Adding the aurelia-configuration to a cli application sometimes produces a build error. This is caused by a missing dependency so we simply add the dependency to the build bundle.
Try the following:
npm install deep-extend --save
npm install aurelia-configuration --save
Now add the following to the aurelia.json file in the dependencies array:
{
"name": "deep-extend",
"path": "../node_modules/deep-extend/lib/deep-extend"
},
{
"name": "aurelia-configuration",
"path": "../node_modules/aurelia-configuration/dist/amd",
"main": "index"
}
