嘗試 dockerize Django 應用程序，Docker 找不到 ft2build.h

Question

我是 Docker 的新手，我正在嘗試對 Django 應用程序進行 docker 化，但是當我運行docker build -t sometag. 我收到以下錯誤：

我不確定它是否與 ft2build.h 有關。我是不是在我的 dockerfile 上遺漏了什么？

注意：我不得不刪除 dockerfile，因為 Stackoverflow 不允許我發布這么多代碼，但我正在運行這個RUN apk update \&& apk add --no-cache gcc musl-dev postgresql-dev python3-dev libffi-dev \&& pip install --upgrade pip

解決ft2build.h的錯誤問題。 在編譯過程中，需要安裝freetype庫

我假設您使用的是最新版本的 Alpine，我可以看到您可以毫無問題地安裝 pip 個軟件包。

因此，缺少的部分應該是要安裝的 freetype-dev package。

RUN apk update \ 
 && apk add --no-cache gcc musl-dev postgresql-dev python3-dev libffi-dev freetype-dev\
