Question

我正在将opencv库用于Node，并且在Linux上遇到了一些奇怪的路径问题

仅发出require('opencv');时，出现以下错误：

Error: libopencv_dnn.so.3.4: cannot open shared object file: No such file or directory
    at Object.Module._extensions..node (internal/modules/cjs/loader.js:730:18)
    at Module.load (internal/modules/cjs/loader.js:600:32)
    at tryModuleLoad (internal/modules/cjs/loader.js:539:12)
    at Function.Module._load (internal/modules/cjs/loader.js:531:3)
    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:22:18)

我看着binding.gyp，如果我执行find-opencv.js实用程序，我会得到似乎的答案：

/usr/src/app/node_modules/opencv# node utils/find-opencv.js --libs
-L/usr/local/lib -lopencv_dnn -lopencv_ml -lopencv_objdetect -lopencv_shape -lopencv_stitching -lopencv_superres -lopencv_videostab -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video -lopencv_photo -lopencv_imgproc -lopencv_flann -lopencv_core

我可以在其中看到 opencv_dnn ，如果我ls libs目录：

ls -l /usr/local/lib | grep dnn
lrwxrwxrwx 1 root root        20 Mar 20 17:23 libopencv_dnn.so -> libopencv_dnn.so.3.4
lrwxrwxrwx 1 root root        22 Mar 20 17:23 libopencv_dnn.so.3.4 -> libopencv_dnn.so.3.4.5
-rw-r--r-- 1 root root  12970608 Mar 20 17:20 libopencv_dnn.so.3.4.5

我看到 libopencv_dnn.so.3.4 确实存在。

不确定我下一步是什么...

好的，因此运行ldconfig似乎可以“解决”问题

错误：libopencv_dnn.so.3.4：使用node-opencv时无法打开共享对象文件
