中文版示例：
1. 打开 [code-generator](https://github.com/alibaba/lowcode-engine/tree/main/modules/code-generator)；
2. 修改example-schema.json内容为（**此内容使用Ice出码方案是可以执行的**）：`{"version":"1.0.0","componentsMap":[{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"Col","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextCol"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"Row","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextRow"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"RowColContainer","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextRowColContainer"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"BlockCell","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextBlockCell"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"Block","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextBlock"},{"package":"@alilc/lowcode-materials","version":"1.0.2","exportName":"NextText","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextText"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"P","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextP"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"PageHeader","main":"lib/index.js","destructuring":true,"subName":"","componentName":"NextPageHeader"},{"package":"@alifd/pro-layout","version":"1.0.1-beta.6","exportName":"Page","main":"lib/index.js","destructuring":true,"componentName":"NextPage"}],"componentsTree":[{"componentName":"Page","id":"node_dockcviv8fo1","props":{"ref":"outerView","style":{"height":"100%"}},"fileName":"/","dataSource":{"list":[{"type":"fetch","isInit":true,"options":{"params":{},"method":"GET","isCors":true,"timeout":5000,"headers":{},"uri":"mock/info.json"},"id":"info","shouldFetch":{"type":"JSFunction","value":"function() { \n console.log('should fetch.....');\n return true;

3. 为package.json增加一条script: `"rax": "node bin/lowcode-code-generator.js -i example-schema.json5 -o demo -s rax",`；
4. 运行rax命令，生成Rax代码，产出的代码层中有命名问题。需要将内容
`import {
Page as NextPage,
Block as NextBlock,
BlockCell as NextBlockCell,
RowColContainer as NextRowColContainer,
Row as NextRow,
Col as NextCol,
PageHeader as NextPageHeader,
P as NextP,
} from '@alifd/pro-layout/lib/index.js';`
**修改为**
`import {
Page,
Block,
BlockCell,
RowColContainer,
Row,
Col,
PageHeader,
P,
} from '@alifd/pro-layout/lib/index.js`;
5. 安装依赖后，运行Rax项目代码，会得到如下错误。
