Ubuntu源码安装python3.6.6

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
tar -zxvf Python-3.6.6.tgz -C [解压路径]
cd [解压路径]
./configure
make
sudo make install

如果安装失败,可能是由于缺少依赖
尝试
sudo apt-get install -y libbz2-dev libreadline-dev libsqlite3-dev libssl-dev build-essential zlib1g-dev make build-essential libreadline-dev llvm libncurses5-dev libncursesw5-dev openssl libpcre3 libpcre3-dev zip
再次sudo make install
查看默认是python和pip版本:

python -v
pip -v
which python
which pip

可以看到默认版本都不是python3.6.6
更改默认版本为python3.6.6

sudo rm /usr/bin/python
sudo ln -s /usr/local/bin/python3.6 /usr/bin/python

升级pip版本
pip install -U pip
