node-sass binary not found by new nodejs, can't build due to node-gyp py2.7 dep #795

misyntropy · 2021-05-05T11:53:33Z

Recently tried to install GP again on a new PC, ran into errors with UI duringnpm install:

Trying to retrieve the node-sass binary fails:

This StackOverflow post and GH issue show that its because node-sass 4.12.0 is supported only on nodejs <12
node-sass is required by @angular-devkit/build-angular, whose required version 0.13 constrains node-sass from being updated to any higher version. Not sure if its safe to revise the required version in package.json upward.
npm install then falls back to compiling node-sass 4.12.0 from source, but for this it requires node-gyp 3.8.0 which requires python 2.7. Also see this.

I think, but am not sure, that the fix is to specify the version of nodejs that GridPath UI is compatible with.

The text was updated successfully, but these errors were encountered:

I can't reproduce this. My current setup on Windows is Node.js v14.15, FYI. Are you perhaps using an oldish version of npm? I would suggest upgrading if so since this type of installation issues are often npm-related. On Windows, my npm version is v7.6.3 (I need to upgrade to the latest also).

misyntropy · 2021-05-07T12:23:30Z

This is on node 14.8.0 and npm 6.14.7. Single command to reproduce in this machine was npm install [email protected]. The log is pasted below. Could you try the same? We could then determine if the problem doesn't occur because, for example, a different version is used.

Will try upgrading from npm 6 to npm 7 and see, meanwhile.

@milindsmart, yes, I can reproduce the error by directly trying to install [email protected]. However, note that [email protected] is an optional dependency for @angular-devkit/build-angular, so it does seem to get skipped over during install and is not causing an issue for me with Node.js v14.15, npm v7.6.3, and GridPath v0.9.0. Please let me know if you're still seeing the problem after upgrading node, npm, and gridpath.

misyntropy · 2021-05-14T09:06:49Z

Updating npm to 6.14.13 resulted in success, see below. Node-sass install fails, then the build fails, but the overall install proceeds anyway. Once I verify the built GUI runs and is fully functional, we can close this issue.

Would it be possible to indicate/enforce a minimum node/npm version for GridPath?

npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!

Thanks, @milindsmart. Yes, it makes sense to me to add a brief note on the node and npm version requirements to the README file under the ui folder, probably adding an npm section under the NodeJS section. I can do that as part of the next release (coming soon) and of course you are welcome to pull request something in. (Note that the last time you contributed, your commit didn't seem to be recognized as coming from your GitHub user, probably because of a mismatched email address, so look into this to get the contribution credit on GitHub.)

misyntropy · 2021-05-21T12:24:19Z

Ok confirmed that the GUI built after the npm version upgrade works properly.

Since @angular-devkit/build-angular is the one specifying a version of node-sass that's incompatible with later versions of nodejs, is it possible to bump up the version of @angular-devkit/build-angular in package.json from 0.13.0? I'm not yet comfortable enough with the nodejs ecosystem to contribute though...

Thanks for the tip on the contribution credit, it was indeed a mismatched email address, fixed now.

is it possible to bump up the version of @angular-devkit/build-angular in package.json from 0.13.0

Yes, you could try, but it may create other incompatibility issues. It's a bit of a chore updating dependencies, so reserving some time is usually required for that maintenance work.
