|What version of scipy and matplotlib should I install on Mac Mountain Lion?|
It's hard to be 100% sure without a little more information, but I'm 99%
Your problem is that you're installing all this stuff for the MacPorts
Python, but then trying to run Apple's Python, which doesn't have any of it
installed. (Part of the reason I suspect this is that Apple's Python is
version 2.7.2, while MacPorts has been on 2.7.5 for a long time now. The
other part of the reason is that this is exactly the same kind of problem
people have when they install two different Python X.Y versions without
realizing that's what they're doing.)
If you want to use the MacPorts Python, run /opt/local/bin/python instead
of just python.
If you know what you're doing, you can change your PATH, or create a
symlink, etc., but I suspect you will just confuse yourself further.

|When creating a NuGet PowerShell script, how can you tell the difference between a new install and upgrade?|
I don't think it's possible to know if the current operation is install or

|How to Install Matplotlib Basemap Module on Windows 7 with WinPython (or any Python stack install)?|
I use windows. And my installation failed with official guidance, too.
Finally I installed Basemap using the following method. Although I am not
sure if it will go right for you, I just offer mine.
First of all, you must have pip in your computer. (It is much easier
to install, compared with Basemap and other things. And it can be
used to install many useful packages.)

|Error "invalid switch in RUBYOPT: -F (RuntimeError)" is shown while install gems by gem install mechanize|
I found the reason. Just because there is a space in the installation path

Re-install the Ruby to the path which doesn't contain space, this error
will be fixed.
And, of course, AutoRun should be removed from HKCUSoftwareMicrosoftCommand

There is most likely a problem with the certificate. Try making a new
certificate, keystore, and alias, then generate the .apk again. Make sure
that no previous instance of the app is on the phone when you try to
install this new version or the mismatch of signatures will cause the
installation to fail.
Also, was there a previous version of the app installed on their phones
already? The signature mismatch may occur due to the use of both signed and
unsigned(in reality the .apk is singed, but it is done automatically by the
|Why "bundle install" try to install outdated version of gems?|
bundle install or in short bundle does not install the latest gem unless
you have left out the version in your Gemfile. e.g.
But usually this is not the case, we specify versions to prevent
application from "crashing" when some gems are updated and we unknowingly
run bundle update, or for that matter move application to say test or
production servers. Usually when adding a gem to Gemfile, we do:
gem 'rails', '~> 3.2.7'
Note the leading ~> in the version number. This says: use rails gem
between versions 3.2.7 and less than 3.3.0.
In order for your bundle command to grab rails 4.0, you need to change that
line to read either one of the following:
gem 'rails', '>= 3.2.7'
gem 'rails', '4.0.0'
If you use gem 'rails', '>= 3.2.7' then your rails appl
If you are deploying a Node app, declare it in your package.json,
otherwise, specific it in your gemfile.
|Bundle install gets permission issues with global RVM install|
This error doesn't necessarily need to be solved.
Your bundle is installing properly, but it's not able to remove cached
gems. It's a pretty harmless error unless you're running way short on hard
I actually get this same error too. The problem is that my home directory
is remotely mounted, so local root doesn't have permission to modify items
there. Local root only has global write permissions on local directories. I
imagine, based on what you describe, that you have the same issue. You
could remove the files manually, or you could instruct rvm to install gems
in a directory on the local machine.
|Install multiple packages on linux (like pip install -r requirements.txt)|
Put the list of packages in a text file(say test.txt) with package names
separated by spaces, like this -
python ruby foo bar
then you can just install with apt-get like this -
sudo apt-get install $(cat test.txt)
|Rails : gem install vs. gemfile&bnudle install|
RubyGems is akin to a package manager for Ruby. It's a means by which you
can install self-contained libraries to use in your applications. When you
use gem install gemname you're installing that gem to the current machine
that you're developing on.
Bundler is a tool for managing the gems that your application depends on.
When you create a Gemfile, you list the various gems and their versions
that your application requires. This allows you to easily ensure that your
application has the gems it needs when you deploy it to a new location -
for example, when you push to Heroku, your Gemfile is used to determine all
the dependencies of your application.
Running bundle install will take the list of required gems in your gemfile
and install them if they aren't installed already, just like

|What's the pros and cons to install HBase + Hadoop together vs. install HBase and Hadoop seperately?|
Option 1: An integrated cluster.
Pros: MapReduce which reads or writes HBase will more efficient as the data
Cons: The HBase region server will reduce the performance of the machine
(Datanode and TaskTracker) as it need to hold some CPU and memory. The
HBase latency may be seconds if there are many MapReduce jobs. So if you
want to make HBase response in time, you need more work (For example, using
memcache to improve the read performance).
Option 2: 2 clusters.
Prons: The HBase region server will not impact the performance of the HDFS
Datenode and the TaskTracker.
Cons: MapReduce needs to read and write the data remotely if it wants to
access HBase. The option also needs more machines.

|Why is "install" run twice?|
$ bundle install --without production prevents bundler from installing any
of the production gems. It also gets saved in your local repository and
you don't have to run it more than once. Any subsequent run of bundle
install will include --without production.
bundle install installs only the missing gems from your Gemfile, while
bundle update updates/installs every single gem to the latest version as
specified in the GemFile..
