
          }
        }
      ],
      "expo-font",
      [
        "llama.rn",
        {
          "enableEntitlements": true,
          "entitlementsProfile": "production",
          "forceCxx20": true,
          "enableOpenCL": true
        }
      ],
      "expo-web-browser"
    ],

Any guidance or thoughts on how to overcome this would be great. I'm using MacOS 26.

I see you're using 0.8.0 which contains the fix for a similar issue I was having #236. I'm having no issue using expo 53, react native 0.79.5, and my plugin definition looks the same. I always run a npx expo prebuild -p ios --clean before running after changing packages, I'm not really sure what else could be wrong.

I am using Expo 54 and same error

Today I resolved this. Turns out it was my version of Node. I was getting the error on Node v22.9.0. After upgrading to Node v22.15.1 all was resolved. Hope this helps.
