enter image description hereI am working object detection project. Firstly, i need to downloading “pip” and I did it. But i got an error(like in photo), and I haven’t any idea. How can i solve, do you have any idea?
You need to prefix your commands with sudo because they are meant to be run as root.
Example: sudo apt-get update.
Be careful when using sudo, you can really mess up a system as root.

I'm trying to build a script for linux to help me each time I install linux from scratch.
The Script have to 1.- Add repositories 2.- Install software from those repositories.
Adding repositories are not the problem, the problem is when i try to install software from this repo.
For the Repo:
sudo add-apt-repository -y ppa:webupd8team/java
After that, the script should make an update, so:
sudo apt-get update
It looks simple, but is not, because I receive an error:
The command Update could not be found.
And so on the rest of the softwares
apt-get -y install oracle-java8-installer
The package oracle-java8-installer couldn't be found..
I really don't know what should I do, nothing looks to work, I gave full rigths to the file and so on... always the same error.
But if I run the command apt-get install direct from the terminal, works without problem..
Any help?
actually I wrote a script in windows to use it in future Linux installations, for some reasons it doesn't work as I want it. Thinking it was a command or misspelled words, I search for a solution, wich didn't help anyways.
Debugging my script in a virtual Machine, I found that the script was giving some random errors like '/r' doesn't support and like that. Really weird because after searching in my script for that line code I didn't find it.
With that in mind, I search again for those errors, and found that for some reasons, if you write your code in a Windows maschine, it save it in a crlf type, wich in a Linux system is interpreted really wrong.
A solution of some users was converting the type from CRLF to LF, wich in linux is using the command dos2unix.
dos2unix filename.sh
After making that and runing my script again everything works perfectly.
I just installed Shopify's 'Slate' package using npm.
Terminal shows that the package was added to '/.npm-packages/lib'.
However, when I attempt to build a new shopify theme using the command 'slate theme newthemename', the command isn't found...
...even though slate clearly was installed.
Curious to figure out what I'm doing wrong, so any help/advice is much appreciated!
Please execute the below command from your terminal.
npm link #shopify/slate
Basically this command creates a symlink to your package folder, it will check for the global (npm) modules first, and will check for the local modules if there is no match.
Hope this helps!
Your installation of slate is successful. However, the slate program (slate/lib/index.js) is not added to environment variable PATH, that's why error command not found is reported.
To fix this issue, a simple method is add slate/lib/index.js to PATH manually. For example, create a symbolic link in /usr/local/bin/ and make it point to slate/lib/index.js:
sudo ln -s /<absolute_path>/#shopify/slate/lib/index.js /usr/local/bin/slate
Please note the first parameter of ln -s must be absolute path. If relative path is used, Mac OS X (I'm on 10.12.6) won't help to translate it.
I am working with this software (rtabmap in Ubuntu 14.04 with ROS Indigo) and I was having some trouble with the installation. So I decided to remove eveything and uninstall it:
apt-get remove rtabmap
apt-get remove ros-indigo-rtabmap
cd rtabmap/build
make uninstall
And late I have removed the whole rtabmap folder.
So now I just run in the console rtabmap and it initiates, it even shows me other options like rtabmap-camera.
My question is, how is this even possible? And how can I locate the damm package in order to remove it?
Note: dpkg does not find it in any way.
So actually I found the answer myself. It turned out that the binary files of rtabmap where written in /usr/local/bin and there were 2 versions of rtabmap. This way the make was taking the incorrect version and was giving me weird errors.
I just removed the binary files and reinstall over eveything again and now it works.
Cheers
Brace yourself, I'm a Windows admin messing with a CentOS 6 server.
Let's start by saying I know very little about Linux.
I'm trying to load an rmmagent, GFI/MaxFocus's agent. It's failing the dependency check on kernel-utils and unzip.
error: Failed dependencies:
kernel-utils is needed by rmmagent-1.0.2.centos6-1.2.x86_64
unzip is needed by rmmagent-1.0.2.centos6-1.2.x86_64
I Googled myself to death, but I think I just don't know enough about Linux to make this go.
Can someone educate me or point me to the right place to learn how to do this? Thanks!
-Jeff
PS: I got unzip installed without issue.
We had the same issue. We spoke to the LogicNow support and they give us this solution:
wget -c ftp://rpmfind.net/linux/Mandriva/official/9.1/i586/Mandrake/RPMS/ksymoops-2.4.8-1mdk.i586.rpm
yum install ksymoops-2.4.8-1mdk.i586.rpm
I'm using libspotify 12.1.103.gd51f6226 Release Linux-armv6-bcm2708hardfp on my Raspberry Pi and I think that everything worked out alright with the instruction in the readme.
I changed out appkey.c for my appkey as given by spotify but when I run the spshell example and try to login, I get an error
FATAL, TERMINATING: failed to log in to Spotify: Cannot connect to Spotify
Logged out
Exiting...
I'm sure that I'm using the correct username (I also tried email) and password (I also tried changing the password) and I've tried the jukebox example as well and get a similar error. I'm able to log into the website and the windows app just fine.
The one place that I think that I might have gone wrong is:
After this, ensure your PKG_CONFIG_PATH is set tocd
include the libspotify control file, and that the lib directory is
in the library search path.
I'm pretty sure that I did that okay and I don't get any errors during the build.
Any ideas?
I had the exact same problem, which you can see from my comments on this question. For me it turned out to be a problem with my username which contains a non-ascii letter ö. But since my plan all along was to use pyspotify I managed to log in using their jukebox example and hardcoding my username where appropriate and adding the nice little u infront of it, and now I can login to spotify, see line ~460 in the jukebox example:
session_m = Jukebox(options.username, options.password, True)
Which i changed to this:
session_m = Jukebox(u"username_with_ö", options.password, True)
Now my problem is another which is that I can't access /dev/dsp but that is an entirerly different problem. :)
EDIT
apt-get install alsa-oss solve the above mentioned problem, my raspberry is now playing music!
I can compile and login.
What I did was to simply extract the tar.gz to
And then..
sudo apt-get install libasound2-dev libreadline-dev
cd <libspotify folder>/share/doc/libspotify/examples
vim appkey.c
And then add the application key that you generate. But that seemed to work for you.
make LIBSPOTIFY_PATH=../../../..
spshell/spshell
Then I can login and do a lot of things, I haven't tried any audio yet since I don't have any speakers/headphones available.
If you install it instead using
cd <libspotify folder>
make install prefix=/usr/local
as described in the README also run
sudo ldconfig
to update the library cache, and then just do a normal compile.
cd <libspotify folder>/share/doc/libspotify/examples
make
If you suspect that you have compiled stuff the wrong way, do a "make clean" first.
Don't know if this is to any help but that is how far I have come.
