The CLI will install correctly and is not a blocker, but it will throw those warnings and show an error stack for fsevents installation which is a dev dependency and shouldn't affect the CLI workflows.
We're looking into how we can mitigate these warnings and the error stack.

I had this issue when my node was installed using Homebrew on my mac (and hence the need to use sudo for npm install -g).

I no longer had this error after I switched to nvm.

Approximate procedure:

• note the global npm installs using 'npm list -g --depth=0'
• uninstall all the globally installed packages, for example, npm remove -g <package> (or probably could have just nuked the /usr/local/lib/node_modules directory)
• uninstall node usingbrew uninstall node
• install nvm (for example, curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash)
• for some reason, I had to copy the nvm content from ~/.bashrc into ~/.bash_profile to get nvm working. First try next step without doing this.
• install node via nvm (for example, nvm install --lts)
• and just for fun, upgrade npm using npm install -g npm (note sudo not required)
• reinstall all the global installs that you noted (for example, npm install -g @aws-amplify/cli)

note: sudo no longer required for global npm installs.

Hope this helps.

FYI. I hit a similar error on another package (not amplify-cli), which required switch from node 10 to node 8. Seems any library that uses fsevents needs to have a specific matching version of node depending on the fsevents version.

I also saw npm install -D fsevents@latest on another thread which helped some folks out.

THANK YOU @leantide !
I've spent days trying to get @aws-amplify/cli installed the past few days, to no avail ... until I tried your solution.

[kaustavghosh06]

As @leantide mentioned above these warnings are tied to a specific version of node + the fsevents pacakge. This in no way affects the installation and usage of the CLI.

[GerbenRampaart]

The procedure of @leantide worked for me. Basically getting rid of node completely through brew but also removing it from /usr/local/bin/node and /usr/local/bin/node_modules and THEN SOLELY relying on nvm installed through curl as leantide details worked
