2. Sorry. At this time you must use node 6.x. I suspect you are using 7.x based on the number 51 in that error log. That indicates the Node ABI (application binary interface) version of node.

I would suggest either downgrading node or running something like nvm (node version manager) to select a different node version when you run stc.

We will be upgrading our binary modules in a future release.

3. Is this still true that you need Node 6? Because the documentation says you need Node 4.2.1 or newer... Even for STC 2.1.0. See: https://docs.sencha.com/sencha_test/...installing_stc

Otherwise please update the documentation...

I'm getting a similar issue on a Windows Server 2008 R2 machine that can't install anything higher than Node 4.x because of dropped support by Node. My ABI level is 46.

4. I will get the docs updated. STC 2.1.0 should work fine with node 7.

5. Yes, tracking node versions is a bit challenging since we rely on some native modules which are tied to specific major versions. Our next release may resolve this issue by STC not having a dependency on node at all. For now we support Node ABI 48 (6.x) and 51 (7.x) but nothing older or newer.
