MissingDriverError lorsque le type est oracle: en utilisant typeorm

Question

J'utilise typeorm en JavaScript pour le noeud et back-end express comme ici:
https://typeorm.github.io/usage-with-javascript.html

version noeud v6.11.1
dipendencies de 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" 

Ce

est l'erreur que je reçois:

Error: { Error

     name: 'MissingDriverError', 
     message: 'Wrong driver undefined given. Supported drivers are: "mysql", "postgres", "mssql", "oracle", "mariadb", "sqlite".' } 

Voici le m odel:

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

Voici le code où je suis en train d'accéder à la base de données:

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); 
    }); 
    } 

Qu'est-ce que je fais mal?

Answer 1

Avez-vous effectué l'étape d'installation du pilote? https://typeorm.github.io/index.html#installation

Voir ce pour plus de détails sur l'installation de nœud-oracledb: https://github.com/oracle/node-oracledb/blob/master/INSTALL.md

Answer 2

On dirait que j'utilisais la dernière version de typeorm (0.1.0-alpha.35) lorsque j'ai enlevé et installé que la version stable (0.0.11) les erreurs sont parties!

mais maintenant je ne peux pas utiliser la connexion d'une certaine manière, je reçois l'erreur suivante quand je fais

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

à la connexion

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

SyntaxError: Unexpected identifier

merci pour l'aide!
