我在构建步骤中在node_module中获得了多个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软件包版本有关，所以我发现一个使用相同软件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它，它确实有效！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并重新安装它们。虽然它也没有解决问题。
我目前的设置是：
package.json：

我前一段时间遇到了同样的问题，它与./node_modules/@types无关。使用nvm - 节点版本管理器并完成对node，npm，yarn及其全局软件包的删除修复了我的问题。
卸载Node.js和NPM需要相当a lot of steps，这就是为什么我建议使用node-reinstall script等自动化解决方案。
git clone [email protected]: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，并将其替换为节点版本管理器。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，那么只需执行brew uninstall yarn，否则yarn已经从您的系统中删除。
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，一切都被删除了，你准备用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。 现在检查一切：
node -v
npm -v
