Have you already done a "npm update"? It looks like you have installed 0.1.3 version – Carlos

Update to Node.JS v6.9+ and NPM v3.x, and update reflect-metadata to 0.1.3 as noted.

The error you describe occurs, because although you installed the package angular2-in-memory-web-api, which specifies that it needs the a certain version of another package to function properly. While said package is already installed through your angular installation, it is not the version the package specified.

With npm update you can try to update all packages to their most current version, including the bad dependency.
