Python3.7：加载共享库时出错：libpython3.7m.so.1.0

Question

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:

Answer 1

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 

Answer 2

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

Answer 3

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).

Answer 4

If someone is still looking for a solution due to Pycharm IDE

Situation:

• OS: ubuntu 18.04.4
• This Problem occurred after the installation of caffe (cuda).

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
