Question

我正在尝试使用pip将psycopg2安装到virtualenv中，但似乎有某种gcc错误，我无法理解。我已经按照其他一些问题的建议安装了python-dev和libpq-dev。

修改您的sources.list文件（通常位于etc/apt/sources.list中）并为每个对应的deb-src行添加deb。

deb http://in.archive.ubuntu.com/ubuntu/精确主要限制

deb-src http://in.archive.ubuntu.com/ubuntu/精确主要限制 #Add this line

deb http://in.archive.ubuntu.com/ubuntu/精确更新主要限制

deb-src http://in.archive.ubuntu.com/ubuntu/精确更新主要限制 #Add this line

两者之间的区别：

deb：这些存储库包含二进制文件或预编译包。大多数用户都需要这些存储库。
deb-src：这些存储库包含的源代码包。对开发人员有用。

现在尝试：

sudo apt-get update
sudo apt-get build-dep psycopg2  # The name has changed to `psycopg2` from `python-psycopg2`

Answer 2

您需要安装两件事：

sudo apt-get install build-essential
sudo apt-get build-dep python-psycopg2

第一个安装所需的构建工具，第二个安装在virtualenv中编译psycopg2所需的依赖项。

将psycopg2安装到virtualenv时出现gcc错误（Lubuntu 12.04，python 2.7）
