Had the same problem otherwise was just working fine a day ago  Very simple fix first check if nodemon exists on your system globally or not      To check   npm list -g --depth 0   If you don t see then install  it npm install -g nodemon  g stands for globally   If you see it still doesn t work then you need to configure environment variable I use Windows OS  On Windows navigate to   Control panel gt System gt Advanced System Settings gt Environment Variables gt double-click on PATH   Now check if you have this PATH C  Users yourUsername AppData Roaming npm If not  you will see some existing paths  just append to it separating with semicolon  That s it  Worked for me   For me node was installed in C    Roaming npm and for you if the PATH is different  you will put in whatever applcable

heroku runs in a production environment by default so it does not install the dev dependencies   if you don t want to reinstall nodemon as a dependency which I think shouldn t because its right place is in devDependencies not in dependencies   instead  you can create two npm script to avoid this error by running nodemon only in your localhost like that    scripts          test    echo   Error  no test specified    amp  amp  exit 1        start    node app js        start dev    nodemon --watch       and when you want to run the project locally just run in your terminal npm run start dev and it will load app js by nodemon   while in heroku npm start runs by default and load app js from a normal node command and you get rid of that error

This solution had worked for me    I assume that you have installed nodemon globally  If it s done follow this steps     open your  bash profile file   nano  bash profile   past this to add a new alias in your bash profile   alias nodemon     npm-global lib node modules nodemon bin nodemon js    Now you can use nodemon command anywhere

Try to check installed global packages npm list -g --depth 0  If you will not find nodemon  - install it with flag -g or --save-dev  Don t install nodemon with flag --save  because nodemon uses only for development

I wanted to add how I fixed this issue  as I had to do a bit of mix and match from a few different solutions  For reference this is for a Windows 10 PC  nodemon had worked perfectly for months and then suddenly the command was not found unless run locally with npx   Here were my steps -    Check to see if it is installed globally by running npm list -g --depth 0  in my case it was installed  so to start fresh     I ran npm uninstall -g nodemon Next  I reinstalled using npm install -g --force nodemon --save-dev  it might be recommended to try running npm install -g nodemon --save-dev first  go through the rest of the steps  and if it doesn t work go through steps 2  amp  3 again using --force   Then I checked where my npm folder was located with the command npm config get prefix  which in my case was located at C  Users username AppData Roaming npm I modified my PATH variable to add both that file path and a second entry with  bin appended to it  I am not sure which one is actually needed as some people have needed just the root npm folder and others have needed bin  it was easy enough to simply add both  Finally  I followed similar directions to what Natesh recommended on this entry  however  with Windows  the  bashrc file doesn t automatically exist  so you need to create one in your   directory  I also needed to slightly alter how the export was written to be export PATH  PATH  C  Users username AppData Roaming npm   Obviously replace  username  with whatever your username is  or whatever the file path was that was retrieved in step 4    I hope this helps anyone who has been struggling with this issue for as long as I have

under your current project directory  run   npm install nodemon --save   save in package json so that the following code cam find your nodemon   then under  scripts  in your package json file  add  start    nodemon app js   or whatever your entry point is  so it looks like this    scripts          test    echo   Error  no test specified    amp  amp  exit 1        start    nodemon app js      and then run  npm start   That avoids complicate PATH settings and it works on my mac hope can help you

I found a very easy solution  Simply delete the npm and npm cache folder from your pc  Reinstall it again  but the mistake that many of us make is not installing npm globally So   npm i -g npm   And then  install nodemon globally   npm i -g nodemon   Now nodemon works globally  even without using the command   npx nodemon  lt yourfilename gt  js
