Angular CLI 3rd 方库安装失败 [英] Angular CLI 3rd party lib installation failing

问题描述

嗯，我有一个奇怪的情况.我遵循了第 3 方库安装的所有指南.当我实际运行 ng serve 时，我可以看到 dis/vendor/redux 下的库.但是当我打开浏览器时，我的应用程序不起作用，并且当我在开发人员工具中检查资源时，该库不存在.我应该在哪里寻找问题?我的意思是怎么可能在 dist 文件夹中我可以看到库(在 webstorm 中)但在浏览器上却没有出现?

Well, i have a strange situation. I followed all the guides for 3rd party lib installation. When i run ng serve actually i can see the library under dis/vendor/redux. But when i open the browser my app doesnt work and when i check for the resources in developer tools, the library doesnt exist. Where should i look for the problem ? i mean how it is possible that in dist folder i can see the library(in webstorm) but on the browser it doesnt appear ?

推荐答案

我可以建议您一个解决方法，直到他们获得对 3rd 方库的更好支持.它对我有用:)

I can suggest you a workaround until they get better support for 3rd party libs. It worked for me :)

只要确保你在 src/index.html 中链接了你的 redux 路径

Just make sure you linked your redux path in your src/index.html

<script src="/vendor/redux/dist/redux.js" type="text/javascript"></script>

如果它不起作用，请确保您的 system-config.js 保持这样

If it doesnot work make sure your system-config.js remains like this

const packages: any = {
  'redux':{format: 'cjs',defaultExtension: 'js', main: 'redux.js'}
};

希望你让它运行:)
