Resolve importerror:lib*** so--cannot open shared object file: No such... (pycharm/clion reports an error but the shell does not)

Problem description ： After successful compilation （ There are executable files in the folder ）, Operation error reporting （Ubuntu）Clion The error cannot be found .so Shared library （ but shell Can be executed normally ） terms of settlement （pycharm The same goes for similar error reports ）

/home/luoxinhao/Desktop/mywork/bin/Infantry: error while loading shared libraries: libopencv_features2d.so.4.5: cannot open shared object file: No such file or directory

reason ：clion The implementation of may be similar to us shell The environment variables are different , Here's the solution

Method 1： Each start Clion Start without mouse , Use terminal , Get into clion In the folder , Input ./clion.sh, Can be executed normally .（ Feasible but troublesome ）

Method 2： Soft link mode （shell Reporting errors and IDLE Error reporting is feasible , But you may need to link many libraries , One link at a time ）

my clion It was successfully modified in this way , however pycharm After linking sevenoreight links, I gave up without finishing the chain

    1.1 file found

            find  /  -name  lib**.so   ( Missing DLL )  

    1.2 Build soft links

            ln -s  /path/to/lib**.so   /usr/lib

     1.3 sudo ldconfig

Method 3： modify LD_LIBRARY_PATH（ For me, it can only solve shell Report errors , After modification IDLE Still reporting a mistake ）

sudo gedit ~/.bashrc

export LD_LIBRARY_PATH=/where/you/install/lib:$LD_LIBRARY_PATH

sudo source ~/.bashrc

Method 4： modify /etc/ld.so.conf（ ditto ）

vim  /etc/ld.so.conf

add  /where/you/install/lib

sudo ldconfig

Method 5： Add to environment variable （ You can use , For resolution IDLE Report errors , You may need a matching method 3 Use , Not tried alone ）

Start by opening pycharm, Modify the environment variables of the running configuration in the upper right corner

If you already have environment variables , Put a semicolon in the back and paste .

The paste content is similar to the method 3

Such as method 3 The contents are as follows

export LD_LIBRARY_PATH="/opt/intel/openvino_2021.4.689/opencv/lib:$LD_LIBRARY_PATH"

Add... After the semicolon

LD_LIBRARY_PATH=/opt/intel/openvino_2021.4.689/opencv/lib
