构建在其他环境中是正常的，但在我的环境中发生了以下错误。

src/components/popup/CellInfoPopup.tsx:61:24 - error TS2786: 'NumberFormat' cannot be used as a JSX component.
  Its instance type 'NumberFormat<unknown>' is not a valid JSX element.

61                   <dd><NumberFormat value={meta.price} prefix="₩" thousandSeparator={true} displayType="text"/></dd>
                          ~~~~~~~~~~~~

src/components/popup/InvitationPopup.tsx:49:20 - error TS2786: 'CopyToClipboard' cannot be used as a JSX component.
  Its instance type 'CopyToClipboard' is not a valid JSX element.
    The types returned by 'render()' are incompatible between these types.
      Type 'React.ReactNode' is not assignable to type 'import("/Users/ksh/node_modules/@types/react/index").ReactNode'.

即使Node、Npm和yarn都重新安装，也会出现同样的错误，问题出在哪一部分？

React组件需要返回单个根元素，我有预感您的NumberFormat & CopyToClipboard组件有一个格式错误的return语句。
请确保您的组件没有像这样Map元素

function NumberFormat({ items }): JSX.Element {
        return items.map(item => (
            <>
                <li>{item.text}</li>
            </>
        )
    }

而是返回一个元素，如下所示：

function NumberFormat({ items }): JSX.Element {
        return <>{
            items.map(item => <li>{item.text}</li>)
          }</>
    }

该误差通常由以下两个因素之一引起：
1.您的组件是jsx元素的数组，而不是一个元素
1.返回jsx元素或null以外的值。
如果不是这两种类型中的一种，我相信不是，因为您说过构建在其他环境中是正常的，那么请尝试更新您的react类型：
纳米颗粒：npm install --save-dev @types/react@latest @types/react-dom@latestYarn：yarn add @types/react@latest @types/react-dom@latest --dev
如果您还想更新react和react-dom：
纳米颗粒：npm install react@latest react-dom@latestYarn：yarn add react@latest react-dom@latest
如果问题仍然出现，则尝试删除node_modules和package-lock.json并运行npm install
