Typescript 初始化Google Passportjs策略错误

我最近将一个服务器项目从javascript切换到了typescript，并且正在清理一些代码。我曾经把一些google passport Oauth的东西和登录路径保存在不同的文件中，但我决定将它们合并起来。在这个过程中，我破坏了一些代码，不明白为什么会发生错误或者如何修复它。提前谢谢

我知道错误发生在

server.express.use（auth.initialize（））

行的index.ts中。我收到错误

未处理的PromisejectionWarning:未处理的承诺拒绝（拒绝id:1）：TypeError:无法读取未定义的属性“initialize”

您能帮我找出我做错了什么吗

上下文。替换：

const initialize = passport.initialize
const session = passport.session

与：

要获得更多信息，请在
startServer
定义上方添加
console.log（auth）
，然后在抛出错误的行之前再次添加。@MattMcCutchen两个控制台日志产生相同的结果。控制台打印一个对象：
{routes:{//brevity}，initialize:[Function]，session:[Function]
@MattMcCutchen另外，如果我使用VSCode调试器进入initialize方法，最后一行包含
返回此值。\ u framework.initialize（此，选项）
而且_framework似乎是
未定义的
。很抱歉回复太晚，谢谢你的帮助，马特。思维棒极了马特。
