我尝试使用链接https://code.visualstudio.com/docs/nodejs/reactjs-tutorial创建反应应用 但是当我运行命令时，我得到以下错误
create-react-app my-app

我有同样的错误，但是语法不同。
尝试使用 protected X509Certificate verifyClientCertificate(HttpServletRequest req) {
X509Certificate[] certs = (X509Certificate[]) req.getAttribute("javax.servlet.request.X509Certificate");
if (null != certs && certs.length > 0) {
return certs[0];
}
// ....
throw new RuntimeException("No X.509 client certificate found in request");
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException {
System.out.println("DO POST");
verifyClientCertificate(request);
super.doPost(request, response);
}
或VSCode终端，在cmd中创建您的react应用。由于我认为尝试以长路径（C:\Users\thirunah）创建react应用时存在问题。
因此，转到C:\Users\thirunah\Documents\Visual Studio Code\my-app，cmd（C:\Users\thirunah）并写
cd C:\Users\thirunah在此之前，请确保已安装create-react-app Your-app-name
和node。
您可以从node.js安装节点，并在create-react-app中编写
