多个 Python 安装 - easy_install 和 pip 都失败

Question

我有 Python 3.3.3 的系统级安装，我想在 /usr/local/python33 的用户空间中进行安装，作为多版本 virtualenv 类型设置的一部分。我创建了目录，并尝试使用 easy_install 和 pip（作为系统级安装中的 easy_install-3.3 和 pip-3.3）将 Python 3.3.3 的副本放在那里。没有喜悦。两次尝试的日志如下所示。我认为这应该是直截了当的，但我的信心，如果标记。

您正在安装一个可能不安全且无法验证的文件。未来版本的 pip 将默认禁止不安全文件。

easy_install 和 pip 都用于安装 Python 包，而不是用于安装 Python 本身。

如何安装 Python 取决于您的操作系统。对于 Unices，您通常运行标准 configure; make; make install。
