Node and npm too slow to start after install of macOS Mojave

Question

Actually, before macOS Mojave, node/npm would start immediately, and then depending on the task would take their time (10-20 seconds to finish ng start ).

After upgrading to macOS Mojave, it takes 30-45 seconds to start the process, then 10-20 seconds to ng serve.

The only change was upgrading to macOS Mojave

Any ideas?

Answer 1

I was facing the same issue...

Again Issue was not just related to Angular or React project... All the nodejs based CLI got slower after macOS Mojave update.

I had nvm to manage my node version so install LTS again with nvm install --lts and npm start and ng start starts working normally ...

If you do not have nvm just remove nodejs and reinstall again

Answer 2

Try to reinstall node using node version manager. https://github.com/creationix/nvm

Answer 3

I had the same issue but with different programming languages. The issue appears for some network related things, eg slows down tests.

Could you please try the following:

• ensure that localhost is present in /etc/hosts
• add your mac hostname to /etc/hosts as "127.0.0.1 yourhostname"

By the end it should look like

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1 localhost
127.0.0.1 yourhostname
