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

我已经使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

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

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：没有这样的文件或目录

任何人都可以帮助我解决这个问题吗？

Answer 1

您需要添加/usr/local/lib/到库搜索路径。您可以在运行之前在当前 shell 中调用以下内容python3.7：

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

或者运行ldconfig以将路径添加到链接器缓存：

sudo ldconfig /usr/local/lib 

Answer 2

我刚刚使用以下方法安装了所需的库：

sudo apt-get install libpython3.7
