python - 密码坏了

Question

这个周末我们的 docker 镜像坏了，因为它不能再构建了。在查看统计数据时，我看到了这一行:

crypt_blowfish-1.2/crypt.h:17:23: fatal error: gnu-crypt.h: No such file or directory

更详细:

  Failed building wheel for cryptacular
  Running setup.py clean for cryptacular

我们的实现使用包 cryptacular使用 bcrypt .上周没有更新任何软件包，我不知道从哪里开始。

作为附加信息，错误发生在我们的 Dockerfile

的这个 block 中

RUN apt-get install -y build-essential libfontconfig && \
    pip install -q -U pip && \
    pip install -q -r requirements.txt && \
    apt-get remove -y --purge build-essential && \
    apt-get autoremove -y && \
    apt-get clean -y

requirements.txt 使用 cryptacular==1.4.1

编辑:我们正在使用 python:3.6-slim 图像

Answer 1

我在运行 python 3.6.6 时遇到了同样的问题。有了这个衬垫，我就能够从最新的提交中安装 cryptacular。

pipenv install -e hg+https://bitbucket.org/dholth/cryptacular@cb96fb3#egg=cryptacular

你需要安装 mercurial

apt-get update && apt-get install -y mercurial
