Ch13: Cannot read property 'Store' of undefined

[yejia4869]

Hi Ethan

The book is very easily to understand and attracts me to learn deeply.
but I stuck in ch13 by the following error:

../meadowlark/node_modules/session-mongoose/index.js:266
})(connect.session.Store);
....................^
TypeError: Cannot read property 'Store' of undefined

Initially, I thought it was the problem of "session-mongoose", so I searched this package on npmjs website and
found this:

IMPORTANT: This module currently supports legacy versions of connect (2.x) and express (2.x and 3.x) due to extensive changes made to those modules.
Until support for latest modules are added, this module should not be used with latest versions of connect and express.

However, when I managed to install [email protected] in my project, I found the [email protected] series is deprecated. It got me...

Am I missing something? Any way to improve this?

Hi, @yejia4869; I'm glad you're enjoying the book...sorry you're encountering issues.

Unfortunately, the content is pretty significantly out of date at this point. I do have a second edition on the way, but it probably won't hit the shelves until Q2 2019 (early releases sooner, I imagine).

Without diving into this more deeply, I'm afraid all I can suggest is that you install the exact version numbers listed in ch13/package.json.... In other words, when you install them, do it like this:

$ npm add [email protected]
$ npm add [email protected]
$ ...

And so on...let me know if that doesn't solve the problem....

(Note that chai in the dependencies should really be in the dev dependencies. Doesn't hurt anything, but oops!)

@LeThao98 the problem is exaclty using the latest connect/express. Please try with the explicit versions in the repo package.json file, per my comment above....
