Here is what worked for me: In packages.json, add the dependency

“angular-in-memory-web-api”: “^0.2.0”

then, npm install and npm start. Note that I used angular-cli to build the app, so there is no systemjs… That’s all I had to do, specifically there were no changes in the tutorial code.

Also with'angular2-in-memory-web-api': '0.0.9' is working well. I changed 'angular2-in-memory-web-api': { defaultExtension: 'js' } to 'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' }and for me is working fine.

the fix in my end is making sure that HttpModule is added first before InMemoryWebApiModule

  imports: [
    HttpModule, // sequence is important define HttpModule first before InMemory

I also stumbled upon this issue coming from angular-cli. You should fix this either in angular-cli or in the documentation.

Like @wilee53, adding "angular-in-memory-web-api": "^0.2.0" in package.json fix the problem.

Thanks for the answer.

I also used angular-cli to create the project in which I followed the tutorial, hence the issue.

I think I understand why this issue was closed: the official tutorial probably assumes the user has started the project manually and not from the angular-cli.

However, the previous chapter in the official Angular website is about angular-cli, so I’m sure I won’t be the last one having this issue.

I suggest the following paragraph to be added to the tutorial: “If you used angular-cli to create the project, you need to execute the following command: npm install angular-in-memory-web-api --save”

What do you think?

If it makes sense, could it be added?
