Question

我看到这个问题已经问了很多遍了，但是没有一个答案符合我的情况：

技术：具有mysql node_module的node.js

节点代码：

app.get('/test', function(req, res) {
   var mysql = require('mysql');

   var con = mysql.createConnection({
      host: "localhost",
      user: "node",
      password: "myPassword",
      database : "myDatabase"
   });
con.connect(function(err) {
  if (err) throw err;
  console.log('CONNECTED');
});

错误：

[nodemon] app crashed - waiting for file changes before starting...

mysql工作正常：

root@www:/var/node# mysql -u node -p myDatabase
Enter password:

从命令行与mysql完全没有问题；但不适用于节点。

来自package.json

"dependencies": {
    "express": "^4.16.3",
    "mysql": "^2.16.0",
    "nodemon": "^1.18.3"
  },

为什么为什么...？哈哈
