前言

组件发布之后使用可能会遇到报错，错误信息：Uncaught TypeError:Cannot read properties of null (reading ‘isCE’)
at Cc (1cl-test-ui.mjs:1564:9)

一、如何解决

在vite.config.js中添加代码

rollupOptions: { //解决isCE
      external: ["vue"],
      output: {
        globals: {
          vue: 'vue'
        }
      }
    },

    rollupOptions: { //解决isCE
      external: ["vue"],
      output: {
        globals: {

        }
      }
