I hope you can get something after reading this article. Let's take a look at this "what is the method of installing python3 in Linux system".

1. Install the dependency package 1. Install the gcc compiler first. Some system versions of gcc have been installed by default. Check through gcc-version. Install gcc,yum-y install gcc first if not installed.

2. Install other dependent packages. (note: do not lack it, otherwise there may be errors in installing python. Versions below python3.7.0 may not install libffi-devel.)

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 libffi-devel

Second, download the python3.7.0 source code. 1. Select the python source code package you need in https://www.python.org/ftp/python/. I downloaded python3.7.0 (you can also download it from the home page of the https://www.python.org official website, find downloads, and you can choose the version you want to download).

2. Download

Wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

3. Decompress Python-3.7.0.tgz

Tar-zxvf Python-3.7.0.tgz

4. Create an empty folder for storing python3 programs

Mkdir / usr/local/python3

5. Execute configuration file, compile, compile and install

Cd Python-3.7.0. / configure-- prefix=/usr/local/python3 make & & make install installation completed without error and installed successfully

6. Establish a soft connection

Ln-s / usr/local/python3/bin/python3.7 / usr/bin/python3 ln-s / usr/local/python3/bin/pip3.7 / usr/bin/pip37, test whether python3 can be used

[root@mini Python-3.7.0] # python3 Python 3.7.0 (default, Jul 28 2018, 22:47:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux Type "help", "copyright", "credits" or "license" for more information. > print ("hello world!")
