Installation failed with LTS Node version12.16.1

[vkuehn]

Description

Reproduction Steps

following the https://github.com/eclipse-theia/theia/blob/master/doc/Developing.md#quick-start guid fails with

error @theia/[email protected]: The engine "node" is incompatible with this module. Expected version ">=10.11.0 <12". Got "12.16.1"

OS and Theia version:
OS is Ubuntu 18.04
Node Version is 12.16.1 (LTS)
Git cloned latest theia version

Diagnostics:
no further analytics requiered thought you want see the problem with old docker images

error @theia/[email protected]: The engine "node" is incompatible with this module. Expected version ">=10.11.0 <12". Got "12.16.1"

Yeah, an error says that it is not supported. Please use Node 10 instead.

[vkuehn]

ok will do in a docker Image, actually I would hope for a release soon for the latest Node JS version...No ?

[akosyakov]

We align with Node.js version of currently used Electron as minimum. Till we don't upgrade to new version of Electron I don't think active committers will invest into supporting latest Node.js. Someone from the community could invest time and look how to include Node.js 12 in supported range without breaking the minimal version if it is critical for them.

[akosyakov]

VS Code extensions are allowed to use Node.js 12 API. It can become a problem if some will do.

[a1994846931931]

We should support Node.js 12.

@kittaakos so that issue can be closed ?

so that issue can be closed ?

No, not yet. Here is the PR: #7968

[adamretter]

This is great, thank you!

Any chance of a release so that we can test it?

Any chance of a release so that we can test it?

I think we have a release scheduled this Thursday, or you can use the next version.

[adamretter]

@kittaakos We did some experimentation with the last release version on Node 10 and Node 12. We found that it would build already for Node12 on Linux, but not on Mac.

However, regardless of the Node version we found that to get it building with Python3 (as opposed to Python 2) we had to force it to use the latest npm-gyp. This was especially relevant for macOS Catalina, see - https://github.com/nodejs/node-gyp/blob/master/macOS_Catalina.md

To do that we had to add a resolutions section to our package.json for yarn:

"resolutions": {
   "node-gyp": "^3.8.0",
   "node-gyp": "^7.0.0"
},

Before you do the next release, I think it might make sense for @theia/electron to also move to the latest node-gyp dependency. What do you think?

You can see our various Linux/macOS Node10/12 Python2/3 builds here: https://travis-ci.com/github/evolvedbinary/fusion-studio-extension/builds/176406238

[kittaakos]

but not on Mac.

I haven't had a build issue on macOS. What's the error? Also, please share a repo, or at least a package.json + yarn.lock combo.

get it building with Python3

We still need Python2 as far as I know.

he latest node-gyp dependency. What do you think?

Sounds good to me, but I won't have the time to change anything wrt the node-gyp version. Are you willing to contribute?

---

I think we have a release scheduled this Thursday, or you can use the next version.

We have the next release on 30.7, next week.

[kittaakos]

Here is another issue related to the current node-gyp version: #8065 (comment)

[adamretter]

@kittaakos Further info:

please share a repo, or at least a package.json + yarn.lock combo.

Sure, it was linked vai Travis, but you can find it directly here: https://github.com/evolvedbinary/fusion-studio-extension/tree/ci-test-adam

I haven't had a build issue on macOS. What's the error? Also, please share a repo, or at least a package.json + yarn.lock combo.

It is as in the Travis CI results page I linked to. This is the error when trying to build against Node12 on macOS (both 10.13 and 10.15):

We still need Python2 as far as I know.

As per my Travis CI results - it builds fine with Python 3, but ONLY if you update to the latest node-gyp.

Are you willing to contribute?

Absolutely. What's the process? Just send a PR? do you have automated CI etc to check it for me?

@adamretter, I have started a macOS build with Node.js: https://travis-ci.com/github/eclipse-theia/theia/jobs/363327516
We can build the project on macOS with Node.js 12.x.

To do that we had to add a resolutions section to our package.json for yarn:

"resolutions": {

Adding resolutions is the preferred way. Please do not consider it as a hack. We do this in downstream projects, in the theia-apps repo, we even do it for theia.

As per my Travis CI results - it builds fine with Python 3, but ONLY if you update to the latest node-gyp.

So if I understood you correctly; your goal is to be able to build with Python3 on macOS. For that, we need to increase the node-gyp version. Please keep in mind, we cannot drop Python2 even if can build Python3 after your change.

Absolutely.

Great.

What's the process?

Just send a PR?

Yes.

do you have automated CI etc to check it for me?

Yes.

I want to build with Python 2 and 3 on all platforms. We have that working here by updating the node-gyp version.
I will try and send a PR to do that in Theia itself.

I also want to be able to build for NodeJS 12 as well as NodeJS 10. Using the latest release, i.e. before the PR #7968, my experience is that NodeJS 12 fails on macOS, I will now test with the latest HEAD code.

I will send a separate PR to increase the number of your Travis CI jobs to cover that platform too.

[kittaakos]

Python 2 and 3 on all platforms.

Sounds great!

build for NodeJS 12 as well as NodeJS 10

OK. Note, we will drop Node.js 10.x soon. #8184

I will send a separate PR to increase the number of your Travis CI jobs

Watch out, that might get rejected as we do not want to unnecessarily increase the build time.
