Steps to reproduce the problem
If you have hosted this on ubuntu 16.04 with a code that is pulled from your bitbucket (A) , it may not work. but it works when we create a new project.

What is the expected behavior?

The app should strart running in the localserver:1337 as everytime it does.

Suggested solutions
While researching, people are suggesting this is due to the new node version node-inspector/node-inspector#1044

Few people ask to delete node_modules directory and package.json. it doesn't work

2. but if i see the problem is with lodash module, so i deleted the folder, removed from package folder. And tried strapi start ( am not sure whether it is stupid, then i got node module not found, so i installed fresh of Lodash and again the same issue.

And i got this npm audit as well, in case it helps

In your generated app you can run:

npm i it install all node modules in your project, admin and plugins
npm run setup --plugins it build admin and all plugins

[jkbaseer]

Thanks Man @ntloi95

Yes, i went to do it again.

@jkbaseer did you install the strapi package globally?

If no, you can't use the strapi command (as your system isn't aware of the location)

There are two places the strapi package is "kept":

1. In your global node_modules folder to be used as an executable IE strapi start
2. In your project's node_modules/package.json for use by strapi

The reason for the split is, it is possible you may not need the global CLI based tool while running in production if you are using npm start server.js

Please run npm i -g strapi@alpha to use strapi start globally (or any of the CLI based commands like generate)

[derrickmehaffy]

I'm marking this issue as closed for now, please update if this didn't fix the issue and we can re-open it.

[jkbaseer]

Hey Guys, I would request to open up this issue because i tried running commands like

1. installing strapi alpha on the global using npm i -g strapi@alpha

2. root@ed-api-v1:~/ed/ed-api# ls
   README.md admin api config favicon.ico node_modules package.json plugins public server.js

root@ed-api-v1:~/ed/ed-api# strapi start

it doesn't seem to help.

@Aurelsicoko @lauriejim maybe you can assist here. I think he is using Node Version Manager (NVM) which I believe is causing the issue.

[Aurelsicoko]

Did you try to delete the package-lock.json file?

[thkdog]

Did you try to delete the package-lock.json file?

I have solved the problem, you can fixed it in 2 ways:
1.

npm install --unsafe-perm

npm i
npm run postinstall

Check this related issue: npm WARN cannot run in wd node-gyp

Which causing the problem is the node_modules in plugins are not installed.
When using npm i in dockerfile, the postinstall script won't be excuted, as below:

npm WARN lifecycle website-service@0.1.0~postinstall: cannot run in wd website-service@0.1.0 node node_modules/strapi/lib/utils/post-install.js (wd=/usr/src/app)

So you have to execute it manually or using --unsafe-perm options.
