I guess this is because the new project @ionic/v1-toolkit is required, perhaps you can update the error to mention this?

Thanks @jacquesdev

Yep, it's a bad error message.

$ ionic cordova build ios
ionic-v1 build
[ERROR] Command not found: ionic-v1

I am getting the same error.
What is the fix for this error?

[imhoffd]

npm i -D @ionic/v1-toolkit

I am working on an auto-installer prompt at this moment.

After using

npm i -D @ionic/v1-toolkit

i was successfully able to build my ionic v1 app in ionic CLI 4.0.2

thanks @dwieeb

There is an issue with node and the 'internal contextify script' : Assertion `args[1]->IsString()' failed

macOS High Sierra v10.13.5

$ npm -v
6.2.0
$ node -v
v10.7.0
$ ionic -v
CLI 4.0.2

$ ionic cordova build ios
> ionic-v1 build
ionic-v1[53011]: ../src/node_contextify.cc:635:static void node::contextify::ContextifyScript::New(const FunctionCallbackInfo<v8::Value> &): Assertion `args[1]->IsString()' failed.

@dave-k That looks like a different issue. Please create a new issue.

I had version 4.0.0 (updated the moment it came out) and had that bad error message.
I've run sudo npm i -g ionic@latest and re run my build command and got:

> ionic-v1 build

[INFO] Looks like @ionic/v1-toolkit isn't installed in this project.
       
       This package is required for this command to work properly.

? Install @ionic/v1-toolkit? Yes
> npm i -D -E @ionic/v1-toolkit

AWESOME!

P.S. shouldnt it use --save? (so that it works in the future....)
