/bin/sh: yo: command not found

[katopz]

Somehow I got this error on my macOS

$ create-graphql generate --mutation Awesome
✗ GraphQL CLI requires Yeoman to be installed.
✓ Yeoman installed!
/bin/sh: yo: command not found
(node:37016) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Exited with status 127

FYI

$ node --version
v7.4.0

Any hint?

[lucasbento]

Hmm, how did you install create-graphql on the first place? Using yarn or npm?

Can you check if yo (yeoman) is installed on your machine?

[katopz]

Oh! it work after I manually npm install -g yo (I use npm way) At first I think ✓ Yeoman installed! should install yeoman for me already like it said. 🤕

[lucasbento]

That's what it is supposed to do, it actually just trigger a npm install -g yo while you are trying to generate a file.

Do you have yarn installed? If you do, what version is it?

[katopz]

Somehow yes but I rarely use it, it's 0.17.10

[felippepuhle]

Maybe the path variable isn't being updated?

[lucasbento]

The problem is probably with yarn itself, since it is already on version 0.19.1.

create-graphql checks if you have yarn installed, if you do, it uses it, otherwise it goes with npm.

Perhaps it's better to remove that checking for now and go with npm only, what do you guys think?

[katopz]

I think I mess thing up already when try to uninstall yarn

cat:mongoose-role-example katopz$ yarn --version
0.17.10

cat:mongoose-role-example katopz$ npm r -g yo
- abbrev@1.1.0 node_modules/yo/node_modules/abbrev

Sorry! 😭

[sibelius]

@katopz I recommend u to use NVM to manage your node versions, it can solve your problem

[lucasbento]

@katopz: it's weird, you uninstalled yarn but it's still on your path.

Can you try hitting which yarn on command-line?

I think we can remove that yarn/npm checking, a lot of users are having problem with yarn :/

[felippepuhle]

I can work on it, if you guys want...

[lucasbento]

I think it's the best we can do right now, yarn itself is not stable yet and a lot of people are using old versions.

To remove the yarn checking, simply change this part, @felippepuhle, and then we can make a release for it.

[sibelius]

can't we try to install yeoman using yarn and check if yeoman was installed successful, if not we install using npm

[lucasbento]

@sibelius: that sounds like an ugly workaround, I wouldn't like that any tool did so.

[lucasbento]

@katopz: we just released 1.1.16 with @felippepuhle's #76 PR, would you mind checking if it works for you?

[katopz]

@lucasbento LGTM no more error with or without yarn

BTW, I think I've 2 yarn, one from brew and one from npm Sorry for the mess!

Thanks

[lucasbento]

Yeah, we removed yarn for now, it's not stable yet and not a lot of people have it working.

Don't hesitate on opening a new issue if you need, @katopz.
