I am using asdf + asdf-erlang as my version manager for Erlang. All seems to be working fine, except that typing erl -man mnesia results in No manual entry for mnesia.
I have installed all dependencies mentioned on the asdf-erlang github page. I have also installed xsltproc and fop. Unfortunately "man" folder located under ~/.asdf/installs/erlang/18.3/lib/erlang/erts-73/ is empty. I haven't found man pages being generated elsewhere.
I was trying to locate build log, but I was not successful with that either.
I am using 64bit Ubuntu 16.10 & 16.04.
OK. I finally managed to resolve the issue:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to ~/.asdf/installs/erlang/<version>/lib/erlang/. After doing so, you should have .~/asdf/installs/erlang/<version>/lib/erlang/man containing man1, man3, man4, man6, man7 (and each of those folders should have some manpages in it).
Repeating steps above for all the versions installed using asdf, allows you to use manpages for specific version of Erlang you are using at the moment.
looks like erlang-manpages are not included in the asdf-erlang since you are using ubuntu i would suggest you add Erlang Solutions repository to your system, call the following commands:
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
then install erlang-manpages:
sudo apt-get install erlang-manpages
you could also install erlang-doc — HTML/PDF documentation
sudo apt-get install erlang-doc
check this page for more information
The man path in #MaciekTalaska 's answer seems not correct, it does not work at all, for erlang 18.3.
After reading ASDF's activate script(), here's one statement:
_KERL_MANPATH_REMOVABLE="$HOME/.asdf/installs/erlang/18.3/lib/erlang/man:$HOME/.asdf/installs/erlang/18.3/man"
Therefore, you just need to:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to $HOME/.asdf/installs/erlang/${version}, but not $HOME/.asdf/installs/erlang/${version}/lib/erlang/ (in fact, there isn't a folder named erlang under lib).

I installed hadoop with sdkman and now I'm trying to install Hive with homebrew but brew wants to install hadoop again because it doesn't know hadoop is already installed on my computer.
I use --ignore-dependencies flag as workaround but it's not a best practice.
Do you know how can I link my hadoop installation done with sdkman to brew?
It is not possible to use a non-Homebrew hadoop with Homebrew hive, see https://docs.brew.sh/Building-Against-Non-Homebrew-Dependencies
To improve quality and reduce variation, Homebrew now exclusively supports using the default formula, as an ordinary dependency, and no longer supports using arbitrary alternatives.
You will have to install Hive manually: https://cwiki.apache.org/confluence/display/hive/gettingstarted#GettingStarted-InstallingHivefromaStableRelease
Installing Hive from a Stable Release
Start by downloading the most recent stable release of Hive from one of the Apache download mirrors (see Hive Releases).
Next you need to unpack the tarball. This will result in the creation of a subdirectory named hive-x.y.z (where x.y.z is the release number):
$ tar -xzvf hive-x.y.z.tar.gz
Set the environment variable HIVE_HOME to point to the installation directory:
$ cd hive-x.y.z
$ export HIVE_HOME={{pwd}}
Finally, add $HIVE_HOME/bin to your PATH:
$ export PATH=$HIVE_HOME/bin:$PATH
Can not get NGINX to install with passenger
Following the steps you are supposed to...
brew install passenger
Then you run the following command...
brew install nginx --with-passenger
But I get:
Error: invalid option: --with-passenger
Could not find any resources about this online, so asking here.
$ brew install nginx --with-passenger
Usage: brew install [options] formula
Install formula.
formula is usually the name of the formula to install, but it can be specified
in several different ways.
-d, --debug If brewing fails, open an interactive
debugging session with access to IRB or a
shell inside the temporary build directory
--env If std is passed, use the standard build
environment instead of superenv.If super
is passed, use superenv even if the formula
specifies the standard build environment.
--ignore-dependencies Skip installing any dependencies of any
kind. If they are not already present, the
formula will probably fail to install.
--only-dependencies Install the dependencies with specified
options but do not install the specified
formula.
--cc Attempt to compile using provided
compiler. compiler should be the name
of the compiler's executable, for instance
gcc-7 for GCC 7. In order to use LLVM's
clang, use llvm_clang. To specify the
Apple-provided clang, use clang. This
parameter will only accept compilers that
are provided by Homebrew or bundled with
macOS. Please do not file issues if you
encounter errors while using this flag.
-s, --build-from-source Compile the specified formula from source
even if a bottle is provided. Dependencies
will still be installed from bottles if
they are available.
--force-bottle Install from a bottle if it exists for the
current or newest version of macOS, even if
it would not normally be used for
installation.
--include-test Install testing dependencies required to
run brew test.
--devel If formula defines it, install the
development version.
--HEAD If formula defines it, install the HEAD
version, aka. master, trunk, unstable.
--fetch-HEAD Fetch the upstream repository to detect if
the HEAD installation of the formula is
outdated. Otherwise, the repository's HEAD
will be checked for updates when a new
stable or development version has been
released.
--keep-tmp Don't delete the temporary files created
during installation.
--build-bottle Prepare the formula for eventual bottling
during installation.
-f, --force Install without checking for previously
installed keg-only or non-migrated
versions.
-v, --verbose Print the verification and postinstall
steps.
--display-times Print install times for each formula at the
end of the run.
-i, --interactive Download and patch formula, then open a
shell. This allows the user to run
./configure --help and otherwise
determine how to turn the software package
into a Homebrew package.
-g, --git Create a Git repository, useful for
creating patches to the software.
-h, --help Show this message.
Error: invalid option: --with-passenger
This is supposed to work... so yeah.
A late answer. Obviously the documentation on the passenger site is outdated at time of this writing.
According to phusion's github site
https://github.com/phusion/passenger/issues/2187#issue-416881033
the config option --nginx-with-passenger is not valid anymore.
Instead do:
brew install nginx passenger
Addendum:
When using google search for results currently the old page comes up at the top of the list. Here's the currently maintained page with the accurate information:

I'm trying to set up a Ruby on Rails environment within OpenSuse, but I've encountered a problem. When running sudo zypper install rubygem-railties-3_2 all I get is File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/repositories/Banshee/12.1/'. So something seems to be wrong at their side.
Is there anyone who as a workaround for, or more info about, this problem?
When running the command $ sudo zypper up I was receiving a similar error:
File ... not found on medium http:// ...
Detailed error:
File './x86_64/libxkbcommon0-0.7.2-48.2.x86_64.rpm' not found on medium 'http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/'
The solution which worked for me was to run $ sudo zypper ref before running $ sudo zypper up
Obviously, you have setup an additional repository for Banshee for a very old opensuse version. Opensuse only keeps its repositories alive for the last two two releases to the current release. For this reason, you get this error. You can disable or remove the repositorium to resolve the error.
In order to install packages that are not part of the currently configured repositories, it is the easiest to use the one-click install available at https://software.opensuse.org/search .
I have a NodeJS/Express Dokku container. I'm trying to use a node module which just runs the wkhtmltopdf command from shell, but it can't find wkhtmltopdf.
Anyone have any experience with this?
You need to check how wkhtmltopdf was installed in that image.
As mentioned in node-wkhtmltopdf issues 32:
The wkhtmltopdf command is executed as a shell command on non-Windows systems.
Make sure the /usr/local/bin directory is in your $PATH variable. Do this by running:
$ sh
sh-3.2$ which wkhtmltopdf # Or try:
sh-3.2$ echo $PATH
sh-3.2$ exit
(In your case, you can do a sudo docker exec -it <containerIdOrName> sh)
The same issue adds:
What I ended up doing was downloading the dmg directly from wkhtmltopdf and that seemed to do the trick.
That means you might have to create a new image from the current one, installing wkhtmltopdf that way (with the dmg package)
jsonfry what installing wkhtmltopdf as a service container means: openlabs/docker-wkhtmltopdf-aas illustrates the installation process.
I got into the same issue as you did. I didn't want to run wkhtmltopdf in another container nor did I want to change the code to use remote calls. Since downloading wkhtmltopdf using apt-get plugin may result in a package that throws errors, I have created a new plugin that should set up wkhtmltopdf in the dokku container for you.
It is licensed using MIT license so feel free to do whatever you want. Hopefully it will help somebody.

I am attempting to follow instructions on this page:
http://www.agilereasoning.com/2011/05/25/ruby-on-rails-on-windows-7-using-cygwin/
I have been trying to install Rails with varying success first using the railsinstaller and I encounter difficulties like no vim and I couldn't copy and paste from the Windows command prompt so I install CYGWIN. It didn't download the files correctly so I downloaded them manually and some were hard to locate. I couldn't find the final package as a .tar file so I downloaded libxslt-devel-1.1.20-1.i386.rpm.
Right click the Cygwin shortcut and choose edit from the menu. Change the contents to >match:
1 #echo off
2 C:\cygwin\bin\rxvt -sr -sl 1500 -e C:\cygwin\bin\bash.exe --login -i
Do I have to put this as a command to run on the executable or inside the cygwin commmand prompt? When I try to do that I get this:
-bash: 'command': command not found
Lots of things wrong here.
You can copy/paste the command prompt with Edit->Mark or Edit->Paste
libxslt-devel-1.1.20-1.i386.rpm is a linux file.
C:\cygwin\bin\rxvt - why are you mesing around with rxvt?
I recommend you install the rubyinstaller + devkit and then do gem install rails. However don't expect to be happy with rails' performance on windows.
Ruby on Rails on Windows via CYGWINTry:
Install Vagrant
Virtual Box,
and Cygwin (or PuTTy, I am using Cygwin).
With this set, open Cygwin, go to your project folder, run vagrant init <box> (my box is hashicorp/precise64 - see others)
(you may also want to cfg your Vagrantfile?). All set, Run: vagrant up and vagrant ssh
Now you have a virtual machine (Ubuntu) running, and you can install rvm (recommended... so you can have different versions of Ruby), or go directly with ruby, rails, etc.. (sudo apt-get ruby -v x.x.x,etc)
- Vagrant "creates and configures lightweight, reproducible, and portable development environments".
- Cygwin helps with ssh issues, etc...
- Virtual Box manages the machine (Ubuntu, or other OS)
With this set, I have no problem at all running Ruby (on Rails) with Windows.
