Question

我尝试在终端上使用以下命令安装numdifftools（ubuntu 12.04）：

sudo pip install numdifftools

并默认为python3.2安装它。有没有办法强制它安装版本2.7的包

sudo python2.7 get-pip.py

Answer 1

也为python 2.7安装pip;

Download get-pip.py。
运行python2.7 get-pip.py。

或者通过您选择的包管理器安装它。

然后使用pip2.7为Python 2.7安装内容。

python2.7上的numdifftools vs 3.2
