This article mainly introduces the relevant knowledge of centos7 how to deploy python3 virtual environment, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this centos7 article on how to deploy python3 virtual environment. Let's take a look at it.

1. Install development tools

Yum-y groupinstall "Development tools"

2. Install the Python dependent library

Yum-y install

Zlib-devel

Bzip2-devel

Openssl-devel

Ncurses-devel

Sqlite-devel

Readline-devel

Tk-devel

Gdbm-devel

Db4-devel

Libpcap-devel

Xz-devel

Ibffi-devel (3.7New)

3. Install Python

Use wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz

After downloading, extract and install to / usr/local/python3

Mv Python-3.7.3.tar.xz / usr/local/python3

Tar-xJf Python-3.7.3.tar.xz

Cd Python-3.7.3

. / configure-prefix=/usr/local/python3-with-ssl

Make

Make install

Note:-- with-ssl needs to be added to the configure here. If you don't add it, an error will be reported when using pip3:

Pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

During the. / configure process, if the-with-ssl parameter is not added, the default installed software involves that the ssl function is not available

It just so happens that the pip3 process requires a ssl module, which is not available because it is not specified.

4. Establish a soft link after the installation is completed

Ln-s / usr/local/python3/bin/python3 / usr/bin/python3

Ln-s / usr/local/python3/bin/pip3 / usr/bin/pip3

Because the newly installed Python3 program is python3, which does not conflict with the python2:/usr/bin/python used by the original yum, the two can coexist.

5. Create a virtual environment for python3

Download virtualenv and install

Pip3 install virtulenv

Create a virtual environment (named qingyeyun)

Virtulenv blog-p / usr/bin/python3

Enter the virtual environment

Cd / usr/local/python3/blog

Source. / bin/activate

Exit the virtual environment

(qingyeyun) $deactivate
