我正在尝试使用“依赖关系扫描”设置Gitlab实例，但是我要分析的代码取决于psycopg2。
脚本片段如下：
- docker run
--env DEP_SCAN_DISABLE_REMOTE_CHECKS="${DEP_SCAN_DISABLE_REMOTE_CHECKS:-false}"
--volume "$PWD:/code"
--volume /var/run/docker.sock:/var/run/docker.sock
"registry.gitlab.com/gitlab-org/security-products/dependency-scanning:$SP_VERSION" /code/
我可以看到Gitlab如何提取图像，然后开始在我的requirements.txt中安装库，但是当它到达应该安装psycopg2的地步时，它失败了，因为它可以找不到pg_config。
$ export SP_VERSION=$(echo "$CI_SERVER_VERSION" | sed 's/^\([0-9]*\)\.\([0-9]*\).*/\1-\2-stable/')
$ docker run --env DEP_SCAN_DISABLE_REMOTE_CHECKS="${DEP_SCAN_DISABLE_REMOTE_CHECKS:-false}" --volume "$PWD:/code" --volume /var/run/docker.sock:/var/run/docker.sock "registry.gitlab.com/gitlab-org/security-products/dependency-scanning:$SP_VERSION" /code/

Error: pg_config executable not found.
pg_config is required to build psycopg2 from source. Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

问题很明显。它找不到二进制文件，该文件位于名为libpq-dev的程序包中。解决方案不是那么明显。我不知道如何在映像中安装该库。
有什么想法可以使依赖扫描程序安装libpq-dev吗？
