Hi.  
First of all, thank you for this great update on node-red.  
After installing node-red 1.2.0, node-red won't start, giving me this error:

internal/modules/cjs/loader.js:548  
throw e;  
^

Error: Package exports for '/usr/local/lib/node\_modules/node-red/node\_modules/async-mutex' do not define a valid '.' target

at Module.\_compile (internal/modules/cjs/loader.js:1063:30) {  
code: 'MODULE\_NOT\_FOUND'

I'm updating from 1.1.3 to 1.2.0 a VM on Debian.  
Node version is v13.1.0  
I reverted to 1.1.3 for now.  
It should be something in the async-mutex module, but it should not crash in this manner.  
Have i missing something?  
Thanks.

What version of node.js are you using?

Looks like a known issue with the 13.x Node.js stream - a stream we don't support as it isn't a stable release.

Once you update nodejs you will have to re-install node-red and go to your .node-red folder and run  
`npm rebuild`

Those steps are always required right? For any update of node.js outside of the official script. Suspect so... time to update my notes!

Yes.  
In fact whether you need the rebuild does depend on which nodes are installed, many nodes don't have a build step, but safest just to run it.  
The script does the rebuild automatically.
