由于 python greenlet 包，Docker 构建崩溃

如何解决由于 python greenlet 包，Docker 构建崩溃

我正在尝试从现有的 Dockerfile 创建一个 Docker 容器，但由于 greenlet 包而失败。这个容器是以前（1-2 年前）构建的，并且在远程服务器上运行良好，但是当我尝试在本地或其他云机器上再次构建时，它失败了。非常感谢任何帮助。

这是 Dockerfile

FROM python:2.7-alpine

RUN apk update && apk add \
        postgresql-dev \
        python3-dev \
        gcc \
        jpeg-dev \
        zlib-dev \
        musl-dev \
        linux-headers && \
        mkdir app

workdir /app/

# Ensure that Python outputs everything that's printed inside
# the application rather than buffering it.
ENV PYTHONUNBUFFERED 1

ADD . /app

RUN if [ -s requirements.txt ]; then pip install -r requirements.txt; fi
EXPOSE 8092
VOLUME /app/auction/assets
ENTRYPOINT ["/usr/local/bin/uwsgi","--ini","/app/uwsgi.ini"]

这是我得到的错误：

解决方法

我遇到了同样的问题，但使用基本 Python 映像 python:3.7.4-alpine3.10。最近发布的 SQLAlchemy 版本似乎是问题的根源。

为了解决这个问题，我只是从需求文件中删除了包并构建了一个空容器。我单独运行了安装，发现 SQLAlchemy 及其依赖项需要固定到以前的版本。

我的需求文件失败了：

Flask==1.1.2
Flask-Ext==0.1
Flask-Script
flask-cors
flask-login
Flask-Migrate
mysql-connector-python
python-dotenv
sqlalchemy
pytest-flask

已安装的更新版本：

Flask==1.1.2
Flask-Ext==0.1
Flask-Script
flask-cors
flask-login
Flask-SQLAlchemy==2.4.4
Flask-Migrate==2.6.0
mysql-connector-python
python-dotenv
sqlalchemy==1.3.23
pytest-flask
