npm で [TypeError: Request path contains unescaped characters.] がでたときの対処

何の気なしにインストールしようとすると

# npm install -g coffee-script

npm http GET https://registry.npmjs.org/coffee-script

怒られた。

おもむろにプロトコルをhttpに変更する。。

# npm config set registry http://registry.npmjs.org/
# npm install -g coffee-script

npm http GET http://registry.npmjs.org/coffee-script
npm http 200 http://registry.npmjs.org/coffee-script
npm http GET http://registry.npmjs.org/coffee-script/-/coffee-script-1.6.3.tgz
npm http 200 http://registry.npmjs.org/coffee-script/-/coffee-script-1.6.3.tgz
/usr/local/bin/coffee -> /usr/local/lib/node_modules/coffee-script/bin/coffee
/usr/local/bin/cake -> /usr/local/lib/node_modules/coffee-script/bin/cake
coffee-script@1.6.3 /usr/local/lib/node_modules/coffee-script

# coffee -v
CoffeeScript version 1.6.3

めでたし。
