# Bitrise Build Issue Report template
## Description of the issue
Ionic build fails after installing Cordova:
\> cordova platform add ios --save
Using cordova-fetch for cordova-ios@4.5.5
Adding ios project…
Creating Cordova project for the iOS platform:
Path: platforms/ios
chmod: File not found: /Users/vagrant/git/platforms/ios/cordova/node\_modules/.bin/ios-sim
## Environment:
Bitrise stack: `Xcode 9.4.x`
If on [Bitrise.io](http://Bitrise.io): which stack? If not on [Bitrise.io](http://Bitrise.io): on what operating system? (Plus any other information you can share)
Ionic Build iOS
E.g.: Git Clone v3.6.0
## Reproducibility
- _Does a “Rebuild” help? (You can trigger a rebuild from the Build’s page, by clicking the “Rebuild” button in the top right corner of a finished build)_ : YES
- _Does a rebuild without caches help? (You can remove the `Cache:Pull` and `Cache:Push` steps temporarily to not to use the cache, or [you can delete all the caches on the `Settings` tab of the app](http://devcenter.bitrise.io/caching/about-caching/#downloading-and-deleting-caches)._ : NO
- _Does the issue happen sporadically, or every time?_ : every time
- _Does upgrading the build Step to the latest version help?_ : NO
- _When did the issue start?_ : last week
### Local reproduction
_Can it be reproduced on your own Mac/PC by following our [local debug guide](http://discuss.bitrise.io/t/how-to-debug-your-build-locally-it-works-on-my-mac-pc-but-not-on-bitrise-io/392)? Please follow at least the first section (“Testing with a full clean git clone”) to make sure to test the state of the code what [bitrise.io](http://bitrise.io) will get when it does a git clone in the clean environment! If possible please note which sections you tried._
### Local reproduction: Linux / Android (docker based) stack builds
_Can it be reproduced by running the build locally, after doing a new git clone of the repository into the `/tmp` directory and running the build from there with the Bitrise CLI ( [https://www.bitrise.io/cli](https://www.bitrise.io/cli) )? If no, can it be reproduced with Docker (using the same docker images / environment we use on [bitrise.io](http://bitrise.io))? Related guide: [http://devcenter.bitrise.io/docker/run-your-build-locally-in-docker/](http://devcenter.bitrise.io/docker/run-your-build-locally-in-docker/) ._
## Build log
_Please copy paste the build’s [bitrise.io](http://bitrise.io) URL here (or if the issue happens somewhere else then the full logs), or if you can’t share the url / log here then send the url or full log through a private channel (e.g. email - [https://www.bitrise.io/contact](https://www.bitrise.io/contact) ), with a link to the related Discuss issue._

Hello @alonrosenfeld!
it seems that a npm package is missing calles ios-sim, and I am pretty sure that you did not use it knowingly.
I think some third party dependency change is the cause of this error. I would suggest installing ios-sim first and see what happens.
