Docs update / Installation through pip not working

[mariobaldini]

When I tried to install b2 through pip, following the README of this repository, the installation itself works but the command is not found (even after terminal restart)

mario@latitude:~$ 


mario@latitude:~$ b2

Command 'b2' not found, but can be installed with:

sudo apt install libboost1.67-tools-dev
sudo apt install libboost1.65-tools-dev

mario@latitude:~$ 

I can only install the tool using the instructions found here: https://www.backblaze.com/b2/docs/quick_command_line.html

mario@latitude:/arquivos/sdk/B2_Command_Line_Tool$ b2 version
b2 command line tool, version 1.3.9
mario@latitude:/arquivos/sdk/B2_Command_Line_Tool$ 

Which worked just fine.

I think the README.md of this repo could be updated with the instruction that works (install from git clone), or changed for the pip install work -- so people that land here directly can easily install it.

I had the same issue. It seems to be a missing dependency in the arrow package (as discussed here arrow-py/arrow/issues/495).

A simple pip install backports.functools_lru_cache should fix it.
