问题描述
我当前正在尝试使用Docker运行应用程序，但是在启动应用程序时收到以下错误消息：
error while loading shared libraries: libopencv_highgui.so.4.4: cannot open shared object file: No such file or directory
我假设docker文件中出现问题，并且安装未完成或不正确。因此，我在文章末尾添加了有关OpenCV的部分。 我是否错过了重要的步骤或dockerfile中的错误？

解决方法
在带有Python映像的Docker中安装OpenCV之前，我面临着同样的问题。您可能不需要太多的依赖关系，但这是一个选择。我将拥有适合我的情况的轻巧版本。请尝试以下代码：
重载版本：
FROM python:3.7
RUN apt-get update \
&& apt-get install -y \
build-essential \
cmake \
git \
wget \
unzip \
yasm \
pkg-config \
libswscale-dev \
libtbb2 \
libtbb-dev \
libjpeg-dev \
libpng-dev \
libtiff-dev \
libavformat-dev \
libpq-dev \
&& rm -rf /var/lib/apt/lists/*
RUN pip install numpy
WORKDIR /
ENV OPENCV_VERSION="4.1.1"
# install opencv-python from its source
RUN wget https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip \
&& unzip ${OPENCV_VERSION}.zip \
&& mkdir /opencv-${OPENCV_VERSION}/cmake_binary \
&& cd /opencv-${OPENCV_VERSION}/cmake_binary \
&& cmake -DBUILD_TIFF=ON \
-DBUILD_opencv_java=OFF \
-DWITH_CUDA=OFF \
-DWITH_OPENGL=ON \
-DWITH_OPENCL=ON \
-DWITH_IPP=ON \
-DWITH_TBB=ON \
-DWITH_EIGEN=ON \
-DWITH_V4L=ON \
-DBUILD_TESTS=OFF \
-DBUILD_PERF_TESTS=OFF \
-DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=$(python3.7 -c "import sys; print(sys.prefix)") \
-DPYTHON_EXECUTABLE=$(which python3.7) \
-DPYTHON_INCLUDE_DIR=$(python3.7 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
-DPYTHON_PACKAGES_PATH=$(python3.7 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") \
.. \
&& make install \
&& rm /${OPENCV_VERSION}.zip \
&& rm -r /opencv-${OPENCV_VERSION}
RUN ln -s \
/usr/local/python/cv2/python-3.7/cv2.cpython-37m-x86_64-linux-gnu.so \
/usr/local/lib/python3.7/site-packages/cv2.so
RUN apt-get --fix-missing update && apt-get --fix-broken install && apt-get install -y poppler-utils && apt-get install -y tesseract-ocr && \
apt-get install -y libtesseract-dev && apt-get install -y libleptonica-dev && ldconfig && apt install -y libsm6 libxext6 && apt install -y python-opencv
轻量级版本：
FROM python:3.7
RUN apt-get update -y
RUN apt-update && apt install -y libsm6 libxext6
就我而言，我最终使用了繁重的版本，只是为了节省一些麻烦，并且两个版本都可以正常工作。供您参考，也请参阅this link，并感谢Neo Anderson的大力帮助。
,apt-get update -y
apt install -y libsm6 libxext6
apt update
pip install pyglview
apt install -y libgl1-mesa-glx
