doesn't work dev-server

[dimorin]

When I did 'npm run dev-server', I got message 'Failed to compile'.
What should I do? Could you advise for me?

Error is below :

ERROR in ./client/index.tsx

With node 12.20.1 I have the same issue, but with node 10.* I have a different issue

ERROR in ~/csslayout/client/patterns/sticky-table-column/Details.tsx(95,73)

Fixed in the #163.
