WebpackError:TypeError:Object(..)不是函数gatsbyjs生成错误(botframewo

Question

我正在尝试将botframework webchat集成到gatsby.js网站，gatsby成功开发了构建，但当我使用命令gatsby build运行生产构建时，它会抛出以下错误。

以下是MinimizableWebChat.js的完整代码，它取自微软的BotFramework Webchat

return next(action);

[lang]
);
const [loaded, setLoaded] = useState(false);
const [minimized, setMinimized] = useState(true);
const [newMessage, setNewMessage] = useState(false);
const [token, setToken] = useState();
const handleFetchToken = useCallback(async () => {

我知道你已经跟进了建议的链接https://www.gatsbyjs.com/docs/debugging-html-builds/#fixing-第三方模块来修复CCD_ 1问题。

但这种方式可能会阻止webpack正确编译commonjs网络聊天包，最终导致问题。

我也知道build-html的阶段在dev期间没有被调用的配置，这就是为什么在yarn start // gatsby develop时不会看到错误的原因。

然而，该文档还提出了另一种修复方法，即使用loadable-component使用代码分割技术。就我个人而言，我认为这种方式最适合你的项目，因为聊天应该只在客户端呈现。

这里有一些你需要改变的地方：

• 删除gatsby-node中的配置：

// Remove this
actions.setWebpackConfig({ ... }}

• 将yarn add @loadable/component应用于回购：

// Install `yarn add @loadable/component` // or with npm i -D yarn add @loadable/component
// Make your chat component to be loadable:
// pages/index.js
- import MinimizableWebChat from '../components/webchat/MinimizableWebChat'
+ import loadable from '@loadable/component'
+ const MinimizableWebChat = loadable(() => import('./../components/webchat/MinimizableWebChat'))
