Reason cli global installation by yarn vs npm

[nimish-gupta]

Getting this weird error in reason vscode extension https://www.dropbox.com/s/okzqbp86jjcbj4c/Screenshot%202018-12-04%2022.58.30.png?dl=0

So I try reinstalling the reason-cli with yarn global add reason-cli@latest-macos. The error doesn't go, again I try installing using npm npm install -g reason-cli@latest-macos, extension starts working.

Is there any difference in installing reason-cli globally with npm vs yarn.

System Config ->
node- v8.6.0
npm- v5.3.0
yarn- v1.3.2
os- macOS High Sierra Version 10.13.6

Further both npm and yarn are installing the ocamlmerlin at the same location
