Python 버전 및 패키지 설치 문제

을 실행하는 Linux 서버에 다른 Python 버전이 있습니다 Centos7.

[xyz@innolx20122]$ python
python             python2.7          python3.6          python3.7          python3.7m-config
python2            python3            python3.6m         python3.7m

python3.7 버전만 사용하고 싶어서 파일 .bashrc에 별칭을 만들었습니다 .

alias python=python3.7

Python 호출 모듈을 설치했으며 앞으로 계속 사용할 것입니다.

pip install invoke

기본 Python 2.7 위치에 설치됩니다.

[xyz@innolx20122 ~]$ pip install invoke
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: invoke in ./.local/lib/python2.7/site-packages (1.4.1)

버전 2.7이 **kwargs 매개변수를 지원하지 않기 때문에 호출 작업을 실행하는 데 문제가 있습니다. 이 문제를 어떻게 해결할 수 있나요?

고쳐 쓰다

다른 별칭을 만들었습니다.

pip=pip3.7

[xyz@innolx20122 ~]$ pip --version
pip 10.0.1 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

이제 pip install inform을 실행하면 이 문제가 발생합니다.

[xyz@innolx20122 ~]$ pip install invoke

나는 사용하려고

pip install invoke --user

그러면 해당 위치에 패키지가 설치되어 있는 것을 볼 수 있습니다.

[xyz@innolx20122 ~]$ pip 설치 호출 --user
