Compiling v2.7.0 from npm causes a type error

[KonstantinEpam23]

Steps to Reproduce

1. Compile the app from npm v2.7.0-rc.4 (you may have to replace the package versions in example/package.json to point to the exact version)
   Example:

  "dependencies": {
    "ketcher-core": "2.7.0-rc.4",
    "ketcher-react": "2.7.0-rc.4",
    "ketcher-standalone": "2.7.0-rc.4",
...

2. Run yarn build

Actual behavior
A compilation error occurs:

#10 95.45 Failed to compile.

Expected behavior
No error should be present in console during compilation

Looks like the problem may be related to a bug in TypeScript that is reported here: microsoft/TypeScript#49466

Brief explanation of the problem:
This is likely because you have two, distinct copies of Ketcher class, relying on two distinct copies of the nominal Ketcher class (because of its private members) - one in ./packages/ketcher-core/dist (the one reachable via the types in the root import), and one in ./example/dist (the one reachable via the deep import). And we are essentially shipping two distinct packages worth of types.

Possible workarounds:

1. Add a // @ts-ignore comment above the line with the error, the project should build successfully
2. In App.tsx Editor component onInit event - change the type of Ketcher to Promise<Ketcher>
3. Use the following steps:

• remove yarn.lock from your project directory and any subdirectories that have package.json
• remove all "node_modules" directories from the project
• run yarn cache clean --all
• run yarn install then yarn build
• if you are working with the file structure, that is the same as in this repository - run yarn install and yarn build as well from the following directories: "example", "packages/ketcher-react", "packages/ketcher-core", "packages/ketcher-standalone"
