[英]Why does pip behave differently locally vs in a docker container?
So I have a requirements file that looks like this -所以我有一个看起来像这样的需求文件 -
aiohttp==3.5.4
aioredis==1.2.0
amqp==2.4.2
asn1crypto==0.24.0
astroid==2.1.0
async-timeout==3.0.1
atomicwrites==1.3.0
# so on...
I run我跑
pip install -r requirements.txt
locally and everything works fine.在本地,一切正常。
However, when I use this Dockerfile但是,当我使用这个 Dockerfile
FROM python:2.7-slim
WORKDIR /app
COPY . /app
# Install any needed packages specified in requirements.txt
RUN pip install -r requirements.txt
EXPOSE 80
ENV FLASK_APP=iterative.py
ENV FLASK_ENV=development
RUN pip install gunicorn
CMD ["gunicorn -w 4 app:app"]
I get this error -我收到此错误 -
Could not find a version that satisfies the requirement aiohttp==3.5.4 (from -r requirements.txt (line 1)) (from versions: 0.1, 0.2, 0.3, 0.4, 0.4.1, 0.4.2, 0.4.3, 0.4.4, 0.5.0, 0.6.0, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5, 0.7.0, 0.7.1, 0.7.2, 0.7.3, 0.8.0, 0.8.1, 0.8.2, 0.8.3, 0.8.4, 0.9.0, 0.9.1, 0.9.2, 0.9.3, 0.10.0, 0.10.1, 0.10.2, 0.11.0, 0.12.0, 0.13.0, 0.13.1, 0.14.0, 0.14.1, 0.14.2, 0.14.3, 0.14.4, 0.15.0, 0.15.1, 0.15.2, 0.15.3, 0.16.0, 0.16.1, 0.16.2, 0.16.3, 0.16.4, 0.16.5, 0.16.6, 0.17.0, 0.17.1, 0.17.2, 0.17.3, 0.17.4, 0.18.0, 0.18.1, 0.18.2, 0.18.3, 0.18.4, 0.19.0, 0.20.0, 0.20.1, 0.20.2, 0.21.0, 0.21.1, 0.21.2, 0.21.4, 0.21.5, 0.21.6, 0.22.0a0, 0.22.0b0, 0.22.0b1, 0.22.0b2, 0.22.0b3, 0.22.0b4, 0.22.0b5, 0.22.0b6, 0.22.0, 0.22.1, 0.22.2, 0.22.3, 0.22.4, 0.22.5, 1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.5, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5, 1.1.6, 1.2.0, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 2.0.0rc1, 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6.post1, 2.0.7, 2.1.0, 2.2.0, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.3.0a4, 2.3.0, 2.3.1, 2.3.2b2)
No matching distribution found for aiohttp==3.5.4 (from -r requirements.txt (line 1))
Moreover, my python version locally is 2.7.15.而且,我本地的python版本是2.7.15。
If I add如果我添加
RUN pip install aiohttp
I get this error when building构建时出现此错误
aiohttp requires Python '>=3.4.2' but the running Python is 2.7.16
So I have two questions -所以我有两个问题——
Thanks谢谢
Ok I solved this.好的,我解决了这个问题。
Ostensibly, the solution is to use a more modern version of python - I ended up using 3.6.表面上,解决方案是使用更现代的 python 版本——我最终使用了 3.6。
I think what was happening though was that pip was using python3, while python command lined was version 2.7.15.我认为发生的事情是 pip 使用的是 python3,而 python 命令行是 2.7.15 版。
