问题描述:

刚pull下来,首次启动,打开python用 import 验证服务缺漏情况;

pygame安装出错,Docker太精简,文本编辑服务都没安装,vim nano gedit等都not found,各种服务都无法安装和更新,(opencv:arm32v7 )连pip都没安装;有一个容器(opencv:arm32v7 ) curl正常,有一个容器(debian-opencv2)git正常还能用git clone,说明网络正常;

Reading package lists... Done
Reading package lists 没有显示进度,直接从0跳到下一步;

接着E: Unable to locate package **** ,报错,无法安装

 

树莓派3B+为Debian系统,通过cat 查看源;

root@4acc99961df5:/home/smart_car# sudo cat /etc/apt/sources.list
deb http://archive.raspbian.org/raspbian jessie main contrib non-free rpi firmware

 

dymat/opencv             arm32v7    31ee70a04dd8       db0562db6c8a 

dymat/opencv:arm32v7 

 

因为无法下载安装服务,无法更新,无法编写源,源码安装vim失败;所以只好直接docker cp,从主机 复制 sources.list 到容器对应目录;

 

首先进入容器,备份sources.list:

cd /etc/apt/
sudo mv /etc/apt/sources.list sources.list.bak

 

主机执行docker cp:

 

docker cp /etc/apt/sources.list 31ee70a04dd8:/etc/apt/

 

容器再apt-get更新:因为此容器还不能执行sudo,所以直接执行

apt-get update

必须更新两遍后才能安装服务,否则还出错;

安装pip:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

安装PIL.Image 图片,vim 文本编辑,游戏框架 pygame:

pip install pillow vim pygame

pillow 安装成功,vim 和 pygame 失败;

先search再安装pygame:

apt-cache search pygame
apt-get install python-pygame

同样方法,安装vim:

apt-cache search vim
apt-get install vim

完美解决!

docker cp /etc/apt/sources.list 4acc99961df5:/etc/apt/

 

list:正常显示进度

sudo apt-get upgrade 要更新两次才能正常,安装服务

 

 

因为很多测试程序都用到 cv模块,所以先解决OpenCV2.4的安装服务问题;

如果要安装python包,可以通过运行来搜索它是否在存储库中:

apt-cache search pygame

然后,您可以看到包(如果它们在存储库中)及其名称。输出apt-cache search pygame

root@4acc99961df5:/home# apt-cache search pygame
lightyears - single player real-time strategy game with steampunk sci-fi
psychopy - environment for creating psychology stimuli in Python
pyntor - flexible and componentized presentation program
python-pygame-sdl2 - reimplementation of the Pygame API using SDL2
python-pyglet - cross-platform windowing and multimedia library
python-soya-doc - high level 3D engine for Python
solarwolf - Collect the boxes and don't become mad
python-pygame - SDL bindings for games development in Python (Python 2)
python3-pgzero - Zero-boilerplate games programming framework based on Pygame (Python 3)
python3-pygame - SDL bindings for games development in Python (Python 3)
root@4acc99961df5:/home# sudo apt-get install python-pygame 

在此列表中,您可以选择包(此处:) python-pygame并运行sudo apt-get install the-package-name 

sudo apt-get install python-pygame

关依赖项的更多调试,请参阅使用pip安装pygame

完美解决!

印象中之前可以import cv2 和cv的,再测试后就报错;

ImportError: No module named cv2

试过直接apt-cache search cv2或cv,看了安装包感觉不大靠谱,按老规矩:

apt-cache search python-opencv
sudo apt-get install python-opencv

完美解决!
