NFD does not run on a system without a created configuration file; by default, it looks for one at the path specified in the error message. If you are looking to run NFD standalone, please follow the docs here:

Mini-NDN has code which copies and modifies these files for individual nodes and provide necessary environmental variables/process separation/etc which is why it does not have this issue. </div>

<div>Hi Alex,
<div><br>
</div>
<div>Many thanks for your reply. I have another question. When I first installed mini-non, I’ve checked “nfd-status”, it seemed nfd works well at that time. However, now I found that nfd didn’t work and I’ve tried “nfd-start”. It gave me an error below. I wonder
how to solve the problem of nfd. Thanks a lot!</div>

I believe this is an issue with the nfdc helper code not handling the returned output for "face-updated" which is not treated as a failure internally in nfdc, we had observed this prior and noted it did not seem to be causing issues. I will try and push an
update ASAP as I believe this has caused confusion multiple times and I was able to find the apparent cause. However, I am reasonably confident that you are safe to ignore it until then.<br>

<div style="font-size:11pt">Hi all,<br>
<br>
I met an error when building an example to run nlsr on minindn. At last nlsr indeed converges. But there’re two faces fail to register before. I’ve attached the log below.<br>
