Docker：libpython2.7.so.1.0：无法打开共享对象文件：没有这样的文件或目录

Question

Dockerfile

FROM python:2.7 as python
CMD ["bash"]

FROM ubuntu
COPY --from=python /usr/local /usr/local

然后，

docker build -t ubuntuapp .
docker run ubuntuapp /usr/local/bin/python

输出：

local/bin/python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

所以，我跑了

 docker run ubuntubr ls /usr/local/lib

产量

libpython2.7.so
libpython2.7.so.1.0
pkgconfig
python2.7

那么为什么它在/ usr / local / lib中存在时无法找到libpython2.7.so.1.0，我该如何解决？

谢谢

Answer 1

您需要将/ usr / local / lib添加到链接器在运行时搜索的目录列表中，然后运行ldconfig。将这两行附加到Dockerfile：

RUN echo /usr/local/lib > /etc/ld.so.conf.d/local.conf && \
    ldconfig

然后我用ubuntuapp测试它：

$ docker run --rm -it test /usr/local/bin/python
