저는 파이썬을 처음 사용합니다. 최근에 파이썬으로 작성된 프로젝트가 있는데 설치가 필요합니다. 아래 명령을 실행하여 설치했지만 오류가 발생했습니다.
# 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
나는 Google에서 검색 하고이 링크를 찾았 http://stackoverflow.com/questions/28167987/python-pip-trouble-installing-from-requirements-txt
지만 그 게시물의 해결책을 이해하지 못합니다.
아래는 내 requirements.txt 파일입니다.
# 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
이 Python 프로젝트에 필요한 모든 종속성을 쉽게 설치할 수있는 방법이 있습니까?

아래는 pip3 install -r requirements.txt
.
# pip3 install -r requirements.txt
