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

pip install psycopg2

编辑您的 sources.list 文件（通常在 中找到）并为每个相应的行etc/apt/sources.list添加一个。deb-srcdeb

deb http://in.archive.ubuntu.com/ubuntu/精确主要受限

deb-src http://in.archive.ubuntu.com/ubuntu/精确主受限#添加这一行

deb http://in.archive.ubuntu.com/ubuntu/precision-updates主要受限

deb-src http://in.archive.ubuntu.com/ubuntu/precision-updates main restricted #添加这一行

两者的区别：

  • 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：这些存储库包含软件包的源代码。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`

You need to install two things:

  1. sudo apt-get install build-essential
  2. sudo apt-get build-dep python-psycopg2

The first installs the necessary build tools you need, and the second installs the dependencies you need to compile psycopg2 inside a virtualenv.
