Today, the editor will share with you the relevant knowledge about how to install the python3 environment under linux. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

1. Install python3 under linux

Prepare to compile the environment (if the environment is wrong, you may encounter all kinds of problems, such as wget cannot download the files linked by https)

Yum groupinstall 'development tools'yum install zlib-devel bzip2-devel openssl-devel ncurses-devel

2 download the python3.5 code package

Wget https://www.python.org/ftp/python/3.5.0/python-3.5.0.tar.xz

In the installation package, there is a readme file that writes how to install

Tar jxvf python-3.5.0.tar.xzcd python-3.5.0./configure-- prefix=/usr/local/python3make & & make install

Make a soft chain:

Ln-s / usr/local/python3/bin/python3.5 / usr/local/bin/python3

The installation was successful!

If prompted: ignoring ensurepip failure: pip 7.1.2 requires ssl/tls

This is why oenssl is not installed or upgraded:

Yum install openssl-devel

Repeat the compilation scheme python3.5 again:

The final result is as follows:

Prompt to install both pip-7.12 and setuptools successfully!

Both pip3 and pip indicate that there are no errors!

Make a soft chain:

Ln-s / usr/local/python3/bin/pip3.5 / usr/local/bin/pip

Upgrade pip to the latest version:

Pip install-upgrade pip

Pip installed successfully!

Note:-- no-check-certificate means "do not check the certificate" during installation, without adding that it may not be able to install.

two。 Installation package

Requests package:

Pip install requests

Pyquery package:

Pip install pyquery

Pymysql package:
