Upgrade to fsevent v2 - Node 13 support

npm WARN deprecated fsevents@1.2.9: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

Using node version 13 it doesn't even build (I'm on Catalina)

I'm hoping to offload this to sane amasad/sane#130 (comment), but we might need to update here

fsevents v2 also unblocks local Node v12 on OSX, so this change would be super beneficial.

[SimenB]

it actually seems pretty trivial to upgrade

[SimenB]

@milesj you can use watchman which is faster with Jest to be unblocked

[milesj]

The issue was jest-haste-map was installing fsevents v1, which blocked usage of Node v12 on OSX since it can't compile the binaries. I'll hold out until the fsevents v2 lands in the next release.

hi
I using npm in laravel can you help me this error?

[aaalsubaie]

the warning still exists!
jest "24.9.0"
jest-haste-map: "^24.9.0"

I believe this will be fixed by #9215 once a new version of jest-haste-map is released: #9215 (comment)

Update: in the meantime, I was able to fix the problem by running npm i fsevents@latest in my project, which seems to prevent npm from installing the older optional dependency within jest-haste-map/node_modules.

[banerRana]

by running npm i fsevents@latest on windows for solving the following issue
"$ npm install
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2."

led to

"npm ERR! notsup Unsupported platform for fsevents@2.2.1: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
npm ERR! notsup Valid OS: darwin
npm ERR! notsup Valid Arch: any
npm ERR! notsup Actual OS: win32
npm ERR! notsup Actual Arch: x64
"

does fsevents for winows platform does not exist

[SimenB]

You can ignore the warning, fsevents is not used via sane, so the old dep doesn't matter (sane is removed entirely in jest@next)
