我正在尝试使用以下 dockerfile 为 alpine3.7 python base 安装密码学。 但是,我收到这样的错误:

根据 cryptography 文档,我正在安装所有必要的软件包,但仍然出现相同的错误。 Dockerfile:
FROM python:3.7-alpine
WORKDIR /project
RUN apk add --no-cache --virtual gcc musl-dev python3-dev libffi-dev openssl-dev cargo mariadb-dev
RUN pip install pymysql cryptography
谁能指出我做错了什么?
答案 0 :(得分:0)
-t, --virtual NAME 不是将所有包添加到 'world' 中,而是创建一个新的 具有列出的依赖项的虚拟包并添加它 到“世界”;命令的动作很容易恢复 通过删除虚拟包
<块引用>这意味着当您安装软件包时,这些软件包不会添加到全局软件包中。而且这种变化很容易恢复。所以如果我需要gcc来编译一个程序,但是一旦程序被编译,我就不再需要gcc了。
<块引用>我可以在一个虚拟包中安装 gcc 和其他所需的包,它的所有依赖项和一切都可以从这个虚拟包名称中删除。下面是一个示例用法:
<块引用>this.add.text(100, 600, 'Test Text', {
font: '600 50px Poppins' // 600 equivalent to Semi Bold
})
因此,对您而言,在 apk add --virtual .dep gcc
apk del .dep
中,apk add --no-cache --virtual gcc
被错误地视为虚拟包名称,这意味着您实际上没有安装 gcc。
要解决此问题,请尝试在所有包之前添加一个虚拟包名称作为下一个:
gcc
或者直接如文档所说,去掉/ # apk add --no-cache --virtual .dep gcc
