我正在使用的教程如下： https ://heasarc.gsfc.nasa.gov/xanadu/xspec/python/html/buildinstall.html

我已经完成安装直到..Once HEASOFT is finished building and installing, you should find PyXspec’s code files and lib_pyXspec.so library in the directory $HEADAS/lib/python/xspec.

但是，当我运行时$HEADAS/headas-init.csh，它要求超级用户权限，当我使用时sudo，它给我一个错误，说找不到命令。然后我尝试使用以下方法手动设置 PYTHONPATH 环境：

>>> sys.path
['', '/usr/local/lib/python2.7/dist-packages/pyds9-1.9.dev0-py2.7-linux-x86_64.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
>>> 
>>> sys.path.append("$HEADAS/lib/python")
>>> import xspec
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "xspec/__init__.py", line 66, in <module>
    from .chain import ChainManager, AllChains, Chain
  File "xspec/chain.py", line 4, in <module>
    from . import _pyXspec
ImportError: libXSUser.so: cannot open shared object file: No such file or directory

但这也不起作用。我该如何安装？

谢谢

从我正在阅读的内容来看，这可能是 sys.path 执行搜索方式的问题。
我能找到的关于此事的两个最相关的帖子是：

为什么 Python 找不到 sys.path 目录中的共享对象？
