如何在typescript中使用cytoscape.js

    我试图将cytoscape.js与typescript结合使用,但编译器有问题。 我使用了NPM安装-保存的Cytoscape

    我得到以下错误:

    错误ts1192:module'“c:/work/node ou modules/@types/cytoscape/index”'没有默认导出。2从“细胞角”进口细胞角;

    import cytoscape from 'cytoscape';
    
    var cy = (<any>window).cy = cytoscape(CytoscapeDefaults.defaults);
    

    有趣的是,intellisense显示了传递给cytoscape的参数。

    如果我尝试运行它,我会得到几乎相同的错误:

    cytoscape_1.默认值不是函数

    这是我的tsconfig.json

    我发现了这个 issue 在Github上,这可以解决您的问题:

    "compilerOptions": {
        "sourceMap": true,
        "module": "esnext",
        "moduleResolution": "node",
        "target": "es5",
        "jsx": "react",
        "allowSyntheticDefaultImports": true,    // that is probably the important one
        "esModuleInterop": true,                 // this also
        "typeRoots": [
          "./node_modules/@types/"
        ],
    }
