如何在似乎没有 gcc 访问权限的 virtualenv 中安装 psycopg2？

Question

我正在尝试在 virtualenv 中安装 psycopg2，但似乎我无权访问 gcc。

有没有办法从 virtualenv 内部激活 gcc？如果没有，是否还有其他与 PostgreSQL 兼容但不使用 gcc 的库？

我尝试在 A2hosting.com 安装 psycopg2 时出现以下错误：

更新：

我发现我尝试安装 psycopg2 的计算机没有 PostgreSQL。网络托管公司在另一台服务器上安装了 PostgreSQL。在这种情况下可以做什么呢？

Answer 1

您不需要 PostgreSQL，您需要 PostgreSQL 客户端库和开发文件。您可以尝试要求主机安装它们，或者如果失败，您可以在类似的平台上构建它并手动复制软件包。
