I mistakenly ran brew upgrade<\/code> on my macOS Catalina without thinking about how it would impact my production development environment during work, and quickly realized I messed up big time.<\/p>\n\n\n\n

To fix it, install openssl & icu4c, edit the php 5.6 source (see post for details), and reinstall php 5.6 from source to overwrite.<\/p>131 characters<\/cite><\/blockquote><\/figure>\n\n\n\n\n\n\n\n

My production environment has to use PHP 5.6.40 because of some legacy plugins that do not exist, or were not installed with a package manager (e.g. composer) because it didn’t exist at the time, and the business has not decided to invest the time to update all the features to use newer versions…and in some cases there are no newer versions. <\/p>\n\n\n\n

So after updating my environment, I had to make sure I didn’t get put back on PHP 7.4.x, and was still on PHP 5.6. I was, but it was now broken.<\/p>\n\n\n\n

Error Messages<\/h2>\n\n\n\n

The first error message I got when trying to check the PHP version<\/p>\n\n\n\n

tsnMac:~ neotsn$ php -v\ndyld: Library not loaded: \/usr\/local\/opt\/openssl\/lib\/libcrypto.1.0.0.dylib\n  Referenced from: \/usr\/local\/bin\/php\n  Reason: image not found\nAbort trap: 6<\/code><\/pre>\n\n\n\n
This is because macOS has its own SSL library installed, and PHP 5.6 requires OpenSSL…and isn’t compatible with OpenSSL 1.1, which is what got installed in the update.<\/p>\n\n\n\n
After reinstalling OpenSSL 1.0 from a direct package link, I encountered the next message, which was much more difficult to solve, since icu4c<\/code> is covered by macOS Data Integrity Protection.<\/p>\n\n\n\n
dyld: Library not loaded: \/usr\/local\/opt\/icu4c\/lib\/libicui18n.64.dylib\n  Referenced from: \/usr\/local\/Cellar\/php@5.6\/5.6.40\/bin\/php\n  Reason: image not found<\/code><\/pre>\n\n\n\n
The Fixes<\/h2>\n\n\n\n
Thanks to the instructions over in this Github Issue<\/a> from JParkinson1991<\/a>, and various other articles and blogs around the internet I’ve pieced together this solution, but his updated comment provided the majority of the answer.<\/p>\n\n\n\n
Starting over?<\/h3>\n\n\n\n
Obviously you’re going to need Homebrew, which you probably already have if you’re here… but in case you wiped your hard disk (as I did) and have to start over…<\/p>\n\n\n\n
# Install Homebrew\n\/usr\/bin\/ruby -e \"$(curl -fsSL https:\/\/raw.githubusercontent.com\/Homebrew\/install\/master\/install)\"\n\n# Bring in deprecated php versions\nbrew tap exolnet\/homebrew-deprecated<\/code><\/pre>\n\n\n\n
Now you’ll have Homebrew installed and the deprecated PHP versions available to you.<\/p>\n\n\n\n
Update these packages<\/h3>\n\n\n\n
Before you start down the path, make sure the problematic packages (openssl<\/code> and icu4c<\/code>) are at the latest versions (and indeed installed).<\/p>\n\n\n\n
# Make sure these are at the latest versions\nbrew install openssl && brew upgrade openssl\nbrew upgrade icu4c<\/code><\/pre>\n\n\n\n
Patching PHP 5.6<\/h3>\n\n\n\n
Note: This will soon be fixed<\/h4>\n\n\n\n
At the time of this writing, there exists a merge request for the php@5.6 package<\/a> where the following patch will no longer be required. I do not have instructions on what to do once it has been, but presumably this article will never reach your eyeballs if you have the latest version of these eXolnet<\/a> repositories.<\/p>\n\n\n\n
The patch…<\/h4>\n\n\n\n
If the above merge request is still outstanding, then let’s edit the php@5.6<\/code> package…<\/p>\n\n\n\n
# Edit php@5.6 to add a patch \nbrew edit php@5.6<\/code><\/pre>\n\n\n\n
This will open up the edited file in vim (or at least it did for me). So jump to line 45-48. Look for the def install<\/code> around there. Right before that line, insert these lines…<\/p>\n\n\n\n
# At line 45, before the `def install` command, add these lines\npatch do\n  url \"https:\/\/raw.githubusercontent.com\/opencomputeproject\/Rack-Manager\/master\/Contrib-Inspur\/openbmc\/meta-openembedded\/meta-oe\/recipes-devtools\/php\/php\/0001-PHP-5.6-LibSSL-1.1-compatibility.patch\"\n  sha256 \"c9715b544ae249c0e76136dfadd9d282237233459694b9e75d0e3e094ab0c993\"\nend<\/code><\/pre>\n\n\n\n
Save your changes and exit with an esc<\/code> press and a :wq<\/code>.<\/p>\n\n\n\n
Reinstall php@5.6<\/code> from source<\/h4>\n\n\n\n
Now that our package is different from what was downloaded, we need to reinstall it from that source…<\/p>\n\n\n\n
# Reinstall php@5.6 from the edited source\nbrew reinstall --build-from-source php@5.6<\/code><\/pre>\n\n\n\n
This will take a minute or two. When it’s done you should be able to do a php -v<\/code> command to see that there are no more errors and you’re on the correct version.<\/p>\n\n\n\n
Run the checkup<\/h4>\n\n\n\n
Afterward, be sure to run the doctor<\/code> and cleanup<\/code> commands to make sure everything is both good, and clean.<\/p>\n\n\n\n
# Get a checkup\nbrew doctor\nbrew cleanup<\/code><\/pre>\n\n\n\n
Minor Troubleshooting Suggestions<\/h4>\n\n\n\n
If you happen to see you’re not on the right version of PHP after this, you may have to do a forced overwrite link.<\/p>\n\n\n\n
# Only if php -v is not 5.6.x\nbrew link --overwrite --force php@5.6<\/code><\/pre>\n\n\n\n
If you need to have multiple versions of PHP installed, then you’re going to want sphp<\/code> installed.<\/p>\n\n\n\n
# Install sphp to switch versions \ncurl -L https:\/\/gist.githubusercontent.com\/rhukster\/f4c04f1bf59e0b74e335ee5d186a98e2\/raw > \/usr\/local\/bin\/sphp\n# Make it executable\nchmod +x \/usr\/local\/bin\/sphp<\/code><\/pre>\n\n\n\n
Then you’ll be able to switch between them with sphp 5.6<\/code> or any other installed versions using their major\/minor version numbers.<\/p>\n\n\n\n
If you have trouble, you can try dropping a comment here, or onto the linked Github pages where there are better experts than I who may be able to help.<\/p>\n","protected":false},"excerpt":{"rendered":"
