It appears that my max ports weren t configured correctly  I ran the following code and it worked      echo fs inotify max user watches 582222   sudo tee -a  etc sysctl conf  amp  amp  sudo sysctl -p   What this command does is to increase the number of watches allowed for a single user  By the default the number can be low  8192 for example   When nodemon tries to watch large numbers of directories for changes it has to create several watches  which can surpass that limit   You could also solve this problem by   sudo sysctl fs inotify max user watches 582222  amp  amp  sudo sysctl -p   But the way it was written first will make this change permanent

nodemon  Internal watch failed  watch  home Document nmmExpressServer bin ENOSPC npm ERR  code ELIFECYCLE npm ERR  errno 1 npm ERR  nmmexpressserver 0 0 0 start   nodemon   bin www  npm ERR  Exit status 1 npm ERR   npm ERR  Failed at the nmmexpressserver 0 0 0 start script    This is the error I got when running nodemon   bin www      The solution was closing an Atom window that had a entire directory of folders open in the project window    I don t know why  but I m assuming Atom and nodemon use similar processes to watch files folders

Erik  You can just kill all the other node processes by      pkill -f node   and then restart your server again  It ll work just fine then

I had the same error  but in Ubuntu 14 04 inside Windows 10  Bash on Ubuntu on Windows   All I did to overcome the error was to update the Creators update  which then allowed me to install 16 04 version of Ubuntu bash and then after installing newest version of node  by this steps  I installed also the newest version of npm and then the nodemon started to work properly

Instead of specifying a list of directories to ignore  e g  negative   you can also specify a list of directories to watch  e g positive    nodemon --watch dir1 --watch dir2  dir1 examples index js   In my particular case  I had one directory I wanted to watch and about nine I wanted to ignore  so specifying  --watch  was much simpler than specifying  --ignore

Try reopening VS code or Atom with more specific directory where your app js is present  I had a lot of folders opened and this problem occured  But once I opened my specific folder and tried once again  it worked

As per discussion over here  ENOSPC means Error No more hard-disk space available  Reason why this much memory required by nodemon or gulp-nodemon  in my case  is that it was watching contents of a folder which it shouldn t  To fix that nodemon has ignore setting that can be used to tell nodemon what not to watch  Have a look at nodemon sample config here

Add a nodemon json configuration file in your root folder and specify ignore patterns for example   nodemon json       ignore            test js         dist             Note that by default  git  node modules  bower components   nyc output  coverage and  sass-cache are ignored so you don t need to add them to your configuration    Explanation  This error happens because you exceeded the max number of watchers allowed by your system  i e  nodemon has no more disk space to watch all the files - which probably means you are watching not important files   So you ignore non-important files that you don t care about changes in them for example the build output or the test cases
