는 사실, 난 (os 및 sys 외에) 내가 사용하는 yaml, requests 및 json 수입 만 알고 : 맥 OS에 pip freeze를 사용하는 경우, 나는 모듈의 긴 목록을 가져옵니다.

명령이 나에게 내 프로젝트/파일

을 (하위 의존성 또는 시스템 라이브러리없이) 가져 오는 모듈의 첫 번째 단계가 나열하는 경우 ============= =

는

지금 virtualenv 및 pip freeze을 시도

UPDATE 보고서 :

certifi==2017.7.27.1 
chardet==3.0.4 
idna==2.6 
PyYAML==3.12 
requests==2.18.4 
urllib3==1.22

좋아요, 이것은 내 외장 수입품 (PyYAML과 requests)에 더 가깝습니다.

그리고 virtualenv 나는 단지 내 requirements.txt에 두 개의 모듈이 있어야합니다 것을 확인 :

(MYENV)$ python ./script.py 
... 
    import yaml 
ImportError: No module named yaml 

(MYENV)$ pip install PyYAML 
Collecting PyYAML 
Installing collected packages: PyYAML 
Successfully installed PyYAML-3.12 

(MYENV)$ python ./script.py 
... 
    import requests 
ImportError: No module named requests 

(MYENV)$ pip install requests 
Collecting requests 
    Using cached requests-2.18.4-py2.py3-none-any.whl 
Collecting urllib3<1.23,>=1.21.1 (from requests) 
    Using cached urllib3-1.22-py2.py3-none-any.whl 
Collecting idna<2.7,>=2.5 (from requests) 
    Using cached idna-2.6-py2.py3-none-any.whl 
Collecting chardet<3.1.0,>=3.0.2 (from requests) 
    Using cached chardet-3.0.4-py2.py3-none-any.whl

Successfully installed certifi-2017.7.27.1 chardet-3.0.4 idna-2.6 requests-2.18.4 urllib3-1.22 

(MYENV)$ python ./script.py 
It works!

다른 모든 요구 사항 (certifi, chardet, idna, urllib3가) 실제로 requests의 요구 사항입니다.

따라서 가져온 상위 종속성 만 가져 오는 방법 (수동 정리 제외)이 있습니까? 내 것 requirements.txt 예상 :
