Wijmo导出Excel失败
本帖最后由 user99999 于 2024-12-19 17:05 编辑问题：
1. 子系统使用wijmo导出excel时，页面报错，具体报错如下：
2. 当在子系统中单独引入jszip: 3版本后，子系统本地开发环境正常，测试环境报错，具体报错如下：
子系统导出Excel定义代码如下，2个问题导出方法均未改变
import * as gridXlsx from '@grapecity/wijmo.grid.xlsx'
downloadExcel(filename: string) {
const book = gridXlsx.FlexGridXlsxConverter.saveAsync(this.pivotGrid, {
includeColumnHeaders: true,
includeRowHeaders: true
})
book.saveAsync(`${filename}.xlsx`)
}
背景：
1. 子系统使用wijmo开发，并嵌入到microApp基座中，子系统并没有单独引入jszip，基座加载jszip代码如下
- 基座拷贝一份jszip代码放在基座中
- 通过<script src="/jszip.min.js"></script>加载到HTML模板中- 基座在package.json中安装"jszip": "^3.10.1"
- 基座通过vite拆包 optimizeDeps: { exclude: ['@grapecity/wijmo.xlsx', 'jszip'] }- 基座设置jszip
import * as wXlsx from '@grapecity/wijmo.xlsx'
wXlsx.useJSZip(window.JSZip)
window.wXlsx = wXlsx
- 基座设置jszip2. 子系统中各wijmo版本如下
"@grapecity/wijmo": "~6.20880.670",
"@grapecity/wijmo.all": "^6.20880.673",
"@grapecity/wijmo.grid": "~6.20880.673",
"@grapecity/wijmo.grid.xlsx": "~6.20880.673",
"@grapecity/wijmo.olap": "~6.20880.673",
"@grapecity/wijmo.react.input": "~6.20880.670",
"@grapecity/wijmo.react.olap": "~6.20880.673",
"@grapecity/wijmo.styles": "~6.20880.670",
"@grapecity/wijmo.xlsx": "~6.20880.670",
请帮忙分析问题原因，并给出解决方案，非常感谢
“当在子系统中单独引入jszip: 3版本后，子系统本地开发环境正常，测试环境报错”
请给一个能复现问题的demo项目。你提到的测试环境如何复现？是否是项目编译后部署就会报错？
使用的就是官方提供的标注导出方法，即官方导出Excel文档：

测试环境：webpack编译后的生产环境，本地环境：未编译前的本地开发环境 你是用提到的
https://demo.grapecity.com.cn/wijmo/demos/OLAP/PivotGrid/Export/Excel,PDF,CSV/purejs
这个demo下载后，在没有做过修改的情况下编译后就能复现报错的吗？
如果不是的话，还是请提供一个demo项目，从你的描述来看和引用的版本，依赖，以及webpack的版本，配置等等都有可能有关系。 使用上面链接中的官方demo就会报错，报错信息，项目背景，可以看之前描述：

子项目没有单独引入JSZIP，但是基座有引入并处理，处理方式见1楼背景描述，项目中加载过程如下：
请看我上一个回复，让你提供的完整的demo项目的原因是，我们没有办法完全还原你说的这些环境，只有代码是没有用的，从你的描述里，是把在线demo中的代码放到你的项目中才会报错
你需要提供一个可以编译运行的demo项目来复现所说的问题，否则我们无法调查原因
而且你引用的"6.20880.673"是哪个版本，这个版本是完全没有的。
