Create a virtual environment on the server centos7 of Django's personal blog website, djangocentos7
1. Install virtualenv

Installation Method

Pip install virtualenv # install pip3 install virtualenv # install it in python2

2. Install virtualenvwrapper

Installation Method

Pip install virtualenvwrapper # install it in python2 pip3 install virtualenvwrapper # install it in python3

Note that both of them must be installed. If only python3 is installed, the workon command cannot be used.

Set

Locate

find / -name virtualenvwrapper.sh

We will find two locations.

/Usr/local/python3/bin/virtualenvwrapper. sh #/usr/bin/virtualenvwrapper. sh # In python3

Later we will use the location in python3.

Edit configuration file

cdvim ~/.bashrc

Add the following two commands to the end and specify the location of the virtual environment.

export WORKON_HOME=~/.virtualenvssource /usr/local/python3/bin/virtualenvwrapper.sh

Execute. bashrc to make the file take effect

source ~/.bashrc

Create a virtual environment

mkvirtualenv -p /usr/bin/python3 blog_env_py3

In this way, the virtual environment blog_env_py3 is created.

You can run the workon command to view the directories of all virtual environments and enter the virtual environment.

workon blog_env_py3

3. Install the dependency package in the virtual environment

Go to blog_test in windows and run the following command to export all packages to be installed:

pip freeze > requirements.txt

Use winscpsoftware to import the generated requirements.txt to linux.

Go to the virtual environment blog_env_py3 in linux and run the following command to install all the packages.

pip install -r requirements.txt

When mysqlclient = 1.3.12 is installed, an error is reported. You need to install another dependency package.

yum install mysql-devel

Check the installed package through pip list.
