AttributeError: 'CGlobalDeclarations' object has no attribute 'capp'

[restarre]

Sorry to bother you.
I'm having problem running chc_analyze_project.py. It reported the following information.

CodeHawk-C-master/chc/cmdline/c_project$ python3 chc_analyze_project.py ~/Downloads/file-master  --verbose
Traceback (most recent call last):
  File "chc_analyze_project.py", line 170, in <module>
    capp = CApplication(sempath, contractpath=contractpath)
  File "~/CodeHawk-C-master/chc/app/CApplication.py", line 79, in __init__
    self.declarations = CGlobalDeclarations(self)
  File "~/CodeHawk-C-master/chc/app/CGlobalDeclarations.py", line 99, in __init__
    CDeclarations.__init__(self, CGlobalDictionary(self))
  File "~/CodeHawk-C-master/chc/app/CGlobalDictionary.py", line 44, in __init__
    self.capp = decls.capp
AttributeError: 'CGlobalDeclarations' object has no attribute 'capp'

How should I solve this problem? Are there any components that are not installed?
Looking forward to your answer.
