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.

it’s an NPM flag, you can do ng new ProjectName --skip-npm and then npm install --no-bin-links

Having the exact same issue building a docker image. Using Node:6.7.0 and CLI:1.0.0-beta.19-3. It works fine in dev mode but when I change NODE_ENV=production, $ ng build, fails with the following error:

/usr/lib/node_modules/angular-cli/node_modules/webpack-sources/node_modules/source-map/lib/source-map-consumer.js:704 throw new Error(‘"’ + aSource + ‘" is not in the SourceMap.’);
