【问题描述】：

我已经阅读了数百万个具有相同问题的线程，但我无法解决它:(

这是我做的一个旧项目，我需要再次访问它，但是在运行 npm start 时出现以下错误：

> express-typescript-starter@0.1.0 start
> npm run tsc && npm run serve


> express-typescript-starter@0.1.0 tsc
> tsc


> express-typescript-starter@0.1.0 serve
> ts-node src/server.ts

{"level":"debug","message":"Logging initialized at debug level"}

这是 src/config/passport.ts：

import passport from 'passport'
import { Strategy as JwtStrategy, ExtractJwt } from 'passport-jwt'
import userServices from '../services/userServices'
import { JWT_SECRET } from '../util/secret'

export const jwtStrategy = new JwtStrategy(
  {
    secretOrKey: JWT_SECRET,
    jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
  },
  async (payload: any, done: any) => {
    const userEmail = payload.email
    const foundUser = await userServices.findUserByEmail(userEmail)
    done(null, foundUser)
  }
)

我没有 .env 文件（我不需要，对吧？）

运行“npm i”时，我也遇到了一堆错误，但我可以 --force 它：

【解决方案1】：

您的import { JWT_SECRET } from '../util/secret' 不是正确的文件名。在你的仓库中它是https://github.com/AlanFPS/mern-finance-server/blob/master/src/util/seccret.ts。您的导入正在寻找 secret，但您的文件名为 seccret（两个 c）。

您还需要在根目录中放置一个 .env 文件，并确保它具有一个 JWT_SECRET 秘密值。

修改这些和/或也只是尝试使用 secretOrKey 的临时硬编码字符串，以便进一步调试此问题。
