Shoutem+React Native Webpack4项目tinycolor2的define未定义错误求助

Hey there, let's work through this issue together! The error you're seeing stems from tinycolor2's AMD-style export code that ESLint doesn't recognize as a valid global, and your Webpack setup might be handling the module format in a way that triggers this conflict. Here are actionable solutions to try:

1. Tell ESLint to recognize define as a global variable #

Since ESLint is flagging define as an undefined variable, you can explicitly mark it as a global in your ESLint config to suppress the error:

• Open your ESLint config file (usually .eslintrc.js or .eslintrc.json)
• Add the globals section to let ESLint know define is a valid global:

module.exports = {
  // ... your existing ESLint rules and settings
  globals: {
    define: 'readonly' // Marks `define` as a read-only global variable
  }
};

This is the quickest fix if the issue is just ESLint being strict about unrecognized globals.

2. Configure Webpack to handle tinycolor2's AMD code #

The tinycolor2 library includes AMD (Asynchronous Module Definition) code at the end, which might be conflicting with your Webpack setup. You can use imports-loader to override the define variable when processing tinycolor2:
First, install the loader if you haven't already:

npm install imports-loader --save-dev
# or
yarn add imports-loader --dev

Then add a rule to your webpack.config.js to target tinycolor2:

module.exports = {
  // ... other Webpack config
  module: {
    rules: [
      {
        test: require.resolve('tinycolor2'),
        use: 'imports-loader?define=>false'
      }
    ]
  }
};

This tells Webpack to replace any reference to define with false when loading tinycolor2, so the AMD export code won't execute (since it checks if define exists first).

3. Use the ES module version of tinycolor2 #

Newer versions of tinycolor2 provide an ES module build that avoids AMD/CommonJS wrapper code entirely. Try importing the ES module directly instead of the default entry:

import tinycolor from 'tinycolor2/dist/tinycolor.esm.js';

This skips the problematic AMD code, which should eliminate the define error.

4. Force a consistent tinycolor2 version in your dependency tree #

Since the error comes from a nested dependency (via Shoutem's boilerplate), you might be using an older version of tinycolor2 with problematic AMD code. You can force your project to use a newer, more compatible version using package manager overrides:

For npm: #

Add an overrides section to your package.json:

{
  "overrides": {
    "tinycolor2": "^1.6.0" // Use the latest stable version here
  }
}

For Yarn: #

Add a resolutions section to your package.json:

{
  "resolutions": {
    "tinycolor2": "^1.6.0"
  }
}

After adding this, reinstall your dependencies to apply the override.
