【问题描述】：
我使用 pypy 基础的 Dockerfile 失败，并出现 FileNotFoundError: [Errno 2] No such file or directory: 'llvm-config' 安装 llvmlite 时，这是我的 requirements.txt 中列出的 numba 依赖项
我尝试遵循并更新此处的说明 Python numba / llvmlite on Debian 8 - i can't build llvmlite
我的错误更详细：
Building wheels for collected packages: llvmlite
Building wheel for llvmlite (setup.py): started

我不想要 conda 安装的重量。没有它有没有办法为 pypy 实现 numba 安装？

我希望在 pypy 上使用 numba 干净构建 docker 映像
【问题讨论】：
-
试试
FROM python:3.7-alpine3.9 RUN apk add --update alpine-sdk然后通过pip安装 -
我正在尝试使用 pypy3.6 而不是 python 3.7，已经成功使用 python3.7 docker 映像。也更喜欢使用 Debian stretch，因为 Alpine 没有我需要的许多库。
