Question

我刚刚完成了Linux Mint 17.3的全新安装。它配备了python 2.7和3.4。我通常使用python的多个版本，所以我只是做一个altinstall然后为每个项目我使用所需的python版本创建virtualenv。但是我遇到了新安装的操作系统的问题。首先介绍安装后我已经完成的一些事情：

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install python-virtualenv
sudo apt-get install python-pip

我做了一个python3.3.5：

downloaded the source tarball
./configure --with-zlib
sudo make
sudo make altinstall

然后我尝试在新文件夹中创建virtualenv进行测试：

virtualenv -p python3.3 venv

这给出了一个错误：

no module named zlib

我以前遇到过这个问题，所以我做了：

sudo apt-get install python-dev
sudo apt-get install zlib1g-dev

现在，当我创建virtualenv时，zlib错误消失了，但是我得到一个新的错误，我似乎无法弄清楚如何解决它：

Running virtualenv with interpreter /usr/local/bin/python3.3

我在某处读到这可能与openssl有关，所以我做了：

sudo apt-get install openssl
sudo apt-get install libcurl4-openssl-dev

没有运气，仍然有同样的问题。

我让其他人做这项工作，所以我不必担心自己从源头构建替代版本。

我使用Felix Krull＆＃34; deadsnakes＆＃34;真的好运。 PPA用于在Ubuntu上安装备用Pythons。这适用于Mint 17吗？（基于Ubuntu Trusty）

＆＃39; deadsnakes PPA＆＃39;软件包的版本：2.3,2.4,2.5,2.6,2.7,3.1,3.2,3.3,3.4,3.5 ......所有这些都可以从apt安装。安装完成后，您可以使用virtualenv和pip来管理版本和依赖项。

从deadsnakes安装Python 3.5 PPA：

$ sudo add-apt-repository ppa:fkrull/deadsnakes
$ sudo apt-get update
$ sudo apt-get install python3.5 python3.5-dev

PPA维护者已经维护了很长时间并且每次更新Ubuntu都会更新。
