connect ECONNREFUSED ::1:8011

该错误意味着您的程序试图连接到地址::1，这是一个IPv6地址，对应于localhost。然而，MongoDB并没有在IPv6地址上监听，而只在IPv4地址（即127.0.0.1）上监听。解决方案是在连接字符串中明确使用IPv4的地址。将原来的连接字符串中的localhost改为127.0.0.1即可解决该问题。例如，将mongoose.connect('mongodb://localhost:27017/d', { useNewUrlParser: true, useUnifiedTopology: true }) 改为mongoose.connect('mongodb://127.0.0.1:27017/d', { useNewUrlParser: true, useUnifiedTopology: true })。这样您的程序应该能够成功连接到MongoDB数据库了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
