(This is a reminder to myself, and maybe a help for someone else who might be in the same situation as me. The purpose was to be able to lint documentation I’m trying to update for the pip project work.)
This applies to installing “the latest” Python on Mac OS X 10.15.6.
I’ve used this helpful How-TO. Everything worked until the very end where brew couldn’t create a necessary directory:
Permission denied @ dir_s_mkdir - /usr/local/Frameworks
(no idea why!)
==> Summary 🍺 /usr/local/Cellaremail@example.com/1.1.1h: 8,067 files, 18.5MB ==> Installing firstname.lastname@example.org ==> ./configure --prefix=/usr/local/Cellaremail@example.com/3.9.0_1 --enable-ipv6 --datarootdir=/usr/local/Cellarfirstname.lastname@example.org/3.9.0_1/share --datadir ==> make ==> make install PYTHONAPPSDIR=/usr/local/Cellaremail@example.com/3.9.0_1 ==> make frameworkinstallextras PYTHONAPPSDIR=/usr/local/Cellarfirstname.lastname@example.orgemail@example.com Error: An unexpected error occurred during the `brew link` step The formula built, but is not symlinked into /usr/local Permission denied @ dir_s_mkdir - /usr/local/Frameworks Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks
I reran install python and got:
bernard@computer-number-6 ~ % brew install python Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/cask). ==> Updated Casks geekbench Warning: firstname.lastname@example.org 3.9.0_1 is already installed, it's just not linked You can use `brew link email@example.com` to link this version.
The solution was to create the /usr/local/Framworks directory manually:
bernard@computer-number-6 ~ % sudo mkdir /usr/local/Frameworks
Then change the owner and group to mirror other directories (bernard:admin)
bernard@computer-number-6 ~ % sudo chown bernard /usr/local/Frameworks bernard@computer-number-6 ~ % sudo chgrp admin /usr/local/Frameworks bernard@computer-number-6 ~ % ls -la /usr/local/ total 0 drwxr-xr-x 17 root wheel 544 11 Nov 12:01 . drwxr-xr-x@ 11 root wheel 352 12 Dec 2019 .. -rw-r--r-- 1 root wheel 0 18 Sep 2019 .com.apple.installer.keep drwxrwxr-x 3 bernard admin 96 1 Apr 2019 Caskroom drwxrwxr-x 63 bernard admin 2016 11 Nov 11:39 Cellar drwxr-xr-x 2 bernard admin 64 11 Nov 12:01 Frameworks
And finally run the brew link command from above:
bernard@computer-number-6 ~ % brew link firstname.lastname@example.org Linking /usr/local/Cellaremail@example.com/3.9.0_1... 5 symlinks created bernard@computer-number-6 ~ %
And then I could start what I wanted to actually do. 🙂
