I got an error of

node_modules/rxjs/internal/types.d.ts(81,44): error TS1005: ';' expected.

after the installation of Angular 6.

Check the error:

This problem might arise due to version mismatch. To solve your problem you need to do following changes in your package.json file.

Step 1 : Go to package.json and modify "rxjs": "^6.0.0" to "rxjs": "6.0.0"

Step 2 Run npm update in your project.

There is no need to change the typescript version. (Mine: "typescript": "~2.7.2")

Edit: If you are using rxjs-compat then you also need to do following in order to fixed the issue. change the rxjs-compat version from "rxjs-compat": "^6.2.2" to "rxjs-compat": "6.2.2"

Hope this will help!

I had the same error using angular 6 having rxjs@6.4.0 but i downgraded it to rxjs@6.3.3 it worked.

You need to do some changes in package.json

Go to package.json and modify "rxjs": "^6.0.0" to "rxjs": "6.0.0"

Then run npm update in your project

回答4:

If you are using rxjs-compat then you also need to do following in order to fixed the issue. change the rxjs-compat version from

"rxjs-compat": "^6.2.2"

"rxjs-compat": "6.2.2"

This works for me

回答5:

Go to the project directory run this command

npm install rxjs@6.0.0 --save

Earlier, I used to fix the problem with @TheParam's answer but lately started using yarn. Sadly I could not find yarn equivalent of

nmp update

I tried using

yarn upgrade

(although it is not equivalent of above command afaik) and it did not help.

I instead used

yarn add rxjs@6.0.0

and it worked. It took considerable time 82 sec as compared to few seconds in case of npm but fixed the issue. my node 8.11.2 and yarn 1.15.2

I just needed to edit the file and add the semicolon at the final line after 0 as shown here:

Go to the path [project directory]/node_modules/rxjs/internal and open the file types.d.ts as administrator, move to the final of the file and add a semicolon.

Original code: export declare type ObservedValueOf<O> = O extends ObservableInput<infer T> ? T : never;

Modified code: export declare type ObservedValueOf<O> = O; extends ObservableInput<infer T> ? T : never;

回答8:

Just do this, This work for me and hopefully work for you as well.

npm install rxjs@6.0.0 --save

回答9:

if you are still facing the problem, go to package.json

remove rxjs and add rxjs-compat also, "rxjs-compat": "^6.4.0" to "rxjs-compat": "6.4.0",
change the typscript version to 2.8
run npm install

This will work for you!

I had the same issue, the "rxjs": "^6.0.0" to "rxjs": "6.0.0" didn't work. I had to update my angular CLI to last stable npm install -g @angular/cli and regenerate the project again.

My config now is :

Angular CLI: 7.3.6
Node: 10.15.3
OS: win32 x64
Angular: 7.2.9

回答11:

I had same problem

npm install typescript@2.8.0

solved my problem

回答12:

This issue is caused by version of typescript installed was not compatible with that of the rxjs installed.Installation of typescript as mentioned below helped me install the compatible version of typescript with that of the angular packages already installed.You can resolve the issue by the below command
