1. Mention any other details that might be useful.

When I set a new project with ng new foo --link-cli, the problem doesn't occur.
I have done npm link angular-cli on the old one.

It doesn't work under /var/www/html/public but it does under /home/myuser
Is it because angular-cli is cloned under my user folder ?

It works when i copy the cloned folder under my project node_modules folder

I have the same issue on Mac OS X Yosemite.

[rokde]

The same on:

• angular-cli: 1.0.0-beta.14
• node: 6.4.0
• os: linux x64

[divid3byzero]

I have the same issue with if angular-cli is installed globally:

• angular-cli: 1.0.0-beta.15
• node: 6.4.0
• os: darwin x64 (El Capitan 10.11.6)

Works if the CLI ist installed locally. Possibly some rights issue? Even though the error would then probably be somehow different...

[joao-fidalgo]

Having the same issue.

[Djuki]

Same issue:

angular-cli: 1.0.0-beta.15
node: 6.6.0
os: linux x64

[MartinNuc]

Same issue.

angular-cli: 1.0.0-beta.15
node: 6.6.0
os: darwin x64

Same on Mac os El Capitan:

angular-cli: 1.0.0-beta.15
node: 6.6.0
os: darwin x64

[brianmadden]

Same issue.
angular-cli: 1.0.0-beta.15
node: 4.2.6
os: Ubuntu 16.04 x64

Additional details: Created the project on my laptop (also Ubuntu 16.04, angular-cli 1.0.0-beta.15, node 4.2.6) and it built/served fine. This failure occurs on my desktop after git cloneing the repo.

Edit: Ran a git clean -dfx followed by npm install followed by ng serve and it seems to be working now. I'm guessing there was some leftover stuff in the directory from prior to migrating my project to use angular-cli.

@brianmadden Thank you so much! this worked for me

[ewu-youngb]

@brianmadden Thanks, that helped!

For us this happens when we give the node_modules as symlink instead of a folder inside the source. Presumably the webpack tries to include node_modules/.. into the sourcemap.
Since it is a symlink app/node_modules/.. is not actualy the same as app/ so the app directory is not included in the sourcemap.

I'm having some trouble understanding this issue. So this happens when using the master branch directly, right? What else are you doing? Can you give me very explicit instructions for me to repro it?

I use the master branch every day and haven't ever seen this happen, so I'm wondering what the setup is, and how it differs from mine.

[brianmadden]

I think my case was caused by re-using an existing directory for my project. When I initially set the project up I re-used my existing project directory. Prior to initializing the cli project I did a rm -rf * in the project directory and everything worked on that computer.

I then pushed to github and pulled on my laptop. This is where I believe things went wrong. There were files left over on my laptop from the old project, but they weren't tracked by git so weren't deleted when I pulled. I think the problem was the lingering files, and this is why the git clean and re-run of npm install fixed the issue for me.
