Question

我在package.json中添加了config，rollup.config.js如下：

const rollupConfig = require('@ionic/app-scripts/config/rollup.config');
enter code hereconst replace = require('rollup-plugin-replace');

const isProd = (process.env.IONIC_ENV === 'prod');

console.log('cur ENV: ', process.env.IONIC_ENV);
const EnvConfig = {
  prod: {
    API_URL: ''
  },
  dev: {
    API_URL: 'http://localhost:3000'
  },
  deviceDev: {
    API_URL: 'http://192.168.1.7:3000'
  }
}

const curConfig = EnvConfig[process.env.IONIC_ENV]

const rollupConfigReplaceEnviroment = replace({
  exclude: 'node_modules/**',
  delimiters: ['<@', '@>'],
  // use the /environments/environment.dev as the default import(!), no stub needed.
  // note we only replace the "last" part of the import statement so relative paths are maintained
  'API_URL': curConfig.API_URL,
});

rollupConfig.plugins = rollupConfig.plugins || [];
rollupConfig.plugins.splice(0, 0, rollupConfigReplaceEnviroment);

module.exports = rollupConfig;

但是当我运行ionic serve -b时，会出现一个警告： ```

[22:54:11]  rollup: commonjs-proxy:/Applications/My-Project/sharemap/node_modules/@angular/http/@angular/http.es5.js
            has issued a warning: 'default' is not exported by 'node_modules/@angular/http/@angular/http.es5.js'
[22:54:11]  rollup: commonjs-proxy:/Applications/My-Project/sharemap/node_modules/@angular/core/@angular/core.es5.js
            has issued a warning: 'default' is not exported by 'node_modules/@angular/core/@angular/core.es5.js'

然后我在浏览器中运行我的应用程序，它显示错误：

ERROR ReferenceError: System is not defined
    at loadAndCompile (main.js:82094)
    at NgModuleLoader.load (main.js:82071)
    at ModuleLoader.load (main.js:82147)

    at callLifecycleHooksChildrenFirst (main.js:13179)
    at checkAndUpdateView (main.js:14211)

我认为这些可能是rollup-plugin-commonjs@8.0.2的错误，然后我将这些lib升级到8.2.0，但问题仍然存在。

MY @ ionic / app-scripts版本为2.1.4

我的离子信息：

cli packages: (/Applications/My-Project/sharemap/node_modules)

    @ionic/cli-utils  : 1.9.2
    ionic (Ionic CLI) : 3.9.2

global packages:

Answer 1

您必须使用下面给出的特定路径添加package.json;

"config": {
        "ionic_copy": "./config/rollup.config.js"
    },

和rollup.config.js文件将位于根目录下的config目录中，类似projectName/config/rollup.config.js

Ionic2在配置rollup.config.js后显示“系统未定义”
