parseJuncInfo_th2() takes exactly 2 arguments (3 given)

Hi，I'm running fusionfusion using tophat2 mapped bam samples, and I get the following problems, I don't understand what's wrong?
fusionfusion --th2 accepted_hits.bam --refe rence_genome ucsc.hg19.fasta --out dir
Traceback (most recent call last):
File "fusionfusion", line 82, in

File "/home/.local/lib/python2.7/site-packages/fusionfusion/run.py", line 164, in main
parseJunctionInfo.parseJuncInfo_th2(output_dir + "/th2.chimeric.sam", output_dir + "/th2.chimeric.tmp.txt", args.abnormal_insert_size)
