我正在嘗試使用 docker-compose 運行以下 Dockerfile。我四處搜索，但找不到有關如何使用 python:3.9-alpine 安裝 cffi 的解決方案。
我還閱讀了這篇文章，其中指出 pip 21.2.4 或更高版本可能是一個可能的解決方案，但它并沒有從我身上解決

缺少 libffi 庫。
將其添加到您的 dockerfile：
RUN apk add libffi-dev
uj5u.com熱心網友回復：
@Klaus D. 的評論很有幫助。我更新了 Dockerfile：
RUN apk add --update --no-cache --virtual .tmp-build-deps \
gcc libc-dev linux-headers postgresql-dev \
&& apk add libffi-dev
