该操作会创建 ENV/lib/pythonX.X/site-packages 目录 和 ENV/bin/python , 前者用来存放要安装的模块,后者就是隔离环境的Python解释器。 在virtualenv环境下使用此解释器(包括以 #!/path/to/ENV/bin/python 开头的脚本)时,使用的都是隔离环境下的模块。 (此外可更改setuptools、distribute的使用) S2、进入ENV,激...
1、创建一个项目,进入到这个项目的目录下,如项目目录为: "/Documents/PythonProject/AppDownload" cd /Documents/PythonProject/AppDownload 2、在这个目录下面创建python的独立运行环境,命名为venv,命令行如下: virtualenv --no-site-packages venv 命令virtualenv就可以创建一个独立的Python运行环境,我们还加上了参数-...
