bin/gs_startnode fails to start on GridDB version 4.3.0

> System: ubuntu18.04 > > version:4.3.0 griddb-4.3.0.tar.gz I tried to compile and install the 4.3.0 version on ubuntu18.04. After compiling and installing, executing bin/gs_ Startnode, the program has an error, and the python 2.7 version is used. Is it the Python version? wdgk@ubuntu:~/application/griddb/griddb-4.3.0$ bin/gs_startnode Traceback (most recent call last): File "bin/gs_startnode", line 122, in proc = subprocess.Popen(command, stdout=f, stderr=f) File "/usr/lib/python2.7/subprocess.py", line 394, in __init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1047, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory
