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

Question

我有两个版本Python-2.7，Python-3.5，我可以分别使用python(pip)和python3(pip3)命令访问它们。然后我安装了python (i.e 3.7.5)的另一个版本。

我用这些命令来安装它。

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

一切都很成功，但唯一的问题是我无法使用命令python3.7访问Python-3.7。

当我使用python3.7时，它返回以下错误：

python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory

有谁能帮我解决这个问题吗？

您需要将/usr/local/lib/添加到库搜索路径。在运行python3.7之前，可以在当前shell中调用以下命令：

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib

或者运行ldconfig将路径添加到链接器缓存：

sudo ldconfig /usr/local/lib
