我想我没有在Python 3中得到venv模块。
我有一个AWS EC2实例
yum
python
和
pip
是2.7,而
python3
命令是3.6.5。上市
pip freeze
默认情况下,2.7版安装了很多东西,但是运行
python3 -m pip freeze
显示3.6.5似乎没有安装。
我想通过使用python 3脚本为我的工作设置一个venv,可以更安全地安装一些模块。
使用
python3 -m venv ~/venv/aws
那时我可以
. venv/aws/bin/activate
python --version
仍然是2.7.14,但我认为安装
在激活的静脉里
python3 -m pip install --upgrade pip
. 这不起作用,因为首先它说它正在卸载PIP9.0.3,然后它转到并错误地链接:

用于

蟒蛇
也不是
那么激活有什么问题,我是不是应该以不同的方式创建这个?
