**Description:**

[app-scripts] 'ionic-app-scripts' is not recognized as an internal or external command,

[ERROR] ionic-app-scripts has unexpectedly closed (exit code 1).

[app-scripts] 'ionic-app-scripts' is not recognized as an internal or external command,
[app-scripts] operable program or batch file.

**Steps to Reproduce:**

**Output:**

**My `ionic info`:**

```

```

**Other Information:**

npm 6.10.0
node 12.7.0
ionic cli 5.2.5
angular 5.2.11

i copies this project MAC to Windows already cordova build was added in mac so i copied now, i want to run my windows machine..
It's showing above errors

I already did these steps like
1.npm install @ionic/app-scripts@latest --save-dev
2.npm rebuild node-sass

No source file or test is named. Start by reproducing the Windows failure with Node 12.7.0, npm 6.10.0, Ionic CLI 5.2.5, and the copied project, then trace how the CLI invokes ionic-app-scripts. Done means the project builds successfully on Windows and the command-resolution failure is covered by a regression check.
