Update the following lines in the annotator.py
line 384 : dr.sort ->> dr.memory_data.sort line 385 : dr.insn_addr ->> dr.memory_data.insn_addr line 385 : dr.content ->> str(dr.memory_data.content)
Thank you very much, It works, But I found that the second line should be changed to this
> line 385 : dr.insn_addr ->> dr.ins_addr
because if I change it like you, It will have the following problems

In addition，when I run the sample code, I had the same problem as #32
def main(filename):
proj = angr.Project(filename, load_options={'auto_load_libs': False})
main = proj.loader.main_object.get_symbol("main")
start_state = proj.factory.blank_state(addr=main.rebased_addr)
cfg = proj.analyses.CFGEmulated(fail_fast=True, starts=[main.rebased_addr], initial_state=start_state)
plot_cfg(cfg, "ais3_cfg", format='png', asminst=True, remove_imports=True)
but I run my code, it will output normally
def cfgfastpng(filename):
proj = angr.Project(filename, auto_load_libs=False)
cfg = proj.analyses.CFGFast()
plot_cfg(cfg, "cfg", format='png', asminst=True, remove_imports=True)

Sorry for my late reply. Thanks for the report and the solution, I will apply the fixes on the weekend.
@mz21g :
When #32 was reported, I've tried to check it, but it worked for me.
Could you maybe figure out what is causing the problem? I wrote some thoughts about how to debug it in the original ticket.
I will also try to retest that on the weekend.

I've applied the fix and created a new PyPI version. Thanks for the report!
@mz21g Tried your code to test #32, but it creates the assembly listing for me.
