Python3安装与配置venv虚拟环境

1、安装python3并设置为默认使用

用brew安装Python3，默认安装的目录是：/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/

配置默认使用python：

2、安装venv

pip install venv报错：

ERROR: Could not find a version that satisfies the requirement venv (from versions: none)
ERROR: No matching distribution found for venv

安装失败：zipimport.ZipImportError: can't decompress data; zlib not availabl

需要先安装依赖：brew install zlib

改为安装virtualenv

3、pycharm中选定虚拟环境后运行程序报错

12:56 下午    Error running 'runner': Cannot run program "/Users/kouyuru/.pyenv/versions/vlrp/bin/python" (in directory "/Users/kouyuru/Documents/voice_h2/lrp"): error=2, No such file or directory

需要使用命令 virtualenv venv1 新建一个虚拟环境,进入该虚拟环境需要使用激活命令 source venv1/bin/activate.

退出虚拟环境：deactivate

然后可以在虚拟环境中安装包
