我正在尝试使用此命令在 django 中运行 dockerdocker build -t myimage .现在 docker 文件尝试运行,RUN pip install -r /app/requirements.txt --no-cache-dir但是当 ot 到达该Downloading psycopg2-2.9.3.tar.gz (380 kB)部分时,它会引发错误。
docker build -t myimage .
RUN pip install -r /app/requirements.txt --no-cache-dir

注意:我的 requirements.txt 文件中没有 psycopg2,只有psycopg2-binary.

如果要使用 psycopg2,则需要安装系统依赖项 (pg_*),否则,可以通过将 psycopg2 替换为 psycopg2-binary 来使用包含它们的一体化软件包
