I am having trouble with npm and node version 0.10.40. I never had this problem before and I am not behind a proxy. I have tried other solutions that I found on Stack Overflow and other forums such as changing the registry url to http://.. rather than https://.., and setting strict-ssl to false. When I do this npm is unable to parse JSON. Here is my npm-debug.log. Maybe someone can help me figure out what is going on.
I solved this issue by issuing the following commands
npm config set proxy false npm cache clean
Apparently npm was attempting to bypass a proxy or believed it was behind a proxy. Strange.
