1. Mention any other details that might be useful.
   Commenting out the line 25 on angular-cli/bin/ng makes everything work again.
   This with the check Version.assertPostWebpackVersion(), was added on commit 21003b1 .

@Aorewen Simplest workaround to continue working in your project is comment line 25 of node_modules/angular-cli/bin/ng :
// Version.assertPostWebpackVersion();
Until it is fixed properly.

I just commented out line 25 on angular-cli/bin/ng .
but now ng hangs if I call ng --help
a new line is displayed and I can enter any text but n nothing happens.
I quit the call with ^C.

I do not know if this has to do anything with this nam error message I got after installing angular-cli:

peer dep missing: webpack@1.x.x || 2.x.x, required by string-replace-loader@1.0.3

In the meanwhile I installed web pack:
npm ls webpack -g
/usr/local/lib
└── webpack@1.13.2

But I still get this error:
npm ls angular-cli
angular-cli@1.0.0-beta.14 /usr/local/lib/node_modules/angular-cli
└── UNMET PEER DEPENDENCY webpack@2.1.0-beta.22

Installed web pack@2.1.0-beta.22 but now I get the "old" message:
npm ls angular-cli
....
npm ERR! peer dep missing: webpack@1.x.x || 2.x.x, required by string-replace-loader@1.0.3

[alexverdaguer]

Updated node to v6.6.0 and now it works !

[ValeryVS]

I fix this for node 6.5.0 with #2178

[JelF]

Persisted in v6.6.0 for me
