导读：我有一个Raspbery Pi,我通过执行以下操作升级到 Python 3.3.3： sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-devwget http://www.python.org/ftp/python/3.3.3/Python-3.3.3.tar.bz2tar jxf ./Python-3.3.3.tar.bz2cd ./Pyth

我有一个Raspbery Pi,我通过执行以下操作升级到 Python 3.3.3：

sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev
wget http://www.python.org/ftp/python/3.3.3/Python-3.3.3.tar.bz2
tar jxf ./Python-3.3.3.tar.bz2
cd ./Python-3.3.3
./configure --prefix=/opt/python3.3.3
make && sudo make install

但是在执行之后：virtualenv -p /opt/python3.3.3/bin/python3.3 python3.3.3

我收到此错误消息：

解决方法

当像Giorgio提到的那样构建2.7时,我也遇到了这个问题. user3301335是完全正确的 – 在构建python时,有可编译的可选模块具有库依赖性.

为了节省人们挖掘注释的时间,解决方案是在您的操作系统上安装SSL开发包. APT包叫做libssl-dev;在Red Hat上,它看起来像openssl-devel.
