python - PyKEP python 开普勒工具箱

Question

我按照安装 python keplerian 工具箱的说明进行操作，一切顺利，但在尝试导入模块时出现问题。

我遵循的说明:keptoolbox

有人知道我该如何解决这个问题吗？

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/PyKEP/__init__.py", line 1, in <module>
    import core, sims_flanagan
  File "/usr/local/lib/python2.7/dist-packages/PyKEP/core/__init__.py", line 2, in <module>
    from _core import *
ImportError: libkeplerian_toolbox.so: cannot open shared object file: No such file or directory

文件libkeplerian_toolbox.so位于/usr/local/lib/libkeplerian_toolbox.so。我需要复制到其他地方吗？

所有内容都安装在正确的目录中:

这是一个链接问题，ldconfig默认不会在/usr/local/lib中查找，所以你需要将其添加到文件/etc/ld.so.conf (只需将其放在 include 语句下即可)。现在运行

ldconfig

错误应该消失了。
