无法在Docker容器上安装fasttext

Question

我正在尝试构建一个Python Docker容器。

这是我的Dockerfile：

# syntax=docker/dockerfile:1
FROM python:3.8-slim
WORKDIR /src
COPY req.ini req.ini
RUN apt-get update
RUN pip install --upgrade pip setuptools wheel
RUN pip install -r req.ini
COPY . .
CMD ["python3","flask","run","--host=0.0.0.0"]

我的req.ini文件看起来像这样：

Flask fasttext gensim nltk scipy pandas numpy

但是当我运行docker build --tag python-app时，我会收到以下错误：

#15 11.25   Building wheel for fasttext (setup.py): finished with status 'error'
#15 11.26   error: subprocess-exited-with-error

我做错了什么？

根据文档，fastText 还需要 pybind11。你能否尝试将此软件包添加到你的 req.ini 中呢？ 文档链接：https://fasttext.cc/docs/en/python-module.html - Oguzhan Aygun

我已经将pybind11添加到req.ini中，但不幸的是，错误仍然存在。 - TheGainadl

您好，我已经拿到了您的Dockerfile和req.ini来复现问题。在错误的行中，它说：“RuntimeError：不支持的编译器--至少需要C++11支持！"因此，我添加了Dockerfile中的步骤“RUN apt-get install build-essential -y”，并且它成功构建了。您可以尝试一下这个方法吗？ - Oguzhan Aygun

好的，它起作用了。非常感谢您。由于我的帖子中没有太多文本，因此Stack不允许我发布整个错误，所以我不得不剪切那部分。 - TheGainadl

没问题，很高兴它起作用了 :) - Oguzhan Aygun

您可以将以下内容添加到 Dockerfile 中以获取 C++11 包：

RUN apt-get update &&\
    apt-get install --no-install-recommends --yes build-essential
