TypeScript error: Error TS1138: Parameter declaration expected.

[mpmysight]

I am getting the following error when I try to run my project.

TypeScript error: /home/user/projects/project/node_modules/ionic-native/node_modules/rxjs/Observable.d.ts(29,33): Error TS1138: Parameter declaration expected.

Thank you for the help in advance.

I am guessing you are using an older compiler version that what rxjs used to create this declaration file.

I should add that this bug report is really lacking in information. if this is a support request/question we recommend posting it on SO. This issue tracker is for TS compiler and language bugs/suggestions, and for these we ask you to fill in the issue template with version numbers, and self-contained sample repro of the issue in question. these bits of information allow us to diagnose the issue and respond accordingly.

have the same problem

[BenGWeeks]

Same issue? Any resolutions to this?

[mhegazy]

This issue is unactionable.

@CK110 and @webtechy please provide information about what version of the compiler you are using and a self-contained reproduction of the issue.

Ran the following:

git clone https://github.com/ministainer/Angular2SampleSPFx.git
npm i

Set ./config/write-manifests.json to:

https://[somecompany].sharepoint.com/sites/Development/SiteAssets/Angular2SampleSPFx/

Run the following:

gulp build

However, I received:

Error - typescript - node_modules\rxjs\Observable.d.ts(29,34): error TS1005: ')' expected.

Followed by a bunch of similar issues.

In the package I see:

"rxjs": "^5.0.0-beta.6",

So I tried running:

npm install rxjs --save
npm install typescript --save-dev

Unfortunately that did not resolve the issue.

tsd -v

[RyanCavanaugh]

tsc -v
Version 1.8.34

The .d.ts file you have uses this parameters, which are not supported in 1.8

constructor(subscribe?: (this: Observable<T>, subscriber: Subscriber<T>) => TeardownLogic);

You can upgrade tsc or get an older version of rxjs (looks like 5.0 doesn't use this but 5.1 does)

[BenGWeeks]

Thanks @RyanCavanaugh, although I though running:

npm uninstall typescript -g
npm cache clean
npm install typescript -g

Should upgrade me to the latest version, but running then running

tsc -v

Still gives version 1.8.34 - is the PATH environment variable throwing it off?

[RyanCavanaugh]

Run where tsc, see where the old version is being picked up from, modify your PATH appropriately

[BenGWeeks]

Removed the environment path, but not restarted machine yet, then ran:

C:\Projects\Angular2SampleSPFx>where tsc
C:\Users\b.weeks\AppData\Roaming\npm\tsc
C:\Users\b.weeks\AppData\Roaming\npm\tsc.cmd

[BenGWeeks]

OK, re-ran after removing the environment variable and success :-)

npm uninstall typescript -g
npm cache clean
npm install typescript -g

If I run tsc -v I now get 2.1.5 :-) This may explain some issues with some other projects I had too :-)
