Vim-LatexSuite: /bin/bash: latex command not found

TeXLive 2015: I installed TeXLive 2015 following the simplest instruction sudo ./install-tl-ubuntu (without any options) of scottkosty/install-tl-ubuntu@GitHub.

Vim-Latex-Suite: I installed Vim-Latex-Suite following these Installation Instructions, including these recommended settings.

However, \ll (to compile .tex in Latex-Suite) does not work.
The command :!latex -interaction=nonstopmode % shows

/bin/bash: latex: command not found
shell returned 127 

My current configurations:

echo $PATH in ubuntu shows:

/opt/texbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

:echo $PATH in vim shows:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

which latex shows /opt/texbin/latex;
and latex --version shows

Two methods which do not work:

1. Adding export PATH=$PATH:/opt/texbin/ to file .bashrc

2. The method from TeX Live and vim-latexsuite PATH problems does not work for me:

   $ cat /etc/profile.d/latex.sh
   export PATH="${PATH}:/usr/local/texlive/2015/bin/x86_64-linux"

ADDED: By the way, in my another Ubuntu system with latex installed in another way, which latex gives /usr/bin/latex and vim-latex works.

The script sudo ./install-tl-ubuntu will install latex at /opt/texbin, where is not a default path(/usr/local/texlive/2015/bin/x86_64-linux) for latex.

It seems you have installed two latex, any one of them should work in case you set their corresponding $PATH in .bashrc.

I note that your shell and vim have different $PATH. Vim cannot find latex with it’s $PATH. It is not likely that you started vim in an old shell as you restarted your computer. I guess you run vim with sudo, as sudo uses root's environment, where usually keeps a default $PATH, exactly the same value in your vim.
