Python 開發環境管理 virtualenvwrapper
阿新 • • 發佈:2019-02-15
virtualenvwrapper 時一個基於virtualenv之上的工具,它將所有的虛擬環境統一管理。
安裝
使用pip進行安裝
# whoami at iamwho in [~]
$ pip install virtualenvwrapper -i https://pypi.douban.com/simple/
初次啟動
- Ubuntu自帶python安裝的
virtualenvwrapper
source /usr/local/bin/virtualenvwrapper.sh
- miniconda或者anaconda安裝的
virtualenvwrapper
source miniconda2/bin/virtualenvwrapper.sh
還可以將該命令新增到~/.bashrc
或~/.profie
等shell啟動檔案中,以便登陸shell後可直接使用virtualenvwrapper提供的命令。
對於virtualenvwrapper的配置:
if [ `id -u` != '0' ]; then
export VIRTUALENV_USE_DISTRIBUTE=1 # <-- Always use pip/distribute
export WORKON_HOME=$HOME/.virtualenvs # <-- Where all virtualenvs will be stored
source /usr/local/bin/virtualenvwrapper.sh
export PIP_VIRTUALENV_BASE=$WORKON_HOME
export PIP_RESPECT_VIRTUALENV=true
fi
將上面的配置新增到 ~/.bashrc
的末尾或者~/.zshrc
虛擬環境
virtualenvwrapper預設將所有的虛擬環境放在~/.virtualenvs目錄下管理,
# whoami at iamwho in [~] $ source miniconda2/bin/virtualenvwrapper.sh virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/premkproject virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/postmkproject virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/initialize virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/premkvirtualenv virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/postmkvirtualenv virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/prermvirtualenv virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/postrmvirtualenv virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/predeactivate virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/postdeactivate virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/preactivate virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/postactivate virtualenvwrapper.user_scripts creating /home/whoami/.virtualenvs/get_env_details
可以修改環境變數WORKON_HOME來指定虛擬環境的儲存目錄。
常用命令
-
mkvirtualenv
usage:
mkvirtualenv [-a project_path] [-i package] [-r requirements_file] [virtualenv options] env_name
-
workon
workon env_name Deactivate any currently activated virtualenv and activate the named environment, triggering any hooks in the process. workon == lsvirtualenv Print a list of available environments. (See also lsvirtualenv -b) workon (-h|--help) Show this help message. workon (-c|--cd) envname After activating the environment, cd to the associated project directory if it is set. workon (-n|--no-cd) envname After activating the environment, do not cd to the associated project directory.
-
lsvirtualenv is equal to workon without params
-
deactivate 跟virtualenv的一樣
-
rmvirtualenv
$ rmvirtualenv --help Removing --help... Did not find environment /home/whoami/.virtualenvs/--help to remove.
以上為常用的命令足夠用,具體引數其實跟virtualenv差不多。
