Linuxbrew: "Package bash-completion was not found..." at command prompt.

[villimagg]

I'm prompted with this error message when I open terminal in Fedora 20:

"Package bash-completion was not found in the pkg-config search path.
Perhaps you should add the directory containing `bash-completion.pc'
to the PKG_CONFIG_PATH environment variable
No package 'bash-completion' found
bash: /yum: No such file or directory"

I have isolated the problem and it is most definitely connected to Linuxbrew.

Please tell me what ever information is required for solving this.

Thank you.

Is the formula bash-completion installed? If you remove the package bash-completion, does the error go away?

brew remove bash-completion

[villimagg]

The formula bash-completion was installed and removing it didn't fix it. Other formulas installed were autoconf, libyaml, pkg-config, and ruby-build. I removed all of them an rebooted and then the error message disappeared.

Will try installing pkg-config again and see what happens. If it is connected to that formula. It might be a bug with pkg-config since in the error message "Package bash-completion was not found in the pkg-config search path."

[villimagg]

I can confirm that the bug is related to the formula pkg-config. Reinstalling pkg-config and rebooting resulted in the same error message as before when I open the terminal. Only now the formula bash-completion was not installed as it was before although the same error message appeared back then when bash-completion was installed.

[sjackman]

That's pretty strange. Can you post your .bashrc and .bash_profile in a gist?

[villimagg]

Here is the gist: https://gist.github.com/villimagg/8293858

Ok.. so pkg-config came as a dependency with ruby-build which I installed along with rbenv. bash-completion came as a dependency with rbenv.

The original error message say's:

"Package bash-completion was not found in the pkg-config search path.
Perhaps you should add the directory containing `bash-completion.pc'
to the PKG_CONFIG_PATH environment variable
No package 'bash-completion' found
bash: /yum: No such file or directory"

Which must mean that anyone can add the path to bash-completion to the PKG_CONFIG_PATH environment variable within pkg-config ?

And now I've been searching where I can add the bash-completion path to the PKG_CONFIG_PATH and I have no idea.

[sjackman]

I don't see that rbenv has any build dependencies.

➜  ~  brew deps rbenv     
➜  ~  brew deps ruby-build
autoconf
openssl
pkg-config
➜  ~  

[villimagg]

Thanks for the link. I'll take a look at it.

Here is the output when running brew install rbenv ruby-build:

pkg-config comes as a dependency for ruby-build and then after running brew install rbenv ruby-build my terminal starts complaining about bash-completion.

Unable to reproduce.

I'm having the same issue. I needed to install pkg-config for another package (it is a depend of makedepend which was required for openssl) and have been getting the same error:

Package bash-completion was not found in the pkg-config search path.
Perhaps you should add the directory containing `bash-completion.pc'
to the PKG_CONFIG_PATH environment variable
No package 'bash-completion' found
bash: /yum: No such file or directory

[sjackman]

@gawbul Do you have bash-completion installed? brew list --versions bash-completion

[gawbul]

@sjackman tried it both with and without bash-completion installed.

When installed I get:

$ brew list --versions bash-completion
bash-completion 1.3

[gawbul]

Doing a find ~/ -name "bash-completion.pc" doesn't find the bash-completion.pc file?

[sjackman]

bash-completion doesn't appear to install bash-completion.pc.

❯❯❯ brew list bash-completion |grep -c 'pc$'
0

[sjackman]

I bet that your .bashrc or .bash_profile uses pkg-config to set up bash-completion and that fails if the PKG_CONFIG_PATH is changed to not include that search directory. Linuxbrew does change the PKG_CONFIG_PATH when it's building software. I would recommend hard-coding the path to bash-completion.pc in your BASH startup file.

[gawbul]

Hard coded into .bashrc and that worked, thanks 👍

[sjackman]

Grand. Thanks for the feedback.

[blitzter]

Hi @gawbul ,
I'm getting the exact same issue in my Fedora 22 machine.
What exactly was added to .bashrc as bash-completion.pc is not really there.

Can you please provide the addition to .bashrc so I and possibly others can fix the issue?

[gawbul]

Hi @blitzter. I did the following:

[smoss@bioserva ~]$ locate bash-completion.pc
/usr/share/pkgconfig/bash-completion.pc

So I added export PKG_CONFIG_PATH=/usr/share/pkgconfig:$PKG_CONFIG_PATH to my .bashrc.

[blitzter]

Thanks @gawbul ,
The error message is gone if the line mentioned above is added on top of .bashrc (before /etc/bashrc processing).

[gawbul]

Sorry, @blitzter, yes, I added it to the top of my .bashrc!

[Osndok]

I've started getting this message too (in a VM that is also using Fedora 20).

I understand where the message is being generated, from a stock fedora package ("yum-utils"):

$ grep -n pkg-config /etc/bash_completion.d/yum-utils.bash 
2:type -t _yum >/dev/null || . $(pkg-config --variable=completionsdir bash-completion)/yum

As I understand it, this message is "switched on" when a linuxbrew "pkg-config" binary is preferentially used over (earlier in the PATH than) the stock one by the yum-utils package in fedora.

So, then... ignoring the workaround for a moment... isn't the root issue either:

1. that linuxbrew pkg-config should be bottled (if it does not work for in the more general system-wide use), or
2. that linuxbrew pkg-config should also loop-in system package definitions by default (or as a fallback? if it is intended to replace the stock pkg-config)

?

[sjackman]

that linuxbrew pkg-config should be bottled

I think perhaps you mean keg_only. You can brew unlink pkg-config if you like.

that linuxbrew pkg-config should also loop-in system package definitions by default

We explicitly do not include system pkg-config files to avoid using system host libraries unintended, which may conflict with Linuxbrew libraries. You can modify your PKG_CONFIG_PATH to use both.

Neither of these workarounds is a clear win as both of these solutions have their own downsides.
