I'm trying to install some development platform on Ubuntu 20.04. Here is what was said on the install-manual:
check the screenshot here :D
I'm not sure what to do now. It seems that I should modify the $CMAKE_PREFIX_PATH by creating a "nrp_variable" in the .bashrc file. But I don't know the syntax, which could achieve it correctly.
CMAKE_PREFIX_PATH is environment variable and you can just run printenv CMAKE_PREFIX_PATH to see content.
Also to solve issue try running command in green box.

I am trying to get mujoco_py running. When I do
import mujoco_py
I get this error:
Exception:
Missing path to your environment variable.
Current values LD_LIBRARY_PATH=
Please add following line to .bashrc:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/jonah/.mujoco/mjpro150/bin
I have added the above line to both /etc/skel/.bashrc and ~/.bashrc. If I run
echo $LD_LIBRARY_PATH
I get
/home/jonah/.mujoco/mjpro150/bin/
My .mujoco folder includes mjkey.txt and the mjpro150 folder. I can run ./simulate successfully, so I have a feeling that this is some kind of mujoco_py specific bug.
Which program do you use to import mujoco?
I had a similar issue using mujoco_py with PyCharm Community 2018.1. A workaround was to launch PyCharm from the terminal instead of using the launcher icon. Maybe it could help with your issue too.
Otherwise you could try adding the LD_LIBRARY_PATH to ~/.profile instead of ~/.bashrc, as proposed in this answer here: https://askubuntu.com/questions/1022836/python-not-recognizing-ld-library-path/1022913#1022913
You can try to reinstall Pycharm for the newest version.
After you save the .bashrc file your want execute this code.
source ~/.bashrc
Now link is updated.
Please check the user which you run the code with. The mismatch user will cause this problem. There is the checklist may help you:
Don’t use ‘sudo’ to run the code;
Don’t use ‘sudo’ or virtual environment (e.g., anaconda) to run Pycharm (If you run the code in Pycharm).
I Installed Ubuntu 14-04 LTS. I tried to install software's using Terminal.Each time Software Installation successful but after installation it always diSlays one command which is '-System-Product-Name:~$ '.I applied many this like my computer name etc.But not yet success.
I am new in Linux platform.Anyone aware solution for the same please help me.Thanks In advance
Add the following line to .bashrc file in your /home/your-username folder
export PS1="\[\e[0;32m\]\u#\h:\e[m\] \[\e[1;34m\]\w$\e[0m "
execute the command
source .bashrc
Then read

System-Product-Name is the default hostname.
To change it, you can run sudo nano /etc/hostname, modify it with something like yourname-desktop
I would like to customize the $PATH variables included in the Cygwin environment, how can I do this? One solution I know of is to add the following line to the end of the Cygwin.bat file:
PATH="/usr/local/bin:/usr/bin:/bin"
By default the shortcut starts bin/mintty.exe, how can I change that default behavior?
All Windows environment variables are included in your Cygwin environment automatically on startup. If you'd like to customize what they are, you can overwrite the whole $PATH variable using a line similar to what you already mentioned in your Cygwin.bat file:
PATH="colon:separated:list:of:all:paths"
Also if you'd like to change which terminal is used by Cygwin, one alternative is rxvt.
Another popular solution seems to be using PuttyCyg to putty directly into your Cygwin installation to get the benefits of the Putty terminal. See the effective-cygwin
GitHub page for setup instructions and more.
See this stackoverflow post for a full list of suggested alternatives to the default Cygwin terminal.
Background: I am trying to run a windows-installed version of python from within cygwin, rather than the cygwin version (some packages I am using prefer the non-cygwin version). The following post got me up and running: Using Windows Python from Cygwin. However, I am now having an issue.
Problem: The PYTHONPATH variable does not seem to be working for me. I try "import module1" when I am using python in an arbitrary directory. module1 is located here: c:\cygwin\home\mcsefl\testFolder\module1.py. And my PYTHONPATH variable is set in my .bashrc file in the following way: "export PYTHONPATH=$PYTHONPATH:/home/mcsefl/testFolder". However I still get a "No module named..." error.
Alternate tries: Since I am running the Windows Python, I thought perhaps python did not care about the cygwin environment variables (not sure if this is true..?) So, I also tried to set the windows PYTHONPATH env variable in the control panel of windows with no luck as well.
Thanks in advance
I deleted the line in my .bashrc file that tried to set the PYTHONPATH variable and just let it be set by Windows. This corrects the problem.
Side note: The title for this Question is a misnomer now that I re-read it. My issue was resolved without addressing that overall question
I'm using Netbeans on Linux (Ubuntu 9.04) to build a C project.
How do I pass in an environment variable so that's it's visible to the Makefile?
If I do a normal export MYVAR="xyz" and then run make from the command line this works fine of course.
But Netbeans doesn't seems to use the .bashrc environment, so if I click "build" in Netbeans, the make fails.
Interestingly, the problem doesn't seem to occur on MacOSX - I've added the variable to ~/.MacOSX/environment.plist, and that value is visible to Netbeans.
I found this post which suggested modifying ~/netbeans-6.8/etc/netbeans.conf. I've tried this, by adding -J-DMYVAR=xyz to the end of netbeans_default_options, ie:
netbeans_default_options="-J-client -J-Xverify:none -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true -J-DMYVAR=xyz"
But this didn't seem to work.
Edit:
This answer is possibly not valid for Unity-based flavours of Ubuntu.
The issue is actually nothing to do with NetBeans - it's related to the Ubuntu (ie Gnome) Launcher.
As this blog post explains, you need to add variables to the rather obscure ~/.gnomerc (No Mercy? :) file in order for them to be passed to applications started with Launcher!
So just edit ~/.gnomerc and add the variables as you would to ~/.bashrc, eg:
export MYVAR="xyz"
and logout/login.
