First, install python3

1. Install the dependency package yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc* make-y

2. Download the python installation package wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tar.xz

The reason for downloading and installing python3.5.2 here is mainly due to the good stability of combining Django in the later stage.

3. Extract the python installation package tar-Jxvf Python-3.5.2.tar.xz

4. Configure the installation path

Go to the decompression directory.

. / configure prefix=/usr/local/python3

5. Compile and install

Go to the decompression directory.

Make & & make install

6. Configure soft connection ln-s / usr/local/python3/bin/python3 / usr/bin/python3

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

Python3.5.2 and pip3 can now be used normally

It is found here that pip3 cannot be used after configuring soft links:

Solution:

[root@localhost bin] # which pip3/usr/bin/pip3 [root@localhost bin] # pip3-bash: / usr/local/bin/pip3: there is no such file or directory [root@localhost bin] # type pip3pip3 has been hashed (/ usr/local/bin/pip3) [root@localhost bin] # hash-r [root@localhost bin] # type pip3pip3 is / usr/bin/pip3

7. Export the list of packages previously installed by python in Windows

Open cmd and switch to Desktop

Pip freeze > package.txt

Then import it into Centos7 and install the module in the file with pip3

So far, the functions and common modules in python3 have been installed and can be used normally.

Uninstall python3

View the current python version:
