Here are the steps that helped me yesterday to solve the problem:

Open package.json and remove the line where you define typescript dependency and its version
Remove node_modules folder
Remove package-lock.json file (if you use NPM 5+)
Run npm install typescript@latest --save
Run npm install

Hi, I had the same issue yesterday

Try to update your TypeScript dependency (should be ^2.4.0). npm i --save typescript

For me it completely solved the problem.

I can confirm that by generating a blank app using ng new testapp, adding ngx-datatables with npm install @swimlane/ngx-datatable@latest --save adding the import to app.module then you will get the reported error when you ng build you will get lots of In ambient enum declarations member initializer must be constant expression.

Running npm install typescript@latest --save-dev (note the use of --save-dev not --save) bumps the typescript version but there is a conflict with the version of typescript linked by @angular-cli@1.3.2 because typescript has now jumped to 2.5.2. Perhaps this isn’t an issue with the latest CLI.

±- @ angular/cli@ 1.3.2 | – typescript@ 2.4.2 – typescript@ 2.5.2

npm install typescript@2.4.2 --save-dev will avoid the conflict and ng build will compile as expected.

Upgrading from Angular 4.2.4 to 4.3.4: npm install @angular/core@4.3.4 @angular/animations@4.3.4 @angular/common@4.3.4 @angular/compiler@4.3.4 @angular/forms@4.3.4 @angular/http@4.3.4 @angular/platform-browser@4.3.4 @angular/platform-browser-dynamic@4.3.4 @angular/router@4.3.4 --save

npm install @angular/compiler-cli@4.3.4 @angular/language-service@4.3.4 --save-dev

and ng build still raises no errors.

I hope the above is helpful to someone.

@stas-kh Updading typescript dont fix error for me

But angular/compiler also complains if you use version greater (or equal to) than 2.5.0
