Typescript breaking Change on Keyv 5.3.3 - declarations of a private property '_ttl'.

[naanlizard]

NOTE: This is now fixed as we are deploying Keyv as a peer dependency. Please upgrade to the latest version of Keyvand supporting packages. An example would be using @keyv/redis:

npm update keyv @keyv/redis

For a fresh installation:

npm install --save keyv @keyv/redis

[deps 3/3] RUN yarn build:
0.399 yarn run v1.22.22
0.434 $ tsc

Works perfectly fine in 5.3.2, 5.3.3 breaks

This is because Keyv needs to be a peerDependency so we can release it at different types. New @keyv/redis will be published shortly.

@naanlizard - this is fixed now on @keyv/redis and published as v4.3.4

I'm still experiencing the same problem even after upgrading to the latest version:

"dependencies": {
...
  "@keyv/redis": "4.3.4",
  "keyv": "5.3.3",
...
}

TS2322: Type 'Keyv<any>[]' is not assignable to type 'Keyv<any> | KeyvStoreAdapter | (Keyv<any> | KeyvStoreAdapter)[]'.
  Type 'Keyv<any>[]' is not assignable to type '(Keyv<any> | KeyvStoreAdapter)[]'.
    Type 'Keyv<any>' is not assignable to type 'Keyv<any> | KeyvStoreAdapter'.
      Type 'import("/project/node_modules/keyv/dist/index").Keyv<any>' is not assignable to type 'import("/project/node_modules/keyv/dist/index").Keyv<any>'. Two different types with this name exist, but they are unrelated.
        Types have separate declarations of a private property '_ttl'.
