npm "error network getaddrinfo ENOTFOUND"

I am trying to install different modules through npm. ``` c:\>npm install -g express ``` But I am getting following error message: ``` 0 info it worked if it ends with ok 1 verbose cli [ 'D:\\FH Kiel\\WS 13\\Advanced Javascript\\nodejs\\\\node.exe', 1 verbose cli 'D:\\FH Kiel\\WS 13\\Advanced Javascript\\nodejs\\node_modules\\npm\\bin\\npm-cli.js', 1 verbose cli 'install', 1 verbose cli 'express' ] 2 info using npm@1.3.14 3 info using node@v0.10.22 4 verbose node symlink D:\FH Kiel\WS 13\Advanced Javascript\nodejs\\node.exe 5 verbose cache add [ 'express', null ] 6 verbose cache add name=undefined spec="express" args=["express",null] 7 verbose parsed url { protocol: null, 7 verbose parsed url slashes: null, 7 verbose parsed url auth: null, 7 verbose parsed url host: null, 7 verbose parsed url port: null, 7 verbose parsed url hostname: null, 7 verbose parsed url hash: null, 7 verbose parsed url search: null, 7 verbose parsed url query: null, 7 verbose parsed url pathname: 'express', 7 verbose parsed url path: 'express', 7 verbose parsed url href: 'express' } 8 silly lockFile f3c62de4-express express 9 verbose lock express C:\Users\MW\AppData\Roaming\npm-cache\f3c62de4-express.lock 10 silly lockFile f3c62de4-express express 11 silly lockFile f3c62de4-express express 12 verbose addNamed [ 'express', '' ] 13 verbose addNamed [ null, '*' ] 14 silly lockFile 64a534c1-express express@ 15 verbose lock express@ C:\Users\MW\AppData\Roaming\npm-cache\64a534c1-express.lock 16 silly addNameRange { name: 'express', range: '*', hasData: false } 17 verbose url raw express 18 verbose url resolving [ 'http://registry.npmjs.org/', './express' ] 19 verbose url resolved http://registry.npmjs.org/express 20 info trying registry request attempt 1 at 15:47:46 21 http GET http://registry.npmjs.org/express 22 info retry will retry, error on last attempt: Error: getaddrinfo ENOTFOUND 23 info trying registry request attempt 2 at 15:47:59 24 http GET http://registry.npmjs.org/express 25 info retry will retry, error on last attempt: Error: getaddrinfo ENOTFOUND 26 info trying registry request attempt 3 at 15:49:01 27 http GET http://registry.npmjs.org/express 28 silly lockFile 64a534c1-express express@ 29 silly lockFile 64a534c1-express express@ 30 error network getaddrinfo ENOTFOUND 30 error network This is most likely not a problem with npm itself 30 error network and is related to network connectivity. 30 error network In most cases you are behind a proxy or have bad network settings. 30 error network 30 error network If you are behind a proxy, please make sure that the 30 error network 'proxy' config is set properly.

There is no proxy setting so this should work (and is working in other computers)... I have installed node.js without any problem. Thanx. Update: Here is the windows host file : ``` # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 localhost 127.0.0.1 localhost 127.0.0.1 localhost ``` I have also tried this solution found in other post: ``` npm install <packagename> --registry http://registry.npmjs.org/ ``` Didn't work either :(
