I have two versions Python-2.7, Python-3.5 which I was able to access with python(pip)
and python3(pip3)
command respectively. Then I have installed an another version of python (ie 3.7.5)
.
I have used these commands to install it.
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev
wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
tar xvf Python-3.7.5.tgz
cd Python-3.7.5
./configure --enable-optimizations --enable-shared
make -j6
sudo make altinstall
Everything was successful but the only issue is I was not able to access Python-3.7 using the command python3.7
.
When I used python3.7 it returned this following error:
python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
Can anyone please help me regarding how to fix this issue?
Info: OS
: Debian GNU/Linux 9.11 (stretch)
Output when I type:

You need to add /usr/local/lib/
to the library search path. You can call the following in the current shell before running python3.7
:
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
Or run ldconfig
to add the path to the linker cache:
sudo ldconfig /usr/local/lib
Thanks All for sharing, but none of these worked for me, instead I just installed the required library using:
sudo apt-get install libpython3.7
I'm using homebrew/linuxbrew to manage my latest python3 version. Doing this export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.3/lib
works for me (no reboot need).
If someone is still looking for a solution due to Pycharm IDE
Situation:
Weirdly enough it works if python script is executed from the terminal but as soon I use Pycharm IDE it shows above error
Solution:
What worked is a solution by @Vladstein Vomithler and @Dharman
I lack the understanding of the problem and why it occurred, it would be very helpful if someone can comment about that
