Repro steps.

1. Run in terminal: ./node_modules/.bin/ng build --aot --env=dev --watch
2. -> The build is successful
3. Add a new line to any source file
4. The build will throw an error:

The log given by the failure.

Desired functionality.

Adding a new line shouldn't break the build

Hi Guys,

I also get this issue on change of source code like fixing an import reference.

I am using ng serve --aot

Regards,
Tarek

I reverted my typescript version to “<2.5.0” and it’s working fine.

[Brocco]

The current version of typescript supported is 2.4.2, please use that version for now. Support for later versions of TypeScript are being looked into.

[subatomicglue]

When using typescript 2.4.2 with ng build -prod, I get this error.
(Which the fix here says to upgrade typescript to 2.6.1.)

ERROR in ./node_modules/rxjs/_esm5/observable/BoundNodeCallbackObservable.js
Module build failed: TypeError: Cannot read property 'type' of undefined at Object.getEffectiveTypeAnnotationNode (node_modules/typescript/lib/typescript.js:9341:17).

When using typescript 2.6.1 with ng serve --aot, I get the above error when incrementally saving a .html or .ts file
(Which the fix above says to downgrade to typescript 2.4.2...)

ERROR in Error: Debug Failure. False expression: Host should not return a redirect source file from `getSourceFile`
    at tryReuseStructureFromOldProgram (.../node_modules/typescript/lib/typescript.js:72100:26)
    at Object.createProgram (.../node_modules/typescript/lib/typescript.js:71808:34)
    at AngularCompilerProgram._updateProgramWithTypeCheckStubs (.../node_modules/@angular/compiler-cli/src/transformers/program.js:461:30)
    at .../node_modules/@angular/compiler-cli/src/transformers/program.js:149:23
    at process._tickCallback (internal/process/next_tick.js:103:7)

So I am in a catch 22, where I need typescript 2.4.2 for ng serve --aot and typescript 2.6.1 for ng build --prod.

See also #8434. Typescript@next (currently 2.7.0-dev.20171216) is needed to fix other issues as well.

[DcsMarcRemolt]

The same error still shows up for current angular 5.2.x and @ngtools/webpack 1.10.1 if I use a TS version != 2.4.2. As Angular 5.2 officially supports TS 2.6 this is now a real bug, please reopen.

I'm having the same problem after moving an imported .ts file outside the app structure (it acts as a shared module). This works in the first build and fails after a live rebuild.

Using a non-aot developer build seems to work just fine. I can reproduce the issue every time, here's the log:

ERROR in Error: Debug Failure. False expression: Host should not return a redirect source file from `getSourceFile`

    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:118:7)

This is not critical, but a major nuisance. Any help?

[kspearrin]

Same problem here using Typescript 2.6.2, webpack 3.10, Angular 5.2.x with ngtools/webpack 1.10.2 (compiler-cli 5.2).

[denishvachhani]

Same problem here using Typescript 2.7.2, webpack 3.11.0, Angular 5.2.9

@Brocco I understand the issue was closed initially due to TypeScript version mismatch, but it seems like the issue can still be reproduced with 6.0.8, easily. Should this issue be reopened?
