I'm getting error when sending notification using rpush gem after deploying on linux server while all notification data is saved into table.
On my local i was pushing notification by rpush push command but on linux this command is not found so please help me to sort out this problem.
rpush is not being found in your path (an environment variable which contains the file paths for all executable files). You can confirm this with the which command.
which rpush
The fact it returns nothing tells you it is not in your path. If it was in your path it will return the file path of the executable file that runs when you enter the command into the terminal.
Prior to adding it to your path, just check it is actually installed.
You can add it to the path by opening ~/.profile or ~/.bash_profile or ~/.bashrc (where the squiggle ~ is your home directory) and entering:
export PATH=$PATH:/path/to/rpush/executable
Then reload your terminal or type source ~/.profile for example.
For some documentation on paths there is the Linux Info site, and for Bash profiles you can check out this page.

I am trying to use Python to call a Google Cloud AI platform training API. The path to my service account key JSON file is "/Users/my_mac_username/service_account_key.json", and I added the export statement in the bash_profile file so that it looks like:
# Setting PATH for Python 3.8
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
export PATH
export GOOGLE_APPLICATION_CREDENTIALS="/Users/my_mac_username/service_account_key.json"
However, I still got the error:
google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials.
Besides, I have google-cloud-sdk folder installed. I would like to know in which file I should set the environment variable. Thanks for your help!
Assuming your terminal shell is bash, you have your environment variable setup correctly. The new variable will not be available until you reopen the terminal or run source ~/.bash_profile in the current terminal.
If you are running zsh, add the export in your ~/.zshrc file.
To determine which shell you're currently running, use: echo $SHELL from the command line
I typed command
source $HOME/$USER/.rvm/scripts/rvm
And there was no such file actually.
Now whenever I open command prompt I get that message
/home/cse/.rvm/scripts/rvm: No such file or directory
How to get rid of this?
Have you already added the file at .bash_profile or .bashrc ? If yes and the file does not exist then this is why you see this message. You must remove it from these files then you will not see this message.
I'm trying to write a shell script that automatically runs my rails app in a virtual machine.
My script code is this:
#!/bin/sh
PATH='/usr/local/rvm/gems/ruby-2.0.0-p481/bin'
cd /home/lgdelacruz/SampleApp
rails server
But for some reason it doesn't see all the dependencies. this gives me the error
/usr/bin/env: ruby: No such file or directory
I'm positive ruby is installed in the virtual machine. I can run rails server by manually going inside my virtual machine going to my SampleApp folder and running rails server there and everything works fine. But for some reason when I put all that in a shell script. it doesn't work.
You've probably got to initialize RVM in your script first. Try putting this line in:
source "$HOME/.rvm/scripts/rvm"
You might also need to specify a gemset, if you're using something other than the default:
rvm use #mygemset
See the RVM scripting docs for details.
In your shell script, you've reset your path to only include /usr/local/rvm/gems/ruby-2.0.0-p481/bin. ruby is usually installed somewhere like /usr/local/bin
instead you could concatenate that directory onto the end of your existing path.
something like:
export PATH=$PATH:/usr/local/rvm/gems/ruby-2.0.0.p482/bin
I am developing web applications using Ruby on Rails and Sublime Text 3 on OS X 10.8.4. I recently installed the package RubyTest. The tests only work when Sublime is launched using the command
subl
in terminal. Otherwise I get the error message:
/bin/sh: rspec: command not found
I think that's meant to be the case; that's implied in RubyTest's readme file on github.
However I'd like to retain the ability to launch from the dock. Is there a way I can do this?
Unfortunately, OSX applications do not pick up on your $PATH variable set in Terminal. To change the internal PATH settings in Mountain Lion (this method hasn't been tested with previous versions, although it should work), you'll need to edit /etc/launchd.conf:
Make sure you have admin privileges.
Open Terminal or your favorite substitute and see if there's anything in the file /etc/launchd.conf:
cat /etc/launchd.conf
If you get an error like
cat: /etc/launchd.con: No such file or directory
then continue with the next step. If the cat command does display some content, copy it to the clipboard.
Create a new text file with the following content, modified to fit your needs:
setenv PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/Users/YourUserName/bin:/path/to/gems/bin
If the cat command displayed some content in the previous step, paste it into the new file before the setenv PATH command. If it already contains a setenv PATH command, just modify it to add the directories you need, such as /path/to/gems/bin
Save the new file in your home directory (/Users/YourUserName) as launchd.conf.
Go back to Terminal and enter:
sudo mv ~/launchd.conf /etc
to use admin power to move the new file to /etc, replacing anything that was there before. Depending on your previous usage of the sudo command, you may get a short "be careful doing what you're doing" message, but either way you'll need to enter your password. /etc is not directly accessible through the Save dialog unless you're a real power user and know how to get around OSX's file system restrictions.
Reboot your computer
And you should be all set. If you're interested, launchd and launchctl use the csh/tcsh syntax, so you can't use the bash/zsh export PATH=/usr/local/bin:... format.

Command 'exiftool' not found (MiniExiftool::Error)
When I login with ssh and I type exiftool in any directory the command works properly.
I have the follwing line in both .bash_profile and .bashrc
export PATH=$PATH:$HOME/bin
Is it possible that Rails (MiniExiftool plugin) does not recognize that bash command? How can I fix this behaviour?
The PATH for the user your server runs as does not include the directory that exiftool is in. You can either add it to that user's path, or you can refer to exiftool using its full path. I'd recommend this second approach for reasons of security. There are a number of attacks that involve putting trojan horses in a user's path ahead of the directories where the real binaries live.
