我想在Docker映像中安装python3.5的zbarlightpython包。在
Dockerfile如下所示
FROM python:3.5
WORKDIR /app
ADD . /app
RUN pip3 install -r requirements.txt
EXPOSE 80
CMD ["python", "main.py"]
在要求.txt文件如下
^{pr2}$错误如下。在
gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/usr/local/include/python3.5m -c src/zbarlight/_zbarlight.c -o build/temp.linux-x86_64-3.5/src/zbarlight/_zbarlight.o -std=c99
src/zbarlight/_zbarlight.c:3:18: fatal error: zbar.h: No such file or directory
#include <zbar.h>
^
compilation terminated.
error: command 'gcc' failed with exit status 1
然后我通过本地安装libzbar dev
sudo apt-get install libzbar-dev
然后在本地尝试以下命令。在
dpkg -L libzbar-dev
对上述命令的响应

第二个命令
ls -l /usr/include/zbar.h
上述命令的响应。在
-rw-r--r-- 1 root root 47339 Jan 28 2016 /usr/include/zbar.h
然后在Dockerfile中添加前两行。在
FROM ubuntu:16.04
RUN apt-get update; apt-get install -yV libzbar0 libzbar-dev; dpkg -L libzbar-dev; ls -l /usr/include/zbar.h; apt-get update
FROM python:3.5
WORKDIR /app
ADD . /app
RUN pip install -r requirements.txt
EXPOSE 80
CMD ["python", "main.py"]
在构建docker图像时很少有重要的屏幕截图。在
我修改了我的Dockerfile如下。在
当我改变主意使用python3.5的官方Docker映像时,我将Python作为一个包安装。 并更改了默认的python版本(modified soft link)。在
