在 Ubuntu 13.10 Saucy 上安装 node.js 时
sudo add-apt-repository ppa:chris-lea/node.js -y
sudo apt-get update --fix-missing -y
sudo apt-get install nodejs npm nodejs-dev -y
我得到了这些
The following packages have unmet dependencies:
nodejs : Conflicts: nodejs-dev
Conflicts: npm
nodejs-dev : Depends: nodejs (= 0.10.15~dfsg1-4) but 0.10.22-1chl1~saucy1 is to be installed
E: Unable to correct problems, you have held broken packages.
我该如何解决这个问题?
