【问题描述】*：
在 /etc/profile 与 .bashrc里都加了：

export DM_HOME=/opt/dmdbms
export PATH=$DM_HOME/bin:$PATH
export LD_LIBRARY_PATH=$DM_HOME/bin:$LD_LIBRARY_PATH

在终端 echo $PATH 与 echo $LD_LIBRARY_PATH都能看到：

/opt/dmdbms/bin

ldd dmPython.cpython-38-x86_64-linux-gnu.so 得到

python3 进入console,再 import dmPython 也没有任何问题：

[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dmPython
>>> 

但代码中import dmPython就有错误：

Traceback (most recent call last):
  File "chengde/source/app.py", line 7, in <module>
    import urls
  File "/home/guest/chengde/source/urls.py", line 4, in <module>

  File "/home/guest/chengde/source/handlers/__init__.py", line 4, in <module>

    from models import async_db
  File "/home/guest/chengde/source/models/async_db.py", line 12, in <module>
    import dmPython

这是为什么呢？
