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

Then,

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

Output:

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

so, I ran

 docker run ubuntubr ls /usr/local/lib

Output

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

so why cant it find libpython2.7.so.1.0 when it exists in /usr/local/lib and how do i fix it?

thank you

Answer 1

You need to add /usr/local/lib to the list of directories that the linker searches at runtime, and run ldconfig . Append these 2 lines to your Dockerfile:

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

Then I test it with ubuntuapp:

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