因此，当我尝试使用 Docker 运行我的应用程序时，Typescript 会引发编译错误时，我会遇到这个奇怪的错误。当我在我的计算机上本地运行它时，不会发生此错误。

我的 Dockerfile

FROM node:alpine

WORKDIR /app

COPY package.json .
RUN npm install --only=prod
COPY ./ ./

CMD ["npm", "start"]

包.json

}

错误

这些是 Typescript 抱怨的代码。显然，Typescript 期望“done()”回调有 1 个参数，这是没有意义的。

userSchema.pre('save', async function (done) {
  if (this.isModified('password')) {
    const hashed = await Password.toHash(this.get('password'));
    this.set('password', hashed);
  }
  done();
});
