在Docker构建中使用pip安装时出现ModuleNotFoundError

如何解决在Docker构建中使用pip安装时出现ModuleNotFoundError

因此，我遇到了许多讨论此特定问题的话题，但无法真正找到适合我的解决方案。

我在根目录下的requirements.txt文件中总结了以下要求

"cmakeExecutable":
"C:\\Users\\myname\\AppData\\Local\\Android\\Sdk\\cmake\\3.10.2.4988404\\bin\\cmake.exe",

我的src / app.py开始为

stripe==2.51.0
bottle==0.12.18

我正在使用Dockerfile构建映像，如下所示：

from bottle import route,run,template,get,post,request,response,static_file
import stripe

# rest of the code I assume isn't relevant

即使我在将根路径添加到最终路径中的同时使用了# build 1 FROM python:3.8.5 AS builder COPY requirements.txt . RUN python -m pip install --user -r requirements.txt # build 2 FROM python:3.8.5-slim COPY --from=builder /root/.local/bin /root/.local COPY ./src . EXPOSE 8080 ENV PATH=/root/.local:$PATH CMD [ "python","app.py" ] ，但仍然出现以下错误：

--user

我也-我认为-在安装和运行程序包时使用相同的解释器，所以我真的不知道如何解决此问题。

任何朝着正确方向的指针将不胜感激。

感谢很多人！

解决方法

进行以下更改：

COPY --from=builder /root/.local /root/.local

ENV PATH=/root/.local/bin:$PATH

建议：使用slim-buster，您的Dockerfile可能会这样结束：

FROM python:3.8.5-slim-buster AS base

FROM base AS builder
COPY requirements.txt .
RUN python -m pip install --user -r requirements.txt

FROM base AS release
COPY --from=builder /root/.local /root/.local
COPY ./src .
EXPOSE 8080
ENV PATH=/root/.local/bin:$PATH
CMD [ "python","app.py" ]

,

能够下载

stripe==2.51.0
bottle==0.12.18

具有给定的dockerfile和requirements.txt。

将Dockerfile和requirements.txt放在同一文件夹中，并在本地计算机上安装docker-desktop并运行“ docker build”。从cmd中的该文件夹中，该文件夹将用于本地构建docker映像。 收到日志：

还尝试将docker文件更新为 Dockerfile

# build 2
FROM python:3.8.5-slim
ADD requirements.txt /
ENV PATH=/root/.local/bin:$PATH
RUN pip install --user -r requirements.txt
COPY ./src .   #### 

EXPOSE 8080
ENV PATH=/root/.local:$PATH ###not sure of the use####
