Same issue as #1562 please close it or mark it as duplicate....

[jthoms1]

_From @cimenx on October 22, 2016 6:18_

@tlambrou i solve this by adding ionic-app-scripts to the project
npm install @ionic/app-scripts@latest --save-dev

[jthoms1]

_From @rodrigograca31 on October 24, 2016 11:51_

Didn't solve the problem in my case....
It was @ionic/[email protected] and stayed the same...

[jthoms1]

_From @tlambrou on October 25, 2016 3:3_

In my case it appears that the problem was related to having my ionic app running in a folder that was synced to cloud services (Dropbox, iCloud). After moving the directory to a non-synced folder, things began working again. # #

_From @rodrigograca31 on October 25, 2016 10:25_

@tlambrou That doesn't make sense.... Can you confirm that?
I have my project on a "non-synced folder" and tried to move it to another folder and didn't help...

[danbucholtz]

@tlambrou,

Glad you were able to get it resolved. @rodrigograca31, any updates on this? This is unexpected and we need more info to troubleshoot.

For now, I am going to close this. Will re-open if needed.

Thanks,
Dan

[rodrigograca31]

@danbucholtz No, I've not solved the problem.... What info do you need?

Since you guys move this issue I nee to add again that this is the same problem as #253

Running these commands again still creates the same problem:

ionic start app4 --v2
cd app4
ionic run android
cordova platform add android
ionic run android

I tough we could already create apps using Ionic 2 but apparently not....

[danbucholtz]

@rodrigograca31,

Please give me some output or error information. Right now I have literally nothing to work off of.

Thanks,
Dan

[rodrigograca31]

@danbucholtz "I have literally nothing to work off of." What? If you scroll up there's the error information.... On the issue it self.... and as I mentioned before it's the same problem as #253 so my own output is on #253 this was a duplicated issue..... but....

[danbucholtz]

@rodrigograca31, See my comment here.

Thanks,
Dan

Hi!

Just to let you guys know, I was facing the same problem (sh: ionic-app-scripts: command not found) in my macbook, and I managed to solve this problem running yarn instead of npm install. You might have to use sudo.

Cheers!

@jthoms1,

What do you think of the above issue?

Thanks,
Dan

[ngrealish]

I had this same issue. I found that when I initialized my app, I did so in terminal. So I had already run Ionic serve. The server was running but I could only tell in the terminal app. I then went into my IDEA (IntelliJ) and tried to run ionic serve in the terminal there. I then go the same error you showed above.

After fiddling, I noticed it was already running... silly me.

[MadhavBitra]

@ionic/app-scripts@latest --save-dev has worked for me
