ImportError: cannot import name BPF

[britchey80]

4.9.0-8-amd64 #1 SMP Debian 4.9.144-3 (2019-02-02) x86_64 GNU/Linux

After following the installation instructions for Debian here:
https://github.com/iovisor/bcc/blob/master/INSTALL.md#debian---source

I am unable to run any of the tools. They all fail with the error message:

from bcc import BPF
ImportError: cannot import name 'BPF'

Here are my current kernel BPF configs:

cat /boot/config-4.9.0-8-amd64 | grep BPF
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
# CONFIG_BPF_JIT_ALWAYS_ON is not set
CONFIG_NETFILTER_XT_MATCH_BPF=m
CONFIG_NET_CLS_BPF=m
CONFIG_NET_ACT_BPF=m
CONFIG_BPF_JIT=y
CONFIG_HAVE_EBPF_JIT=y
CONFIG_BPF_EVENTS=y
CONFIG_TEST_BPF=m

Any help would be appreciated.

I also encounter this same issue on Ubuntu 18.04 when using the installed tools..

bwalker@brads-T460s:~$ apt list --installed | grep bpfcc-tools

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

You need to install python-bcc or python3-bcc

[grantseltzer]

I am still getting this issue

[jackice]

I also encounter this same issue on centos8 when using the installed python3-bcc

dnf list --installed
bcc.x86_64 0.11.0-2.el8 @appstream
bcc-tools.x86_64 0.11.0-2.el8 @appstream
python3-bcc.x86_64 0.11.0-2.el8 @appstream

Try running it with 'sudo su' -

[wzhliang]

I had this problem but managed to make it disappear with pip3 uninstall bcc

[yueyongyue]

python2.7 ok python3 unsuccessful

[yonghong-song]

Look at Install.md file. You may need to build bcc with PYTHON_CMD option like

cmake .. -DPYTHON_CMD=python3 # for python3 support

FWIW - in my case it turns out that sudo /bin/python3 /usr/share/bcc/tools/execsnoop works.

python3 resolves (as per $PATH) to ~/.pyenv/shims/python3 in my case - it is 3.8.8 .. same as /usr/bin/python, needed for https://github.com/elastic/rally

/bin/python3 is the "system's" i.e. CentOS 8.3 distribution's 3.6.8

[gpstrive]

use 'apt install python3-bpfcc ' ,
'pip3 install bcc' not works

[JiaHuann]

use 'apt install python3-bpfcc ' ,
'pip3 install bcc' not works

[minhtrex]

I tried on AlmaLinux9.
worked: 'sudo yum install python3-bcc '
not worked: 'pip3 install bcc'

I also had this problem using python3.9.
When I exec "yum install python3", it will install python3.6，it won't this problem.
