npm install grunt failing on underscore.string dependency

[bprosnitz]

npm install grunt
....
npm ERR! Error: No compatible version found: underscore.string@'~2.2.0rc'
npm ERR! Valid install targets:
npm ERR! ["0.9.2","1.0.0","1.1.3","1.1.4","1.1.5","1.1.6","2.0.0","2.1.0","2.1.1","2.3.0","2.3.1","2.3.2","2.2.1","2.2.0-rc","2.3.3"]
...

If you look at Grunt's packages.json,
"underscore.string": "~2.2.0rc",

According to the underscore.string changelog, 2.2.1 is the same as 2.2.0rc to resolve this npm issue.

Could you try npm cache clean and then try installing again?

[bprosnitz]

Yes, I still see the issue after running npm cache clean.

Here is a related issue: #886. Which version of npm are you running? npm -v

I have 1.2.18. I will close this issue because it appears to be a duplicate.
