Ubuntu18.04从源代码安装Python3.9

Posted by lili on February 2, 2024

本文解释在Ubuntu18.04下从源代码build安装Python3.9的方法。

目录

Ubuntu18.04通过apt能够安装最新的python版本是3.8，但是我们有的时候需要更高版本的python，比如3.9。一种方法是通过conda安装，但是有的时候我们没有安装conda，那么我们可以通过源代码编译安装python(我们这里当然说的是cpython)。

sudo apt-get update
sudo apt-get install gdebi-core

sudo apt-get install \
    curl \
    gcc \
    libbz2-dev \
    libev-dev \
    libffi-dev \
    libgdbm-dev \
    liblzma-dev \
    libncurses-dev \
    libreadline-dev \
    libsqlite3-dev \
    libssl-dev \
    make \
    tk-dev \
    wget \
    zlib1g-dev

还需要安装uuid-dev libgdbm-compat-dev，否则会出现：

sudo apt-get install uuid-dev libgdbm-compat-dev

The necessary bits to build these optional modules were not found:
_dbm                  _uuid

export PYTHON_VERSION=3.9.18
export PYTHON_MAJOR=3
curl -O https://www.python.org/ftp/python/${PYTHON_VERSION}/Python-${PYTHON_VERSION}.tgz
tar -xvzf Python-${PYTHON_VERSION}.tgz
cd Python-${PYTHON_VERSION}

build

./configure --enable-optimizations 
make
sudo make install
