Some newbie questions about Nix package manager on Debian

I’m loving Nix, but there is some shit I didn’t find on wiki.

After Nix install, I wasn’t able to call Nix from bash. I have to set PATH manually every time I open a new tab on terminal.

$ . $HOME/.nix-profile/etc/profile.d/

Since source prefix/etc/profile.d/ didn’t work, I had tried to include export PATH=$PATH:~/.nix-profile/etc/profile.d/ on .bashrc and .profile, but don’t work.

  1. When some package need to read some file from /home, how this works? I must fix ugly fonts on Firefox with ~/.fonts.conf file but didn’t work.

  2. Bleachbit didn’t run and I find this on official site:

On Fedora, Red Hat, CentOS, and openSUSE, the symptom is either BleachBit does not start or you get the error ImportError: No module named gi in the console. The solution is to install the package python2-gobject.

I installed python2.7-pygobject-3.32.1, but nothing. What to do in this case?
