[vite] RollupError: Duplicate export 'default'

[tangerball]

const test = [
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
  ]

  test.forEach((module, index) => {
    console.log('🚀 ~ test.forEach ~ module:', module)
    if (index == 1) {
      module.test = 123
    }
  })

The above code example will have a packaging exception

It looks like module is treated as CommonJS's module. You can try replacing module with module1 or something.

const test = [
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
  ]

-  test.forEach((module, index) => {
+  test.forEach((module1, index) => {
    console.log('🚀 ~ test.forEach ~ module:', module)
    if (index == 1) {
      module.test = 123
    }
  })

It looks like module is treated as CommonJS's module. You can try replacing module with module1 or something.看起来module被视为 CommonJS 的module 。你可以尝试用module1或其他东西替换module 。

const test = [
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
    { test: 123, add: 123 },
  ]

-  test.forEach((module, index) => {
+  test.forEach((module1, index) => {
    console.log('🚀 ~ test.forEach ~ module:', module)
    if (index == 1) {
      module.test = 123
    }
  })

This example was written by a business developer. It is necessary to notify all developers to pay attention to this problem, which is too much of a burden. Can this problem be fundamentally fixed in the plug-in?
