Following is the answer from github
Fix for windows, I got this message :
npm update check failed Try running with sudo or get access to the
local update config store via sudo chown -R $USER:$(id -gn $USER)
C:\Users.configso I went on to C:\Users.config and deleted the
“configstore” folder. once I done this, next time a ran npm start, the
folder was re-generated, and error stopped
Fix for OSX:
After two hours of try-and-fail I managed to solve the issue as follows:
- go to folder /usr/local/lib/node_modules/
- right-click on the folder node_modules > go to Get Info
- update the permissions > add yourself and administrator account and set “read and write” for both
- run in the terminal “npm install packageName”
- if you still get the error, go to the same folder /usr/local/lib/node_modules/ and within the folder node_modules, update in the same way the permissions for the new package folder
- try to run again in the terminal “npm install packageName”
That worked for me! Hope it could help somebody.
