Failed to write error when installing intl extension on Os x El Capitan

Question

I'm trying to install intl extension on Os x El Capitan. Every time i run sudo pecl install intl, i'm getting following error on the last step. I don't know why the copy operation failed. Is it a bug or am i missing something?

Any help is really appreciated!

Note: I have installed autoconf and icu4c correctly.

Build complete.
Don't forget to run 'make test'.

It sounds like it's related to the new 'System Integrity Protection' lockdown of /usr. See here: #32893556 – Phototransistor

I disabled 'System Integrity Protection' and problem solved. Thanks @DanWillis. – Odisodium

Answer 1

I had this same issue while trying to install intl.

Had to disable the System Integrity Protection like Dan Willis suggested.

1. Restart your computer.

2. When the screen goes black hold down command+r until you boot into the Recovery. You will see the OS X Utilities menu.

3. Next open Terminal. Then enter the following command.

   csrutil disable

Make sure to write it down so you remember it.

4. Restart your mac, let it start up normally.

5. Open Terminal again and install INTL again

   sudo pecl install intl

It will now complete the installation.
