Python virtual environment 만들기 (Cygwin)

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ python3 -m venv venv

venv라고 하는 virtual python 환경을 만들어 준다.

만약에 아래와 같은 오류가 나면

Error: Command '['/cygdrive/c/Users/home/Desktop/udacity_AWS/python/venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

cygwin에 virtual environment가 없기 대문이다.

이렇게 Package를 install 해서 virtualenv를 생성해도 될지 모르겠는데 난 잘 안되었다.

그래서

- pip3 install virtualenv

를 통해서 virtualenv를 설정 하였다.

아래 내용을 보면 virtualenv를 통해서 python이 virtual env로 setting 된것을 확인 가능하다

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ virtualenv env

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ ls
env

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ source ./env/bin/activate
(env)
home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ which python

(env)
home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ 

virtual env를 disalbe 시키고자 하는 방법은

deactivate를 사용하면 된다.

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ deactivate

virtualenv로 하니까 뭔가... 좀 잘 안되는 느낌이다.

그래서 apt-cyg를 install 하고

2021.05.11 - [잡동사니] - apt-cyg cygwin에 install

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ apt-cyg install python3-devel

devel를 설치 하고 나니까 상기에 썻던 문제 없이 잘 설치 된다.

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
$ python -m venv env

home@DESKTOP-H7MO8NQ /cygdrive/c/Users/home/Desktop/udacity_AWS/python
