我有一个使用YAML的Python程序.我尝试使用它在新服务器上安装它pip install yaml,它返回以下内容:
$ sudo pip install yaml
Downloading/unpacking yaml
Could not find any downloads that satisfy the requirement yaml
No distributions at all found for yaml
Storing complete log in /home/pa/.pip/pip.log
如何安装Python的yaml包？我正在运行Python 2.7.(操作系统:Debian Wheezy)
