sequelize-cli non-functional @node7.0.0

[awitherspoon]

Using sequelize with the latest version of node throws the following error:

Sequelize [Node: 7.0.0, CLI: 2.4.0, ORM: 3.24.6]

module.js:474
    throw err;
    ^

This seems to be related to a bad version of graceful-fs, as noted in this npm issue

Needless to say, the expected behavior was that updating the package would allow for it to work inside node7.0.0. It seems that the graceful-fs package being used by sequelize-cli needs to be updated.

getting this too.

It looks like this is tied to the version of Gulp being used, and Gulp 4.0 seems suited based on version number of the package vinyl-fs. That being said, it's also not a fully released build yet, and so would certainly require testing to ensure it will work as expected in sequelize-cli.

npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.

And the 'npm ls graceful-fs' result is:

sequelize-cli@2.4.0
├─┬ fs-extra@1.0.0
│ └── graceful-fs@4.1.10

Gulp is using graceful-fs < v4. It needs to update before this can be used in node v7..

Looks like another reason for #344

I'm having pretty much the same issue with node 7.7.1 on windows 10, except that i'm not getting any errors, but the cli does not execute any command, not even help. It only shows

Sequelize [Node: 7.7.1, CLI: 2.4.0, ORM: 3.30.2, mysql: ^2.13.0]

Switching to node 6.7.0 via nvm makes it functional again.

I've just test it on ubuntu 16.04 with the same version of node and it seems to be working

Has anyone found a workaround for this other than switching to node 6.7.0 via nvm?

I can confirm this is an issue in Node 8 as well. @janmeier do you have any thoughts on how we can fix this? Node 8 is going into LTS soon so this will become a bigger problem.

It looks like maybe a Gulp upgrade would fix it? nodejs/node#9355 (comment)

Same issue in Node 8 as well

CLI doesn't depend on Gulp any more, so this should be fixed now
