ubuntu安装python-dev

ubuntu安装python-dev，首先需要的是换源，换成国内的源

cd /etc/apt/
cp sources.list source.list.bak
vim sources.list

修改为如下的源：

deb http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe
deb-class="lazy" data-src http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb-class="lazy" data-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb-class="lazy" data-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb-class="lazy" data-src http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb-class="lazy" data-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe

然后在安装过程中会出现依赖问题：

方法一：

使用aptitude解决问题：

• 1.安装 aptitude

sudo apt-get install aptitude 

• 2.然后用aptitude安装python-dev

sudo aptitude install python-dev 

然后在出现的选择中依次选择 n , y , y ，这样会自动解决依赖问题，可以升级或者降级需要的版本。

方法二：

使用pyenv，可以安装多版本的python

• 1.安装 pyenv

curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash  

• 2.安装完成后，根据提示将如下语句加入到 ~/.bashrc 中:

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"   # 这句可以不加

然后重启终端即可。
查看可安装的版本

$ pyenv install --list

安装对应的版本

$ pyenv install 2.7.5 -v

方法三

参考

echo "deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted" | sudo tee -a /etc/apt/sources.list.d/precise-updates.list  
sudo apt-get update  
sudo apt-get install python2.7-dev
sudo apt-get install python-dev
