just hangs!
even I started with sudo

After many try, ng update @angular/cli ends with a bug below:

Mine hangs for a few minutes then outputs the following:

503 Service Unavailable

Is there a verbose option? Would be nice to see what it's doing under the hood.

[MonsieurMan]

Hangs forever without any output in my case.

I am getting a hang as well. Finished with a connection timeout.

I was having this errors but now it worked here after running VSCode as administrator in Windows environment. Git bash is default terminal.

Junior@MYPC MINGW64 /c/Projects/SampleApp.SPA (master)
$ ng update @angular/cli
Your global Angular CLI version (6.1.1) is greater than your local
version (1.7.4). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Junior@MYPC MINGW64 /c/Projects/SampleApp.SPA (master)

The error was happening in third step (from angular 5.2 to 6.0):

1. npm install -g @angular/cli
2. npm install @angular/cli
3. ng update @angular/cli

I also was having problems when trying to rerun npm install @angular/cli at step two, so I had to specifiy the version

npm install @angular/[email protected]

the installation worked
and also worked

$ ng update @angular/cli
            Updating karma configuration
            Updating configuration
            Removing old config file (.angular-cli.json)
            Writing config file (angular.json)
            Some configuration options have been changed, please make sure to update any npm scripts which you may have modified.
DELETE .angular-cli.json
CREATE angular.json (4627 bytes)
UPDATE karma.conf.js (962 bytes)
UPDATE src/tsconfig.spec.json (303 bytes)
UPDATE package.json (1740 bytes)
UPDATE tsconfig.json (407 bytes)
UPDATE tslint.json (2998 bytes)

I do not know if it has something to do with permissions, an intermitent timeout or a bug in npm install which goes crazy when you do not add the target angular version.

@allanbond you are right! Where is the verbose option? My angular update is stuck and i don't see any logs.

I also experienced this issue when upgrading from Angular 5 to Angular 6. On my internet connection i.e. 2 MB/s it took half an hour but no result and then I increased my internet speed to 50 - 60 (MB/s) at this speed it took hardly 5 - 10 mins to run update command. Overall ng update is working but it seems that nothings happening so wait and let NG do its work. Hope it help you 👍

[samends]

Just want to chime in here to say I'm getting hanging as well when I run ng update @angular/cli@6 going from angular version 5.2.0 to 6.1.1. Specifically I run:

npm install @angular/[email protected]
npm update @angular/cli

The console hangs without displaying anything. I'm using windows 10

Numerous improvements have been made to the ng update command since version 6.0. If anyone is still encountering issues with the update command on 5.x/6.x, please consider updating to a newer version via npm/yarn and then manually executing the update migrations ng update --migrate-only --from=<original_version>.
