Python pytest期间拒绝权限--travis ci中docker上的cov执行

我在travisci端docker上执行pytest命令时遇到问题。执行命令后：

docker exec my_package pytest --cov=/usr/local/lib/python3.7/site-packages/my_package tests/ -vvv

以下错误可见：

Dockerfile

FROM python:3.7

WORKDIR /code

RUN apt-get update && apt-get install -y musl-dev gcc postgresql

ADD requirements-test.txt /code/
RUN pip3 -r requirements-test.txt

COPY . /code
RUN pip3 install .

EXPOSE 5000

RUN useradd user
USER user

您是否尝试过运行

runuseradduser；用户用户

在运行apt get后？由于以root用户身份运行

COPY

，代码覆盖率结果可能无法写入root用户创建的文件夹，从而导致问题
