Illegal state: Could not load the summary for directive ObserveContent
See original GitHub issueBug, feature request, or proposal:
Bug
What is the expected behavior?
Angular Material and the CDK’s latest release/master is compatible with Angular 5.0.0-rc.7+ and Angular CLI 1.5.0-rc.5+.
What is the current behavior?
Build fails with the following error:
ERROR in Error: Illegal state: Could not load the summary for directive ObserveContent in /Users/splaktar/Git/tf/webapp/node_modules/@angular/cdk/observers/typings/index.d.ts.
What are the steps to reproduce?
Unable to reproduce in Stackblitz. Closest I came was https://stackblitz.com/edit/angular-material-with-angular-v5 which gives no errors.
I was unable to get @angular/flex-layout
to build since it requires a version from master or angular/flex-layout-builds
which isn’t accessible to Stackblitz (since not on NPM). I’m not having that problem in my local build.
What is the use-case or motivation for changing an existing behavior?
Dev and production builds passing.
Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular CLI: 1.5.0-rc.5
Node: 6.11.0
OS: darwin x64
Angular: 5.0.0-rc.7
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, platform-server, router

@angular/cli: 1.5.0-rc.5
@angular/flex-layout: 2.0.0-beta.9-99e7450
@angular/material: 2.0.0-beta.12-0ea4370
@angular-devkit/build-optimizer: 0.0.31
@angular-devkit/core: 0.0.20

@ngtools/webpack: 1.8.0-rc.5
@schematics/angular: 0.0.48
typescript: 2.4.2

I also tried with CDK and material2 on beta.12.
Is there anything else we should know?
No

OK, after numerous hours working on a reproduction and then changing code/config one at a time and rebuilding in AOT mode… I have finally solved this.
In my
tsconfig.app.json
file, I had the following:This had been here for 6+ months w/o any issues.
According to the TypeScript docs, this flag is for:
I have no idea if this was something that was part of the CLI at some point, or if it was some custom config added to fix a previous issue.
But just removing this single line of config, and my AOT build failures with the CDK are now solved!
In my case it did not help. I have
"rootDir": "src"
in my tsconfig and cannot simply remove this line.
