Trying to Install PouchDB with Ionic 4 goes wrong


I’m trying to migrate from ionic 2 to 4 beta.

I use PouchDB heavily.

I tried to install PouchDB to the project but it gets me errors right of the install code of PouchDB. Just type in the CMD: (Node 11.6)

npm install pouchdb --save

Gets me error like this:
The Platform for project ‘leveldb.vcxproj’ is in
valid. Platform=‘x64’. You may be seeing this message because you are trying t
o build a project without a solution file, and have specified a non-default Pla
tform that doesn’t exist for this project.

Any solutions?
