Cypress:无法安装二进制文件

我正在尝试使用二进制安装 cypress。目前在 vs code 中使用以下命令:CYPRESS_INSTALL_BINARY=C:\Users\abcd\Downloads\cypress.zip npm install cypress

来源:https ://docs.cypress.io/guides/getting-started/installing-cypress.html#Install-binary

这对我不起作用,显示以下错误:

CYPRESS_INSTALL_BINARY=C:\Users\abcd\Downloads\cypress.zip : The term 'CYPRESS_INSTALL_BINARY=C:\Users\abcd\Downloads\cypress.zip' is not recognized as the name of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

这里我只是通过.jsp文件输入用户名和密码,并在不同的行中打印用户名和密码.

package pack123;
public class Loginpg extends HttpServlet{

    public void service (HttpServletRequest request, HttpServletResponse response){
        PrintWriter pw=response.getWriter();
        String username=request.getparameter("uname");

    }
