Failed to build zopfli (was: Installation failed on Ubuntu 16.04LTS with Node 7.0.0 and npm 3.10.9)

[koalabi]

Please provide us with the following information:

OS?

Ubuntu 16.04LTS

Versions.

ng claims to be installed but outputs undefined to 'ng --version' (node --version : 7.0.0)

Repro steps.

"ng new" fails silently: no error message but no file (nor directory) creation.

The log given by the failure.

(No log: absolutely no output, despite 'which ng' yielding '/usr/local/bin/ng' :-()

Mention any other details that might be useful.

Installation emitted several warning (deprecations) and errors when attempting to compile native extensions (maybe due to the unavoidable sudo under Ubuntu for "npm install ... -g"?). Problem is compounded by the fact that reinstalling or uninstalling/reinstalling does not seem to trigger compilation attempts again; so I'm stuck.

Output from very first installation attached below:
ng-cli.install.log-1.txt

---

Thanks! We'll be in touch soon.

UPDATE: short of anything better, I followed the procedure described for manual upgrades of beta (uninstall, clean cache, reinstall), while being root (sudo bash). Now, ng seems to be installed and at least partially running (will check further) but the build errors for native extensions remain (see attached file for details).

The native extension build errors can be safely ignored. As long as npm install -g angular-cli does not exit with an error code, it should be installed correctly. Any node-gyp or node-pre-gyp errors are the result of optional installs (at least usually).

Sudo should be avoided, see here https://docs.npmjs.com/getting-started/fixing-npm-permissions. That was probably the reason for your errors from the start.

OK, noted. Thanks to both :-)

(Duplicating my comment on #3214)

For those who are still wondering...

The issue in most cases is that the node-zopfil package needs to be locally compiled on most systems, and it requires C++11 compilation options.

For those of you on an Ubuntu/Debian distro, this means using a g++ compiler with a version 5.1 or later. If you wish to upgrade the default compiler, follow these steps:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5.1 g++-5.1
sudo rm /bin/usr/g++
sudo ln -s /usr/bin/g++-5 /usr/bin/g++

You will still get some compiler warnings about unused functions, but the overall NPM setup and installation should proceed without error.
