MissingDriverError當類型爲oracle：使用typeorm

Question

我使用typeorm在JavaScript中的節點和快速的後端喜歡這裏：
https://typeorm.github.io/usage-with-javascript.html

節點版本v6.11.1
dipendencies從的package.json

"@types/es6-shim": "^0.31.35", 
    "@types/node": "^8.0.25", 
    "async": "^2.5.0", 
    "body-parser": "^1.17.2", 
    "cors": "^2.8.4", 
    "express": "^4.15.4", 
    "oracledb": "^1.13.1", 
    "reflect-metadata": "^0.1.10", 
    "typeorm": "0.1.0-alpha.35" 

這是我得到的錯誤：

Error: { Error 
     at new MissingDriverError (C:\Users\shodh\projects\NAPPATracking\node_modules\typeorm\error\MissingDriverError.js:22:23) 
     at DriverFactory.create (C:\Users\shodh\projects\NAPPATracking\node_modules\typeorm\driver\DriverFactory.js:40:23) 
     at new Connection (C:\Users\shodh\projects\NAPPATracking\node_modules\typeorm\connection\Connection.js:81:59) 
     at ConnectionManager.create (C:\Users\shodh\projects\NAPPATracking\node_modules\typeorm\connection\ConnectionManager.js:56:26) 
     at Object.<anonymous> (...\node_modules\typeorm\index.js:205:70) 
     at step (...\node_modules\typeorm\index.js:32:23) 
     at Object.next (...\node_modules\typeorm\index.js:13:53) 
     at ...\node_modules\typeorm\index.js:7:71 
     at __awaiter (...\node_modules\typeorm\index.js:3:12) 
     at Object.createConnection (...\node_modules\typeorm\index.js:196:12) 
     name: 'MissingDriverError', 
     message: 'Wrong driver undefined given. Supported drivers are: "mysql", "postgres", "mssql", "oracle", "mariadb", "sqlite".' } 

這裏是m奧德爾：

module.exports = { 
    name: "reagentsandconditionsnames", 
    columns: { 
     reagentnameid: { 
      primary: true, 
      type: "int", 
      generated: true 
     }, 
     reagentname: { 
      type: "string" 
     }, 
     datatype: { 
      type: "string" 
     }, 
     displayordernumber: { 
      type: "int" 
     } 
    } 
}; 

這裏就是我試圖訪問數據庫的代碼：

var typeorm = require("typeorm"); // import * as typeorm from "typeorm"; 
const oracledb = require('oracledb'); 
var reagentsandconditionsnames = require("./reagentsandconditionsnames"); // import {Post} from "./model/Post"; 
module.exports.getAllRandC = (callback) => { 
    typeorm.createConnection({ 
     driver: { 
      type: "oracle", 
      host: "localhost", 
      port: 1521, 
      username: "uname", 
      password: "pwd", 
      database: "dev" 
     }, 
     entitySchemas: [ 
      reagentsandconditionsnames 
     ], 
     autoSchemaSync: true 
    }).then(function (connection) { 
     console.log(connection); 
     // let rncnames = await connection.entityManager.find(reagentsandconditionsnames); 
     // console.log(rncnames); 
     callback(null, JSON.stringify("rncnames")); 
     }).catch(function(error) { 
     console.log("Error: ", error); 
    }); 
    } 

我在做什麼錯？

Answer 1

你做的驅動程序安裝步驟？ https://typeorm.github.io/index.html#installation

見本有關安裝節點OracleDB的細節： https://github.com/oracle/node-oracledb/blob/master/INSTALL.md

Answer 2

看起來像我用的是最新版本typeorm（0.1.0-alpha.35）當我刪除，並安裝了穩定版（0.0.11）錯誤消失了！

，但現在我不能以某種方式使用的連接，我得到以下錯誤，當我做

let rncnames = await connection.entityManager.find(reagentsandconditionsnames); 

在連接

let rncnames = await connection.entityManager.find(reagentsandconditionsnames); 

SyntaxError: Unexpected identifier

感謝您的幫助！
