python - 在 linux/sbin/ldconfig.real 上安装 opencv-python 时出错 :/usr/lib32/nvidia-384/libEGL. so.1 不是符号链接(symbolic link)

Question

我一直在按照本教程安装 opencv 和 python:

https://www.pyimagesearch.com/2015/06/22/install-opencv-3-0-and-python-2-7-on-ubuntu/#comment-441393

唯一的区别是我正在尝试安装 opencv 3.3.1 而不是 3.0.0

我在装有 Ubuntu 14.04、i7 和 NVIDIA GTX950M 的笔记本电脑上运行

问题是当我执行命令ldconfig

$ sudo make install
$ sudo ldconfig

我收到以下消息:

/sbin/ldconfig.real: /usr/lib/nvidia-384/libEGL.so.1 is not a symbolic link

/sbin/ldconfig.real: /usr/lib32/nvidia-384/libEGL.so.1 is not a symbolic link

于是我找到了解决问题的办法:

The following is an easy-to-use version of Noisy_Botnet's solution. It facilitates repeating the process for any update.

创建一个shell脚本，即将代码粘贴到一个文本文件下面，并以.sh扩展名保存。更改文件的执行权限，即转到终端中文件的位置并执行以下命令 $sudo chmod 744 nameofthefieleyoucreated.sh执行以下命令 $sudo ./nameofthefileyoucreated.sh

#! /bin/sh
#
# find the file in /usr/lib
LIBEGL=`find /usr/lib/nvidia* -name libEGL.so.\* | egrep "[0-9][0-9]*\.[0-9][0-9]*$"`
LIBEGL_LINK=`echo $LIBEGL | sed 's/[0-9][0-9]*\.[0-9][0-9]*$/1/'`
printf "\n\nThe following commands will be executed:\n+++++++++++++++++++++++++++++++++++++++\n"
printf "mv $LIBEGL_LINK ${LIBEGL_LINK}.orig\nln -s $LIBEGL $LIBEGL_LINK\n\n"
while true; do
    read -p "Do you wish to perform these commands?  " yn
    case $yn in
        [Yy]* ) mv $LIBEGL_LINK ${LIBEGL_LINK}.orig; ln -s $LIBEGL $LIBEGL_LINK ; break;;
        [Nn]* ) break;;
        * ) echo "Please answer yes or no.";;
    esac
done

# find the file in /usr/lib32
LIBEGL=`find /usr/lib32/nvidia* -name libEGL.so.\* | egrep "[0-9][0-9]*\.[0-9][0-9]*$"`
LIBEGL_LINK=`echo $LIBEGL | sed 's/[0-9][0-9]*\.[0-9][0-9]*$/1/'`
printf "\n\nThe following commands will be executed:\n+++++++++++++++++++++++++++++++++++++++\n"
