1 year ago The problem is on the first line:
#!/usr/bin/python
There is no such file on your system.
You can fix this by installing a package:
sudo apt install python-is-python3
The script could be changed to use #!/usr/bin/python3, but there may be systems on which that doesn't exist.
Hi, I am new to bcc. I just setup bcc in ubuntu 22.04 LTS and tried to run hello_world.py in /bcc/examples. In this file, file says that this file will run with 'sudo ./hello_world' in /bcc/examples. But when I tried it, there was error log
'sudo: unable to execute ./hello_world.py: No such file or directory'
So, I tried with 'sudo python3 hello_world.py' and it worked with these logs.
b' systemd-udevd-18460 [001] d...1 15447.848709: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [000] d...1 15447.858894: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [000] d...1 15447.878289: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [000] d...1 15447.893018: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [001] d...1 15447.909810: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [001] d...1 15447.929566: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [001] d...1 15447.952344: bpf_trace_printk: Hello, World!' b'' b' systemd-udevd-33399 [001] d...1 15447.966791: bpf_trace_printk: Hello, World!' b''
But since it didn't exit, I interrupted with ctrl + c. Now I am wonder what was the problem. Does hello world make error since there was some error in my bcc setup, or the command 'sudo ./hello_world.py' was wrong in ubuntu 22.04LTS?
