First i thought that this may be proxy issue So I've added my corporate proxy settings:

yarn config set proxy http://proxy.dvfu.ru:3128
yarn config set https-proxy https://proxy.dvfu.ru:3128

But nothing happened, still have the error above.

Try below this three commands. Its worked for me.

  1. yarn config delete proxy
  2. npm config rm proxy
  3. npm config rm https-proxy
