import FileSaver from 'file-saver' import XLSXStyle from "xlsx-style"; import XLSX from 'xlsx' vue 2.0版本xlsx-style ./cptable' 报错:Can't resolve './cptable' in 'xxxx\nautical-front\node_modules_xlsx 解决办法
1根据脚手架版本不同可以在 webpack.base.conf.js 中写
module.exports = {
externals: [ {
'./cptable': 'var cptable'
}]
}
也可以在vue.config.js中写
module.exports = {
chainWebpack: config => {
config.externals({ './cptable': 'var cptable' })
}
}
问题所在：\node_modules\xlsx-style\dist\cpexcel.js 807行 var cpt = require('./cpt' + 'able');
修改为 var cpt = cptable 修改的只是本地文件
不推荐这种方式，因为你只是修改了自己的本地文件呢，下一次其他人进行打包或运行项目一样会报这类错误
