我正在努力迁移在 Python 2.7 上运行的旧版 Django 1.6 应用程序。我仍然需要能够运行这个在 docker 容器内运行的项目。
我面临的问题是项目的requirements.txt 文件只有在我设置虚拟环境时才会安装，即使是在docker 容器内！
谁能告诉我为什么无法在虚拟环境之外安装？
# Use a base image that supports Python 2.7 (required for Django 1.6)
FROM ubuntu:16.04
# Create and set the working directory inside the container
WORKDIR /app
# Copy the project's requirements.txt file to the working directory
COPY requirements.txt /app
# Install some OS requirements
RUN apt-get update && \
apt-get install -y wget build-essential git libpq-dev libxslt1-dev procps python \
python-pip python-dev memcached libmemcached-tools postgresql-client apt-file zlib1g-dev \
libjpeg-dev libxml2-dev libffi-dev libmysqlclient-dev
WORKDIR /app
COPY . /app
# Install project dependencies
RUN pip install --upgrade "pip < 21.0" && pip install virtualenv
# This will fail to complete
# RUN bash -c "pip install --no-cache-dir -r requirements.txt"
# This installs successfully
RUN bash -c "virtualenv /root/venv && source /root/venv/bin/activate && pip install --no-cache-dir -r requirements.txt"
这是我的 requirements.txt 文件，下面是我尝试在没有

现在我最初认为这与缺乏预制轮子有关（事实上我使用的是Apple M2芯片），但使用
virtualenv我尝试注释掉

这个更奇怪，因为如果我简单地在容器外壳上输入
requests<3.0,>=2.20.0pip install requests<3.0,>=2.20.0请帮忙！
试试这个。
