Step-by-Step Guide to Fix the Issue:

1. Create a new Rspeedy project:

   npm create rspeedy@latest
   

2. Navigate to the project directory:

   cd 'project_name'
   

3. Modify the package.json:

   • Search for "@lynx-js/react-rsbuild-plugin": "^0.9.0" and change it to:

     "@lynx-js/react-rsbuild-plugin": "npm:@lynx-js/react-rsbuild-plugin-canary@^0.9.0"
     

4. Run npm install:

   npm install
   

5. Double-check package-lock.json:

   • Open package-lock.json and verify that the version for @lynx-js/react-rsbuild-plugin is resolved to @lynx-js/react-rsbuild-plugin-canary. It should look like:

     "node_modules/@lynx-js/react-rsbuild-plugin": {
       "name": "@lynx-js/react-rsbuild-plugin-canary",
       "version": "0.9.0",
       "resolved": "https://registry.npmjs.org/@lynx-js/react-rsbuild-plugin-canary/-/react-rsbuild-plugin-canary-0.9.0.tgz"
     }
     

6. Fix the index.js file:

   • Open node_modules\@lynx-js\tasm\index.js, search for:

     let encode = encode_napi;
     

   • Change it to:

     let encode = getEncodeMode();
