gef missing is telling me I'm missing packages

[hugsy]

GEF has no dependency : it works out-of-the-box !! You can safely ignore this warning and enjoy GEF

However, some more advanced optional features use 3rd party packages. Those are not mandatory but if you wish to use those functionalities and GEF tells you some packages are missing, it means the the Python version used by GDB cannot find those 3rd party package(s).

Example:

gef➤  gef missing
[*] Command `set-permission` is missing, reason  →  Missing `keystone-engine` package, install with: `pip install keystone-engine`.
[*] Command `assemble` is missing, reason  →  Missing `keystone-engine` package for Python, install with: `pip install keystone-engine`.

For 99.9% of cases, download and execute this script and now you should see

gef ➤  gef missing
[+] No missing command

For other cases, you must install manually packages for the Python version that GDB uses. To know which version is very, GEF displays this information every time it starts:

$ gdb -q /bin/ls
[...]
91 commands loaded for GDB 9.2 using Python engine 3.8
[...]

You can use pip or manually install those packages for this version.

Note: As an installation issue, do not file an Issue if you fail to install a package. It will be closed without answer. If you're positive there's a mistake (which there likely isn't), drop by our IRC/Discord/etc. first and talk to the developers.
