Can't resolve all parameters for TranslateServ

问题:

I could not test my ionic 3 app in browser anymore since yesterday because I get the following error related to TranslateService. This seems not related to my code since I also face the same issue when I switch to my previous versions, although it worked fine at that moment. I tried to re-install the node modules with but still no luck. Do you know what I should do to solve this problem? Thanks!

ERROR Error: Uncaught (in promise): Error: Can't resolve all parameters for TranslateService: (?, ?, ?, ?, ?, [object Object], [object Object]).

回答1:

Today we faced the same problem in one of our workstation that shares the same node_module folder with the others! The error seems to be related with the latest Chrome updated version or the generated ts Source Maps or both, because when we were running our apps in dev mode to other browsers were working fine... A quick fix is to do a production build and load it on Chrome , then try again in dev mode. At least this worked for us and maybe will work for others to.

回答2:

+1 to the issue. Sorry for posting as an answer - got no enough points to comment)

"@ngx-translate/core": "9.1.1",
"@ngx-translate/http-loader": "2.0.1",

It worked perfectly yesterday, and nothing was changed or upgraded since then. I am using angular-cli in dev mode, and what is interesting is that there is no such error if serving with --prod for production. Hope it will help somehow to figure this out!

I also have the same version @ngx-translate/core": "^9.1.1" and @ngx-translate/http-loader": "^2.0.1"
