我是python的新手.最近我得到了一个由python编写的项目,它需要一些安装.我运行下面的命令安装但出错了.

# pip install requirements.txt 
Collecting requirements.txt
  Could not find a version that satisfies the requirement requirements.txt (from versions: )
No matching distribution found for requirements.txt

我在谷歌搜索并找到了这个链接,http://stackoverflow.com/questions/28167987/python-pip-trouble-installing-from-requirements-txt但我不太明白该帖子中的解决方案.

以下是我的requirements.txt文件:

# cat requirements.txt 
ordereddict==1.1
argparse==1.2.1
python-dateutil==2.2
matplotlib==1.3.1
nose==1.3.0
numpy==1.8.0
pymongo==3.3.0
psutil>=2.0

有没有一种简单的方法来安装这个python项目中所有必需的依赖项？

EDIT1

以下是输出pip3 install -r requirements.txt.

# pip3 install -r requirements.txt 
Requirement already satisfied: ordereddict==1.1 in /usr/local/lib/python3.5/dist-packages (from -r requirements.txt (line 1))
