Desired behavior

ng update should proceed and update package.json and generate my
angular.json file etc

[malinges]

Same issue here, also on OS X.

After ng update @angular/cli, package.json ends up like this:

     "protractor": "~5.1.2",
     "ts-node": "~4.1.0",
     "tslint": "~5.9.1",
-    "typescript": "~2.5.3"
-  }
+    "typescript": "~2.5.,3" <-- comma inserted two characters too soon
+  "@angular-devkit/build-angular": "~0.6.0"
+    }
 }

I already noticed this two-character offset on angular 5.2 with ng commands like ng g.
Might be a schematics-related issue...?

I see this is fixed, how should I proceed? Trying cli 6.0.1 it still fails:

@hansl - see comment above. I don't have any files with BOM.

This issue still happening with @angular/cli 6.0.3

[DarthPinguin]

My tslint.json was empty, i added '{}' to have a valid json, ng update succeded after.

[JigneshPatel04]

same issue
when I run ng update @angular/cli
Updating karma configuration
Updating configuration
Removing old config file (.angular-cli.json)
Writing config file (angular.json)
Invalid JSON character: "" at 0:0.

[shanemac10]

I am following the steps to update from 5.2 to 6 on update.angular.io and ran into
a similar issue with ng update @angular/cli

...$ ng update @angular/cli
Your global Angular CLI version (1.7.4) is greater than your local
version (1.6.5). The local Angular CLI version is used.

To disable this warning use "ng set --global warnings.versionMismatch=false".
The specified command update is invalid. For available options, see ng help.

I wound up manually updating my package.json to cli version to my current version, saved it, ran npm install then ran ng update @angular/core (which is listed a few steps ahead of ng update @angular/cli on the website). During the the update core install I got this message...

The Angular CLI configuration format has been changed, and your existing configuration can
be updated automatically by running the following command:

ng update @angular/cli

... so I re-ran ng update @angular/cli and so far so good.

Hope this helps!
