在我尝试安装 pip install -r requirements.txt 文件后，Docker 构建出现错误 [重复]

Question

这是我安装后遇到的错误

运行 pip install -r requirements.txt

RROR：服务“web”构建失败：命令“/bin/sh -c pip install -r requirements.txt”返回非零代码：1 ➜ django-docker pip 安装 psycopg2 默认为用户安装，因为普通站点包不可写 收集 psycopg2 使用缓存的 psycopg2-2.8.6.tar.gz (383 kB) 错误：命令出错，退出状态为 1： 命令：/usr/bin/python3.6 -c 'import sys，setuptools，tokenize； sys.argv[0] = '"'"'/tmp/pip-install-7xuxd9cm/psycopg2/setup.py'"'"'; 文件='"'"'/tmp/pip-install-7xuxd9cm/psycopg2/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'" ', open)(file);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"' "');f.close();exec(compile(code, file, '"'"'exec'"'"'))' egg_info --egg-base /tmp/pip- pip-egg-info-uon18vv4 cwd：/tmp/pip-install-7xuxd9cm/psycopg2/ 完整输出（23 行）： 运行 egg_info 创建/tmp/pip-pip-egg-info-uon18vv4/psycopg2.egg-info 写作/tmp/pip-pip-egg-info-uon18vv4/psycopg2.egg-info/PKG-INFO 将dependency_links写入/tmp/pip-pip-egg-info-uon18vv4/psycopg2.egg-info/dependency_links.txt 将顶级名称写入 /tmp/pip-pip-egg-info-uon18vv4/psycopg2.egg-info/top_level.txt 编写清单文件'/tmp/pip-pip-egg-info-uon18vv4/psycopg2.egg-info/SOURCES.txt'

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
<https://www.psycopg.org/docs/install.html>).

错误可能是由psycopy2-binary>==2.8 上的错误运算符引起的，根据pip docs 应该是>= 而不是>== 这可能会导致解析需求文件时出错。
