 * 特殊处理, 用于解决 @maxgraph/core 不能正常使用的问题, 会出现以下错误:
 * ERROR in ./node_modules/.pnpm/@maxgraph+core@0.12.0/node_modules/@maxgraph/core/dist/index.js 174:0-24
 * Module not found: Error: Can't resolve './types' in 'io.sc.platform.core.frontend/node_modules/.pnpm/@maxgraph+core@0.12.0/node_modules/@maxgraph/core/dist'
 * Did you mean 'types.js'?
 * BREAKING CHANGE: The request './types' failed to resolve only because it was resolved as fully specified
 * (probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
 * The extension in the request is mandatory for it to be fully specified.
 * Add the extension to the request.
 *
 * 解决方案: 删除 node_modules/@maxgraph/core/package.json 文件中 [ "type" : "module" ] 属性
