react-router peerDependencies error

Question

I'm trying to install react-router but I get the following error.

$ npm install react-router
npm WARN peerDependencies The peer dependency [email protected] included from react-router will no
npm WARN peerDependencies longer be automatically installed to fulfill the peerDependency
npm WARN peerDependencies in npm 3+. Your application will need to depend on it explicitly.

The package.json for react in node-modules shows that I use:

"version": "0.14.0-rc1",

Should I install an earlier version? It seems that 0.13.x might be a better supported version?

If that is the case, how can I install without messing up my current project?

After using

npm install npm -g

I typed npm -v and saw that the version in my project is still 2.11.13. I figured that it might be a local version of NPM so I typed:

npm install npm

hoping to get the latest version updated locally, but still got 2.11.13 when I checked for the version.

comp-asus XXX64 /c/ReactApps/goodRouter/goodrouter (master)
$ npm -v
2.11.3

When checking globally I can see that it is updated:

$ npm list -g --depth=0

    ├── [email protected] invalid

    └── [email protected]

But how do I use the global version in the project?

So the problem persists but I do believe you put me on the right track.

$ where npm
C:\Program Files\nodejs\npm
C:\Program Files\nodejs\npm.cmd
C:\Users\Roger\AppData\Roaming\npm\npm
C:\Users\Roger\AppData\Roaming\npm\npm.cmd

So I should delete one of these?

This is one of the major issues solved in npm@3. See https://github.com/npm/npm/issues/6565 for details.

Updating npm is the right thing to do:

$ npm install npm -g

Thank you! Please see update if you can. I do not have enough rep to +1 but I do thank you. – RogerDore Oct 07 '15 at 10:46
@RogerDore Are you using some tool for managing Node versions, like `nvm`? – eush77 Oct 07 '15 at 10:52
I am not familiar with Tools for managing Node versions. I will look up nvm right now. – RogerDore Oct 07 '15 at 10:58
@RogerDore No, I didn't mean that… There is another `npm` in your `$PATH` and `nvm` can be a source of this so I asked. You need to disable the other `npm` (move it or make it non-executable). – eush77 Oct 07 '15 at 11:05
@RogerDore Can you find that location with `where npm` or other suggestions from http://stackoverflow.com/questions/304319/? – eush77 Oct 07 '15 at 11:08
Ok! Im not sure of wath I am doing now but it seems that there are two: Made a new update. – RogerDore Oct 07 '15 at 11:13
@RogerDore So as it seems you are using `[email protected]` from `C:\Program Files\nodejs` but your global install directory is `C:\Users\Roger\AppData\Roaming\npm`. That is why you can't update `npm` easily. Moving or renaming `C:\Program Files\nodejs\npm` (and probably `npm.cmd`, I'm not sure) should fix the problem. – eush77 Oct 07 '15 at 11:23
By changing name as you suggested it now uses 3.3.5. Thank you! – RogerDore Oct 07 '15 at 11:31
