BroccoliTypscriptCompiler error during ng serve

Running ng serve and making a change to a file gives me the following error:

This error does not occur when I kill the serve process and start it again.

I should add that this only appears when ng serve threw a TS compiler error anyway.

So when there's a TS error, and I fix it, I get the error mentioned above

@hansl

Also for me. @hansl is aware of that issue.

I am having the same issue except the error is still persisting after attempting to serve again

I'm getting the same behavior upon fixing a bug, except I get:

Error: Trying to add a new entry to an already existing one:

I have an open stackoverflow question with more details. Resetting the server does work for me.

A problem deleting old files like this prior ticket?

I upgraded to watchman as recommended under the ember-cli web site to see if this would fix the problem. Unfortunately, it did not.

So the problem happens with NodeWatcher and Watchman.

I also tried the emacs lockfile fixes as recommended under the ember-cli site, but no effect here either.

I am running Linux mint 17.3.

The problem is also reproducible for me under windows 10.

Since this problem was really bugging me -- to the point where I just couldn't work with angular-cli anymore, I just looked at the stack trace and basically zapped the code to ignore these problems. I've been using it for several hours now, and everything seems to work fine. I would think a real fix would be about figuring out why it's trying to use duplicate files, but here's what I did anyway:

edit module
node_modules/angular-cli/lib/broccoli/broccoli-typescript.js
edit method _addNewFileEntry like so (altered code marked by my initials 'vt'):

 _addNewFileEntry(entry) {
    const p = path.join(this.inputPaths[0], entry.relativePath);
    if (this._fileRegistry[p]) {
      //vt add
      console.log("vt.broccoli-typescript.js: intercepting dupicate entry error for" + p);
      //vt end
      //vtthrow new Error('Trying to add a new entry to an already existing one: ' + p);
    }

edit method _outputFile:

_outputFile(absoluteFilePath, fileContent, registry) {
absoluteFilePath = path.resolve(this.cachePath, absoluteFilePath);
// Replace the input path by the output.
absoluteFilePath = absoluteFilePath.replace(this.inputPaths[0], this.cachePath);
const outputFilePath = absoluteFilePath.replace(this.cachePath, this.outputPath);

if (registry) {
  registry.outputs.add(absoluteFilePath);
}

fse.mkdirsSync(path.dirname(absoluteFilePath));
const content = this.fixSourceMapSources(fileContent);
fs.writeFileSync(absoluteFilePath, content, FS_OPTS);

//vt add
try {
//vt end
  fse.mkdirsSync(path.dirname(outputFilePath));
  fs.linkSync(absoluteFilePath, outputFilePath);
//vt add
}
catch (e) {
  console.log('_outputFile: caught error ' + e);
}
//vt end
}

A full output log now looks like:

    file changed app/vtClass.ts

Note the Build Successful message at the end, instead of having to hit Ctrl-C and cycle the server. Once you get the condition, you always seem to get it e.g it seems to keep using the same tmp files over and over (?)

@vt5491

@vt5491 thanks for this, but IMO this is complex enough to let @hansl do the work. He rewrote the whole broccoli-typescript.js about a week ago and knows how things are in compiler. Since there's a really lousy docs about TS compiler or even not existent please wait, I think the patch is coming soon.

That's good news. Looking forward to the official patch.

This has been resolved with #416.

fixing the build by downgrading angular-cli to v0.0.30

+1 with cli beta.9 & angular2 rc.4

I had same weird problem with Angular-cli 1.0.0-beta.10 & Angular2 RC4

Does that happens when you delete some of the source file?

Check if this is repro in .11 version

I found my problem. (It was not same problem as in this topic. Sorry.)

When i add a parameter to constructor in my component (member.component.ts) i didn't update test file (member.component.spec.ts) manually. And i got error from tmp folder like below:

.../tmp/broccoli_type_script_compiler-input_base_path-gSIkus6k.tmp/0/src/app/mng/mng.component.spec.ts (10, 21): Supplied parameters do not match any signature of call target.

When i deleted/commented describe section in member.component.spec.ts, it was builded normally and error has gone.

So if you see an error about spec.ts and parameters, think about test file. Weird one is error does not tell about exact file.

I am using following versions

My app was working fine once I close the cmd and start again, I am getting below errors :

If you comment some code in the todos.component.spec.ts, this error will disappear.
Try to do it:

/* let component = new TestComponent();
expect(component).toBeTruthy() */

I know that I will need it for unit test, and I don't know how to solve it.
It's not a good solution.

Running into a similar issue with all spec files generated with angular-cli 1.0.0-beta.10 & Angular2 RC4 (or 5). For me 'ng serve' works fine, but 'ng build -prod' does not, and fails with:

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:
Error: Typescript found the following errors:
  S:/projects/fox1/ui/src/angular/web-application/tmp/broccoli_type_script_compiler-input_base_path-dQOJLOas.tmp/0/src/app/shared/component-outlet.directive.spec.ts (8, 21): Supplied parameters do not match any signature of call target.

In the code, the keywords describe, it and expect are all underlined with message "Cannot find name 'describe'" for example.

Renaming or removing the spec files fixes it, but it would be nice to be able to try out unit tests too. Any ideas would be appreciated. Thanks!

same problem on WINDOWS...RUN git bash as ADMINISTRATOR than problem solved

@victorazevedo

Great ! thanks @victorazevedo

"RUN git bash as ADMINISTRATOR than problem solved"
