Problem with knex-migrator

Developer help Installation

I have a problem with migration from 2.22 to 2.23.2 and knex-migrator 3.3 on node.js v10.13:

lib/node_modules/knex-migrator/bin/knex-migrator-migra
te:9
utils.getKnexMigrator({path: process.cwd()})
^

TypeError: utils.getKnexMigrator is not a function

Hi @Peleke! How exactly are you running into this problem? Are you using ghost-cli to update your blog instance? At what point is this error happening? Could you please provide a more reproducible scenario to get this error? Cheers!

Yes, sure. I am running Ghost self-hosted and I am using this script to update it: Ghost 3 auf Uberspace 7 per Script aktualisieren | Pelekes Blog
I didn’t change anything to the script for a while and it worked as it should for a lot of updates already.
Could it be an issue of the new knex-migrator 3.3 that I have updated before the Ghost update? This version is not yet listed on GitHub but available already on npm.

Could it be an issue of the new knex-migrator 3.3

This is interesting. Could you check if it works with an earlier version of knex-migrator?

I just applied the same procedure as the last time but with knex-migrator 3.2.6 instead of 3.3.0 to update ghost from 2.23.2 to 2.23.3 and it worked as it should. So it seems to be an issue with knex-migrator 3.3.0

6

This is an interesting lead. I will try to have a closer look at it on Monday. Would really appreciate if you could be able to track it down to some more specific point :raised_hands: The tests are still passing on the latest version, but now I’m a bit dubious about bumping the version in Ghost core :thinking:

Is the above error message not helpful? Is there a way to turn on verbose or debug mode?

Hey @Peleke! Version 3.3.1 of knex-migrator has been released. Let me know if everything works as expected now :wink:

Hi @naz, I just updated Ghost from 2.23.3 -> 2.23.4 with knex-migrator 3.3.1 and now it shows a different error:

ERROR Cannot find module '../migrations'

Cannot find module '../migrations'

Error Code: 
    MODULE_NOT_FOUND

It seems that it is still not solved. Should I open a new ticket or do you want to re-open the existing one?

No need to reopen the issue, the fix is too trivial. I will reference the closed one and release a new minor in a bit :+1: Tested the package locally with yarn link and now I know one of the downsides of this approach :slight_smile:

11

Released 3.3.2 :tada:

Thanks, that works as it should again, problem solved. :grinning:

One question about updating knex-migrator:

Should I use

npm install -g knex-migrator

or

npm update -g knex-migrator

After reading node.js - npm install vs. update - what's the difference? - Stack Overflow I wasn’t sure which method is better in this case (or if it matters at all).

13

Think when using in global context -g it’s safest using npm install because of this reason:

set them as global (which puts them in the shell’s PATH)
