我有两个版本的Python-2.7和Python-3.5，分别可以通过python(pip)和python3(pip3)命令访问。然后，我安装了另一个版本的python (i.e 3.7.5)。
我已使用这些命令进行安装。
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
一切都成功，但是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：加载共享库时出错：libpython3.7m.so.1.0：无法打开共享对象文件：无此文件或目录
[有人可以帮助我解决此问题吗？

您需要在库搜索路径中添加/usr/local/lib/。您可以在运行python3.7之前在当前Shell中调用以下命令：
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
或运行ldconfig将路径添加到链接器缓存：
sudo ldconfig /usr/local/lib
