Decompression is moved to /usr/lcoal:
tar -zxvf Python-3.6.3.tgz
mv Python-3.6.3 /usr/local/
Installation dependency:
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
Delete old Python soft connection
rm -rf /usr/bin/python
Try to compile and install Python:
cd /usr/local/Python-3.6.3/
To configure:
./configure
Compile:
make
Installation:
make install
Failure to find suitable compiler:
configure: error: in /usr/local/Python-3.6.3': configure: error: no acceptable C compiler found in $PATH Seeconfig.log' for more details
Solve:
yum install gcc-c++
-bash: /usr/bin/yum: /usr/bin/python:bad interpreter no such file or dir
This is because the python soft connection is deleted, while Yum relies on python. So it would be nice to modify the yum file header and call Python to python2.7.
vim /usr/bin/yum File header invocation:
#!/usr/bin/python Change to ——> become /usr/bin/python2.7!
vim /usr/libexec/urlgrabber-ext-down
#! /usr/bin/python2 Change to ———> become /usr/bin/python2.7!
Re execution: installation compiler
yum install gcc-c++
Re execute compilation / installation:
cd /usr/local/Python-3.6.3/
To configure:
./configure
Compile:
make
Installation:
make install
Add Python soft connection again and connect to python3
cd /usr/bin
ln -s /usr/local/bin/python3 python
Execute Python -V to view Python version
python -V
Success
