The Windows solution is the same as the Linux sudo answer  Run the npm start  or whatever  as Administrator  I had added a new module to my project  Worked on some machines but on others that were more locked down  not so much  Took a while to figure it out but the new module needed access to  something  that wasn t available without administrator permissions

While working on a WordPress theme  I got the same ELIFECYCLE error with slightly different output    npm ERR  Darwin 14 5 0 npm ERR  argv   usr local Cellar node 7 6 0 bin node    usr local bin npm   install  npm ERR  node v7 6 0 npm ERR  npm  v3 7 3 npm ERR  code ELIFECYCLE npm ERR  foundationsix 1 0 0 postinstall   bower install    gulp build  npm ERR  Exit status 1 npm ERR   npm ERR  Failed at the foundationsix 1 0 0 postinstall script  bower install    gulp build   npm ERR  Make sure you have the latest version of node js and npm installed  npm ERR  If you do  this is most likely a problem with the foundationsix package  npm ERR  not with npm itself  npm ERR  Tell the author that this fails on your system  npm ERR      bower install    gulp build   After trying npm install one more time with the same result  I tried bower install  When that was successful I tried gulp build and that also worked   Everything is working just fine now   No idea why running each command separately worked when  amp  amp  failed but maybe someone else will find this answer useful

I had the same error code when I was running npm run build inside node docker container   Locally it was working while inside a container I had set option to throw error when there is a warning during compilation while locally it wasn t set  So this error can mean anything that is connected with stopping the process being done by NPM

One might think this is because outdated versions of npm and node  but it s not the case   Just as Pierre Inglebert says  if you look into the source you can see that End of lifecycle means the program unexpectedly stopped  This can have various reasons  So it s not a syntax error and not an expected exception error   The error appeared to me when a different tool was already using the http port  3000  defined in my node scripts  When you run your node app on port 80  make sure you have stopped Apache webserver  as an example
