jupyter-notebook - 开发 Jupyter Notebook 扩展时如何引入第三方 js 包

Question

我想为mermaid编写 Jupyter Notebook 扩展的扩展。或者更常见的是，如何将 npm 包 webpack 到 Jupyter Notebook Extension。

但是当我将mermaid包包含在 main.js 中时，遇到以下错误：

utils.js:62 Failed to load extension: ["nbextensions/notebook_mermaid/mermaid"] TypeError: _.constant is not a function
    at Object../node_modules/graphlibrary/lib/alg/dijkstra.js (mermaid.js:26950)
    at __webpack_require__ (mermaid.js:30)

我已经把代码上传到github了， https://github.com/Honghe/notebook_mermaid
