Issues with Node v15

[mathisonian]

Describe the bug
It appears that there may be some incompatibilities with node v15. See #680 and #693.

I'll keep this issue open to track until we've confirmed a fix. For now the recommended solution is to use https://github.com/nvm-sh/nvm to install another version (e.g. v14) and use idyll with that version.

I took a stab at this last night but how do I go about testing npm install idyll would work with the branch I'm working on? I got it passing tests with node 15 by upgrading the react-tooltip library. Related issue here npm/cli#1734, npm install --legacy-peer-deps .. should work too but the dependency issue was patched in react-tooltip 4.0.1. Creating PR showing what I did here #706

If you can run lerna clean && lerna bootstrap in the root of the project with node15 then it should be okay on the dependency side. However I noticed that there is also an issue creating new projects: running idyll create always says that installing dependencies failed, even when it didn't.

A little setup required to test the global command line commands with the local dev version of idyll:

• make a new folder
• run npm init to create a package json
• inside the new package.json add scripts: { "create-idyll-project": "idyll create" }
• inside that folder run yarn link idyll so that the local copy of idyll is available
• run yarn run create-idyll-project to run the idyll create command with the dev version

FYI #707 is main PR now

Thanks for these instructions. I was able to get it running but found an issue with yargs and the commandlineArgs library I introduced in idyll-cli. It was saying command "create" not found . Interestingly when I installed idyll 5.3.4 idyll create was fine but maybe this is just a yarn link thing?

I added a commit fixing that onto #707 since it was pretty small but would you rather I isolate out the commit to something linked to the issue and another branch/PR 386e9cf? Wasn't sure how detailed you like to be about those sorts of things

Thanks @rogerfitz! I merged in #707 to get that idyll create fix in. In general the smaller / more tightly scoped a PR is the quicker I'll be able to review and merge but I am flexible and happy to have fixes submitted in any form.

I'm reopening because of reports that this hasn't been completely resolved. See #723
