python项目打包虚拟环境

python项目打包时，需要将虚拟环境与python自身安装路径下的lib包整合在一起，将如下内容保存为packvenv.sh文件，修改PYTHON\_PATH（python的安装路径）以及VENV\_PATH（虚拟环境的全路径）为自己的目录，然后给文件添加执行权限：chmod +x packvenv.sh，./packvenv.sh执行即可

Linux：packvenv.sh

#!/bin/bash
    
    PYTHON_PATH=/usr/local/python2.7
    VENV_PATH=~/.virtualenvs/venv-linux6
    
    VENV_NAME=`basename $VENV_PATH`
    
    echo $VENV_NAME
    
    mkdir $VENV_NAME
    mkdir $VENV_NAME/bin
    
    # copy python lib 
    cp -r $PYTHON_PATH/lib $VENV_NAME/lib
    rm -rf $VENV_NAME/lib/python2.7/site-packages
    
    # copy venv python
    cp $VENV_PATH/bin/python $VENV_NAME/bin/ || exit 1
    
    # copy venv lib
    packdir=$VENV_PATH/lib/python2.7
    for e in `ls $packdir`
    do
        files=$packdir/$e
        realfiles=`readlink $files`
        if [ $realfiles ]; then
            cp -r $realfiles $VENV_NAME/lib/python2.7/
        else
            cp -r $files $VENV_NAME/lib/python2.7/
        fi  
    done
    
    # remove .pyc .pyo and test files
    remove_pyc_and_pyo_files() {
        for e in `ls $1`
        do  
            fullpath=$1/$e
            if [[ "${e:0-5}" == "-info" || "${e:0-4}" == ".pyc" || "${e:0-4}" == ".pyo" || "$e" == "test" ]]; then
                echo delete file:$fullpath
                rm -rf $fullpath
            elif [ -d $fullpath ]; then
                remove_pyc_and_pyo_files $fullpath
            fi  
        done
    }
    
    remove_pyc_and_pyo_files $VENV_NAME/lib/python2.7
    
    rm -rf $VENV_NAME/lib/pkgconfig
    cd $VENV_NAME/lib
    ln -s python2.7 python
