How do I find out which version of angular-cli a version of nodejs support?

Question

I'm using nodejs v8.8.1 and angular-cli v6.0.8 and I got this error:

You are running version v8.8.1 of Node.js, which is not supported by Angular CLI v6. The official Node.js version that is supported is 8.9 and greater.

If I'm going to install a different version of angular-cli, how can I check which version is supported by nodejs v8.8.1? I cannot do it the other way around since I have to use nodejs v8.8.1.

TL;DR: If you can't use any other version of node, it looks like you should use v5.

What I did was clone the angular-cli repo and then ran:

git log --oneline -p -L 48,48:package.json --diff-filter=m

• --oneline to show only the short log of the commit
• -p to generate a patch listing
• -L 48,48:package.json which is the current line the node version is set on in package.json as of commit 7924e0a
• --diff-filter=m to show only file modification (although that probably doesn't matter here)

which produced the log listing below. This shows every time the explicit node version requirement changed in the package.json engine properties.

As you can see it was changed 3 times:

• c38b5c09 it was explicitly set to node >= 4.1.0
• 08af5d54 it was unchanged, but an explicit npm version was set (npm >=3.0.0)
• 0a1f19ff it was set to node >= 6.9.0
• 29338bca it was set to node >= 8.9.0

So, from that, you can assume that you can use any version of Angular from before that commit should work. That particular commit is for the v6.0.0-beta3. So I would say major version v5.
