腾讯云服务器配置(Ubuntu16.04)

1.首先备份apt更新源文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

然后更改源文件为清华大学开源软件镜像站

sudo vim /etc/apt/sources.list

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

2.升级python到python3.6.8

添加python3.6的仓库

sudo add-apt-repository ppa:jonathonf/python-3.6

更新源

sudo apt-get update

更新安装源后，输入如下命令安装Python3.6：

sudo apt-get install python3.6

安装完成之后，设置Python3.6的优先级，输入如下命令：

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

下一步，我们来更新pip，输入如下代码:

sudo apt-get install python3-pip
sudo pip3 install --upgrade pip

至此，python升级完成

输入pip -V

查看pip指向地址，是指向python3还是python2

3.修改PIP安装源

[global]
index-url = http://mirrors.aliyun.com/pypi/simple
trusted-host = mirrors.aliyun.com

4.安装虚拟环境

pip install virtualenv --user
pip install virtualenvwrapper --user

查看virtualenvwrapper.sh位置

which virtualenvwrapper.sh

编辑~/.bashrc文件

sudo vim ~/.bashrc

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/workspace
source /usr/local/bin/virtualenvwrapper.sh(更换为上面查到的位置)

然后执行

source ~/.bashrc

到这里，虚拟环境也已经安装好了

mkvirtualenv django_test -p python3
rmvirtualenv django_test
workon django_test

如果创建虚拟环境的时候出现/usr/bin/python: No module named virtualenvwrapper

那么就编辑~/.bashrc文件

export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
export PROJECT_HOME=$HOME/workspace
source /home/ubuntu/.local/bin/virtualenvwrapper.sh
