CentOS7 安裝 Python 3.6.1

在CentOS底下預設是Python 2.7版

以下是安裝Python 3.6.1版本方式

先安裝gcc

sudo yum install gcc

安裝openssl-devel [我碰到沒裝就會有"pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available"錯誤]

sudo yum install openssl-deve

下載Python 3.6.1

cd /usr/src
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
tar xzf Python-3.6.1.tgz

安裝Python 3.6.1 [要開啟shared 要不然安裝mod_wsgi 一直會錯誤，如果有問題就重新安裝一次Python]

cd Python-3.6.1
sudo ./configure --enable-shared --prefix=/usr/local
sudo make altinstall

測試Pyhton 3.6.1

python3.6 -v

測試pip

pip3.6

把pip3.6可以用sudo執行

sudo visudo
# 找到secure_path = /sbin:/bin:/usr/sbin:/usr/bin 這一行，後面加上 /user/local/bin
Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin/
