我有一个使用YAML的Python程序。我尝试使用pip install yaml在新服务器上安装它,它返回以下信息:
$ 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?我运行的是Python 2.7。(操作系统:Debian Wheezy)
