Brew requires linking before installing packages and never works #1519

Closed dannykopping closed 7 years ago

dannykopping commented 7 years ago

Bug reports:

The only step that resolves the issue is removing the affected linked packages and installing the desired package.

For example:

brew install php56           
Updating Homebrew...
==> Installing php56 from homebrew/php
Error: You must `brew link jpeg unixodbc` before homebrew/php/php56 can be installed

To help us debug this issue can you explain:

@dannykopping any update here?

dannykopping commented 7 years ago

I think this should be pretty illustrative:

infomaniac $ brew install gprof2dot
Error: You must `brew link libpng` before gprof2dot can be installed
infomaniac $ brew link libpng
Linking /usr/local/Cellar/libpng/1.6.26... 4 symlinks created
infomaniac $ brew install gprof2dot
Error: You must `brew link libpng` before gprof2dot can be installed
dannykopping commented 7 years ago

Even though this package does not depend on libpng:

$ brew info gprof2dot
gprof2dot: stable 2016.10.13 (bottled), HEAD
Convert the output from many profilers into a Graphviz dot graph.
https://github.com/jrfonseca/gprof2dot
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/gprof2dot.rb
==> Dependencies
Recommended: graphviz ✘
==> Options
--without-graphviz
        Build without graphviz support
--HEAD
        Install HEAD version
ilovezfs commented 7 years ago

OK, so first off, it does depend on libpng because it depends on graphviz, and graphviz depends on libpng. The question is what's wrong with your libpng. Can you post the output of

find /usr/local/Cellar/libpng
ls -l /usr/local/opt/libpng
ls -l /usr/local/var/homebrew/linked/libpng
dannykopping commented 7 years ago

Sorry, my bad

find /usr/local/Cellar/libpng

brew uninstall libpng brew prune brew install libpng

dannykopping commented 7 years ago

That does work, but it doesn't really address the underlying issue?

In my original question, it was a different package with the same linkage issue, and yes uninstalling the problematic package does resolve the issue... but this is happening with every package I try to install.

ilovezfs commented 7 years ago

Can you try

brew list | while read f; do brew unlink $f; brew link $f; done
dannykopping commented 7 years ago

Tried that, gives a bunch of errors:

$ brew list | while read f; do brew unlink $f; brew link $f; done

  brew unlink ansible

  brew link --overwrite ansible

  brew link --overwrite --dry-run ansible
ilovezfs commented 7 years ago

Try first doing

sudo chown -R $(whoami) /usr/local/*

and then 

brew list | while read f; do brew unlink $f; brew link $f; done
dannykopping commented 7 years ago

Have done that too, but will try again

dannykopping commented 7 years ago

Exactly the same result...

$ sudo chown -R $(whoami) /usr/local/*

ilovezfs commented 7 years ago

OK, good.

brew list | while read f; do brew unlink $f; done
brew prune
brew list | while read f; do brew link --overwrite $f; done
MikeMcQuaid commented 7 years ago

You perhaps hit an old migration bug that resulted in bad linkage. @ilovezfs's fix will resolve that.

dannykopping commented 7 years ago

Thanks, i'll try this out later 👍

dannykopping commented 7 years ago

Ran the above and i get the same issue:

infomaniac:~ $ brew install gprof2dot

infomaniac:~ $ brew link libpng

@dannykopping What's the output of brew doctor now and your brew config?

@dannykopping can you come on IRC please?

machomebrew on freenode (https://www.irccloud.com/#!/ircs://irc.freenode.net:6697/%23machomebrew)

ilovezfs commented 7 years ago

Any update here?

That does work, but it doesn't really address the underlying issue?

I'm not sure there is an underlying issue here. You've hit what appears to be some sort of corner case with the migration that occurred two months ago. No one else is reporting this, and you've indicated there is in fact a viable path toward fixing things.

We may need to punt at this point.

dannykopping commented 7 years ago

Sorry, i should have been more clear... I'm experiencing the same issue in that i can't install a package, but at least the linking appears to work the first time i run the command.

But I'm still in that loop of link, install, link, install like before.

ilovezfs commented 7 years ago

can you post

find /usr/local -ls

in a gist please?

dannykopping commented 7 years ago

Can you be more specific about which folders you want to inspect? The output is too big for a gist

ilovezfs commented 7 years ago

You can try

find -E /usr/local -not -regex "^/usr/local/(Cellar|bin|etc|include|lib|sbin|share)/.*" -ls |grep -v -E '\.git\/'|grep -v Taps|grep -v portable-ruby|grep -v MacGPG|grep -v Caskroom

OK, that may be a problem. Why is this on a different volume?

dannykopping commented 7 years ago

I keep my code on a separate case-sensitive partition

ilovezfs commented 7 years ago

Yup, having that on the separate volume is the cause of your problem. Reproduced:

iMac-TMP:~ joe$ brew uninstall gawk
Uninstalling /usr/local/Cellar/gawk/4.1.4_1... (64 files, 2.8M)
iMac-TMP:~ joe$ brew install gawk
Error: You must `brew link gmp mpfr` before gawk can be installed
dannykopping commented 7 years ago

Interesting - so when did brew start using the /usr/local/var/ directory? I've had this configuration from the beginning and it's worked perfectly.

ilovezfs commented 7 years ago

The migration that Mike mentioned above moved some things from /usr/local/Library to /usr/local/var/homebrew.

You can configure this in a way that works, though:

iMac-TMP:~ joe$ diskutil unmount /Volumes/ramdisk/
Volume ramdisk on disk2s1 unmounted
iMac-TMP:~ joe$ sudo rm /usr/local/var
iMac-TMP:~ joe$ sudo mkdir /usr/local/var

There are probably other ways to get it working properly too, but I'd just recommend keeping your code mounted somewhere other than /usr/local/var.

ilovezfs commented 7 years ago

@dannykopping It would be great if you'd like to open a pull request for a doctor check that can detect this problem so that it doesn't cause a mystery in the future if it happens again to someone else :)

dannykopping commented 7 years ago

Hhmm, unfortunately that's not practical at this point. Is there something I can hack to change the base directory?

ilovezfs commented 7 years ago

Yeah, you should be able to set these environment variables

# Where we store symlinks to currently linked kegs
HOMEBREW_LINKED_KEGS = HOMEBREW_PREFIX/"var/homebrew/linked"

# Where we store symlinks to currently version-pinned kegs
HOMEBREW_PINNED_KEGS = HOMEBREW_PREFIX/"var/homebrew/pinned"

# Where we store lock files
HOMEBREW_LOCK_DIR = HOMEBREW_PREFIX/"var/homebrew/locks"

https://github.com/Homebrew/brew/blob/master/Library/Homebrew/config.rb#L20-L27

dannykopping commented 7 years ago

Do i set them as actual env variables in my ZSH config or hack this file? I tried setting them this way and brew is not respecting that

ilovezfs commented 7 years ago

Yup, you're right. It looks like it cannot be overridden with an environment variable.

dannykopping commented 7 years ago

Even tried setting the HOMEBREW_PREFIX env variable and that's not being respected either.

$ echo $HOMEBREW_PREFIX
/usr/homebrew
$ brew link php56 --verbose
....

ilovezfs commented 7 years ago

Prefix is definitely respected. So something is wrong with how you're doing that.

ilovezfs commented 7 years ago

It's most likely because you're trying to use the stuff that's already installed in the old prefix, which isn't going to work. You'd have to uninstall the formula first, and then reinstall it. Note that if you move the prefix, you're going to end up only being able to use the relocatable bottles and having to build everything else from source.

dannykopping commented 7 years ago

OK, i'll have to play around with this after Black Friday :) too risky right now. I'll let you guys know what happens - thanks!

ilovezfs commented 7 years ago

You're welcome :)

MikeMcQuaid commented 7 years ago

Prefix is definitely respected

It isn't, actually 😉.

ilovezfs commented 7 years ago

It isn't, actually :wink:

meaning?

MikeMcQuaid commented 7 years ago

You can't set HOMEBREW_PREFIX manually to change the prefix (or HOMEBREW_REPOSITORY).

ilovezfs commented 7 years ago

Ah, right, it tracks the brew file itself. Thank you for correcting me.

dannykopping commented 7 years ago

So how can I get around this? Fork the brew repo, edit the upstream in the git config and edit the config.rb?

MikeMcQuaid commented 7 years ago

You need to install Homebrew into a different location or keep var on the same volume (recommended so you can keep using bottles/binary packages).

dannykopping commented 7 years ago

a) "You need to install Homebrew into a different location" - is there a guide for this? b) "keep var on the same volume (recommended so you can keep using bottles/binary packages)" - the whole of /usr/local/var, or just /usr/local/var/homebrew?

ilovezfs commented 7 years ago

@dannykopping you can probably just use symlinks in /usr/local/var to all the top level directories in /Volumes/CSP/usr/local/var except for /usr/local/var/homebrew.
