Angular 4 AOT 构建不适用于 Lodash 库
Angular 4 AOT build not working with Lodash Library
Angular 4 AOT 构建不适用于 Lodash 库。
我设法让 lodash 在 JIT 中构建和服务。
但是我在构建 AOT 时遇到了问题。
当我没有 lodash 时,AOT 工作正常,但我想让它与 lodash 一起工作。
这是我使用的命令:
"build:aot": "ngc -p tsconfig-aot.json && rollup -c rollup-config.js",
错误 git bash:
warning.indexOf 不是函数
尝试解决汇总错误:
我将 rollup-config.js 文件更新为:
if ( warning.message.indexOf("The 'this' keyword is equivalent to 'undefined'") > -1 ) { return;
来自:
if ( warning.indexOf("The 'this' keyword is equivalent to 'undefined'") > -1 ) { return;
结果:
这似乎 运行 汇总很好,但是当我执行“npm 运行 serve:aot”时,我得到了以下信息build.js 文件的控制台错误:
错误:未捕获(承诺):TypeError:void 0 不是函数。
这可能与添加的 lodash 库有关?
这是我的 tsconfig:
{
"compilerOptions": {
"target": "es5",
"module": "es2015",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,

},
"files": [
"src/app/app.module.ts",
"src/main.ts"
],
"angularCompilerOptions": {
"genDir": "aot",
"skipMetadataEmit" : true
}
}
这是我的systemjs.config:
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
'app': 'app',
// angular bundles

packages: {
app: {

}
}
},
rxjs: {
defaultExtension: 'js'
},
lodash: {
defaultExtension: 'js'
}
}
});
})(this);
这是我的汇总配置:
import rollup from 'rollup'
import nodeResolve from 'rollup-plugin-node-resolve'
import commonjs from 'rollup-plugin-commonjs';
import uglify from 'rollup-plugin-uglify'
//paths are relative to the execution path
export default {

onwarn: function(warning) {
// Skip certain warnings
// should intercept ... but doesn't in some rollup versions
if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }
// intercepts in some rollup versions
if ( warning.indexOf("The 'this' keyword is equivalent to 'undefined'") > -1 ) { return; }
// console.warn everything else
console.warn( warning.message );
},
plugins: [
nodeResolve({jsnext: true, module: true}),
commonjs({
include: ['node_modules/rxjs/**']
}),
uglify()
]
}

注:
我提到我在地图中为 systemjs.config 文件使用了 lodash。并在此文件的包部分。
我正在为此构建使用 angular.io 快速启动种子应用程序:https://angular.io/docs/ts/latest/guide/setup.html
运行ning npm 运行 build:aot 的 git 错误屏幕截图,lodash 设置为“'lodash':'npm:lodash/lodash/core.js" in systemjs.config.js 文件:
在你的 systemjs 中修改这一行
'lodash': 'npm:lodash/lodash/core.js'
或者你可以使用 lodash cdn,这让工作变得更容易
不久前我在导入的一些库中遇到了类似的问题,所以在绝望的尝试中我删除了 onWarn 函数:
onwarn:函数(警告){
// Skip certain warnings
// should intercept ... but doesn't in some rollup versions
if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }
// intercepts in some rollup versions
if ( warning.indexOf("The 'this' keyword is equivalent to 'undefined'") > -1 ) { return; }
// console.warn everything else
console.warn( warning.message );
},
从 rollup-config 文件和应用程序 AOT 编译,没有错误,目前在生产中工作正常,现在我知道出于各种原因这不是推荐的方法,但没有伤害也没有犯规我想如果这有帮助请告诉我。如果您仍然卡住,我总是可以在本地实现一些东西并尝试一下。
