Javascript 使用nodejs中的网站进行twitter身份验证时出错

我在实现twitter身份验证时遇到此错误

/home/jay/Documents/passport-twitter-master/examples/signin/node_modules/serve-favicon/index.js:38

  if (!path) throw new TypeError('path to favicon.ico is required');
                   ^
TypeError: path to favicon.ico is required

    at favicon (/home/jay/Documents/passport-twitter-master/examples/signin/node_modules/serve-favicon/index.js:38:20)

您需要在Express配置中设置favicon.ico文件，通常是app.js或server.js文件

该文件必须存在于磁盘上

var favicon = require('serve-favicon');
app.use(favicon(__dirname + '/public/favicon.ico'));
