I am using chef resource package to install, it always get installed to the default location. Say for example, the code below will install in /etc/httpd
package "httpd" do
action :install
end
If I want to have it installed to a custom location, what is the way to achieve it?
Regards,
Pradip
There is an options property you can use to pass command line arguments to whatever the underlying package install command, but few OSes support relocation for distro packages so this is likely to go very poorly. Assuming you are using yum, it would be
package "httpd" do
options "--installroot=/path"
end

Hello guys. Can someone help me about this one? I cant install mongodb because of dependency problem. I already tried updating my linux mint terminal.
dpkg: dependency problems prevent configuration of mongodb-enterprise-server:
mongodb-enterprise-server depends on libcurl3 (>= 7.16.2); however:
Package libcurl3 is not installed.
mongodb-enterprise-server depends on snmp; however:
Package snmp is not installed.
Installing via dpkg -i mongodb.deb will not include additional package dependencies. You should be able to fix your installation by following up with sudo apt --fix-broken install.
Unless you have strong reasons to avoid the standard process I would recommend following the tutorial to Install MongoDB Enterprise by adding the appropriate repo definitions. Adding the normal package repo will also make it easier for you to update to newer minor releases of MongoDB 4.0.x.
I tried to import the biopython package in Spyder and got the error message:
ModuleNotFoundError: No module named 'biopython'
although biopython is installed.
I also checked the PYTHONPATH: there is a path set into the directory where the packages are stored.
Can somebody help? Did I miss something? Thanks for your help!
If you're using Anaconda, it's best to install all the packages you want from Anaconda if possible. You can check if a package is available with (e.g.):
conda search biopython
When I try that command it shows that biopython is available, so assuming you have access to the standard conda channels you should be able to get it this way.
Assuming you haven't already created a conda environment to work with, start by creating a new one with the packages you want to use:
conda create -n myenvname spyder biopython
where myenvname is the name you want to give the environment - call it whatever you like. If you want to use other packages as well, add their names to the end of this command. Then once the env is completed, activate it:
activate myenvname
or if this doesn't work, on Mac or Linux:
source activate myenvname
and start Spyder in this environment:
spyder
Each time you want to use this environment in future you will need to activate it first. You may also be able to do some of these tasks through the Anaconda Navigator or via Start menu shortcuts but the command line version will always work.
If there's a package you want that isn't available from conda but is available via pip, just use the pip command after creating and activating the environment.
If you are using Anaconda, a solution could be
conda install -c main biopython
following https://anaconda.org/main/biopython.
The official repository page helped me when I got your error message because numpy was not in place.
I can install a Racket package with:
raco pkg install <pkg-name>
If the package is not installed, it installs it. If the package is already installed however, it will complain that the package is already installed. While this is fine, is there a better way to check if a package is installed, and only try to install it if its not already installed?
For context, I want this because I have a (non-package) Racket project that relies on certain packages being installed. I could put them in an info.rkt file, but as far as I can tell, these won't get installed unless I try to install the project as a package, which doesn't make sense for this domain.
So, is there anyway to determine if a Racket package is installed? Additionally, can I use this information to only install a package if its not already installed?
Yes, in fact you can. If you are using a shell program or makefile (basically, using the raco pkg tool from the command line), you can pass it the --skip-installed parameter. This will only try to install the package if its not already installed. So you could do something like this in a mace file:
all: # Replace spaces here with tabs, because make...
raco pkg install --skip-installed <important-pkg>
<rest-of-makefile>
Alternatively, if you are looking for an 'in Racket' solution, you can use the installed-pkg-table function to get a hash table containing all of the installed packages. From there, its easy enough to do a hash-has-key? to see if the package is in the table. From there, you can use pkg-install-command to install the package. Your total code will look something like this:
(unless (hash-has-key? (installed-pkg-table) "<important-pkg>")
(pkg-install-command #:deps 'search-auto i))
I should note that there is a slight chance that the package database will change between searching for the key and installing the package. If that is important to you, check out with-pkg-lock
I have created a .deb package using equivs-build command and providing necessary control, preinst, postinst, etc. I noticed that version can also be mentioned in control file. Now I want to create a .deb package with updated source code and I want to enable user to upgrade the package if it is already installed (and is of previous version, of course), as I won't be changing conf related files, etc. One way I can think of is to write a shell-script which will first check for installed version, and will take actions accordingly (i.e. if installed, just update the source-code, database-migrations, etc. and if not, install the package using dpkg -i <package-name>). I was wondering if there was a way to achieve using dpkg only (something like dpkg upgrade <package-name>) which will handle installation or up-gradation as required.
That's already how it works.
dpkg -i package_0.123.deb will upgrade if the version of package is less than 0.123, removing the previous version if necessary (there's an option to force a downgrade, too). apt-get install package will install the newest version of package, removing the old one and upgrading to a new one if necessary. apt-get upgrade will upgrade all packages to the newest version.
Basically, just take care to monotonically upgrade the version number each time you publish a new build.
If you didn't specify a version previously, the default will be something simple like 1.0. Just make it bigger than that.
I have a Solaris package with depend file. When I install the package, it ignores the dependencies.
My depend file looks like this:
P SUNWcsu Core Solaris, (Usr)
P XXCore My core package
I am able to install the package even if XXCore is not installed.
My Prototype looks like this:
i pkginfo
i depend
i request
Thanks in advance.
BTW, other install files (request, checkinstall, etc) are handled correctly.
UPDATE:
I have made some changes to the depend file so it looks like one that works fine. I only changed Tab to white space. Now it behaves differently - I get the following:
Verifying package dependencies.
WARNING:
The XXCore package "My core package" is a
prerequisite package and should be installed.
Do you want to continue with the installation?
It is better, but I want the installation to stop, without the option to continue
Should you want to enforce a prerequisite, you can prevent the package installation by using a checkinstall or preinstall script that check for required the package presence and exit in error if not.
