node_modules/@types/ 错误（接口“元素”不能同时扩展类型“ReactElement<any>）答案

【问题描述】：

在构建步骤中，node_module 中出现多个 React.js 类型错误：

TS2320: Interface 'Element' cannot simultaneously extend types 'ReactElement<any>' and 'ReactElement<any>'. Named property 'type' of types 'ReactElement<any>' and 'ReactElement<any>' are not identical.
S2320: Interface 'ElementClass' cannot simultaneously extend types 'Component<any, {}, any>' and 'Component<any, {}, any>'. Named property 'props' of types 'Component<any, {}, any>' and 'Component<any, {}, any>' are not identical.
TS2300: Duplicate identifier 'LibraryManagedAttributes'.
TS2717: Subsequent property declarations must have the same type. Property 'a' must be of type 'DetailedHTMLProps<AnchorHTMLAttributes<HTMLAnchorElement>, HTMLAnchorElement>', but here has type 'DetailedHTMLProps<AnchorHTMLAttributes<HTMLAnchorElement>, HTMLAnchorElement>'.

起初我认为问题与未修复的包版本有关，所以我找到了一个使用相同包的工作项目并编辑了我的package.json 文件以使用确切的版本。 - 没有帮助。

然后我让我的同事在他的机器上做这件事，它确实奏效了！所以我调整了node、npm 和yarn 以匹配相同的版本。 - 没有帮助。

之后，我完全删除了node、npm、yarn 并重新安装了它们。 虽然它也没有解决问题。

我目前的设置是：

节点 v10.9.0
npm v6.2.0
yarn v1.9.4

package.json:

    "react": "^16.4.2",
    "react-dom": "^16.4.2",

  }

tsconfig.json:

【解决方案1】：

我前段时间遇到过同样的问题，与./node_modules/@types无关。使用nvm - 节点版本管理器并彻底清除node、npm、yarn 及其全局包解决了我的问题。

卸载 Node.js 和 NPM 需要花费很多 a lot of steps，这就是为什么我建议使用自动化解决方案，例如 node-reinstall script。

git clone git@github.com:brock/node-reinstall.git
cd node-reinstall
./node-reinstall

这将删除所有包并完全删除 Node.js 和 NPM，并将其替换为 Node 版本管理器。如果安装成功，您将能够看到如下内容：

nvm --version // 0.33.11

如果您使用 Homebrew 安装 yarn，则只需执行 brew uninstall yarn，否则 yarn 已从您的系统中删除。

现在你必须照顾yarn packages。 cd 到 ~/.config/yarn/global 并删除 node_modules、package.json 和 yarn.lock。

就是这样，所有内容都已删除，您可以使用nvm 安装 Node 和 NPM。为此，请键入：

 nvm install node

它将下载、编译和安装最新版本的 Node 和 NPM。
现在检查所有内容：

node -v
npm -v
