I am attempting to use Pipenv with Pydev and I am encountering a problem. If you use Pipenv standalone, you can use the environment variable WORKON_HOME to specify where the virtual environment should be created. It does not appear possible to do this in a Pydev environment and I am at a loss to know how to proceed. I am running Eclipse and Pydev under Windows 10

I have a new computer (Windows 10, 64bit) and I can't install Eclipse.
I downloaded a file called "eclipse-inst-win64.exe" and a file called "jdk-12.0.1_windows-x64_bin". When I try to open or run as and administrator the Eclipse, I recieve the following message:
"A Java Runtime Enviorment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse Installer. No Java virtual machine was found after searching the following locations:
C:\Users\USER\Downloads\eclipse-inst-win64\jre\bin\javaw.exe
javaw.exe in your current PATH".
What did I do wrong? What should I do? Thanks.
Of course, you have to install jdk FIRST. Make sure to set your JAVA_HOME system environment variable to the folder where you installt jdk-12.0.1 and add the bin folder of the jdk to the PATH environment variable. You can test your installation: open a PowerShell and execute java -version. It should display your installed version. If not, the variables are not set correct.
i need to execute a ant script inside eclipse luna using java 7.
The problem is that if i try to change the path with jenv or try to set JAVA_HOME inside eclipse the ant script inside eclipse is always executed with java 6.
The OS is macOS Sierra.
I have to use eclipse.ini ?
Thanks
Assuming you are running the Ant script the normal way you can configure this in the configuration for the script.
Open the External Tools Configuration dialog using 'Run > External Tools > External Tools Configuration...'.
Find your script in the 'Ant Build' section and then look at the 'JRE' tab where you can set the JRE/JDK to anything you have told Eclipse about.
I have been using Spring STS 3.7.2 for a few months on my Mac laptop (Mac OS X Yosemite 10.10.5). But suddenly the STS IDE is not starting up. I suspect that one of the automatic OS update may have changed something, since I noticed that I don't see java any more on my path setting.
I manually added the following entries to my .bash_profile and updated using source command:
export PATH=$PATH:/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/jre/bin
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home
But STS stubbornly not working. It keeps giving me the error message in a dialog box:
A java runtime environment (JRE) or Java development kit (JDK) must
be available in order to run STS. No Java virtual machine was found
after searching ....
I am confused. I am able to invoke java from any terminal window, as well as JAVA_HOME environment variable is set.
Any ideas what may be going on?
After quite a bit of searching online, I figured out the problem, and resolved it for myself. It basically boils down to JDK upgrade to versions beyond 1.6.
The following link provided a solution:
https://apple.stackexchange.com/questions/178647/jdk-platform-not-recognized-running-eclipse-or-mvn
Here are the steps:
Revert back to JDK 1.6: Download and install JDK 1.6 from this Apple site: https://support.apple.com/kb/DL1572?locale=en_US
Change the PATH variable to point to the 'bin' directory of where JDK is installed. On my Mac, it was installed at: /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin
Go to the STS application installed directory and run the command "open -a STS.app". This will open the STS IDE successfully.
Exit STS.
Now, if you want to use Java 8, then change the PATH variable to the Java 8 directory. On my Mac, it was at: /Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/bin
Launch the STS app again, and voila!, the problem solved.
Eclipse gave me an error specifying that no JRE is installed while I was trying to configure Erlide in eclipse.
I added path to erlang directory in 'System Variables'. Then I installed erlang plugin for eclipse, added erlang installation directory path in Eclipse preferences and restarted Eclipse.
After restarting eclipse started giving me error about JRE.
Below steps might help you to solve your problem.
Install JDK and JRE - Here are step by step Instructions OR ANOTHER
Verify you setup JAVA_HOME and JRE_HOME and PATH into environment variable.
You can also investigate your Java version via Command Prompt:
Open a Command Prompt (Navigate to “Start” => “Run” and type “cmd”)
Then enter the following command:
java –version
If you don't see your java version you have to follow step 1 carefully again
Installed eclipse/ if already installed open the same. Here are step by step Instructions
NOTE: Make sure that you have same bits for both JDK and EClipse (32 or 64). One way is to verify in your ini file.
To develop a Java program, you need a JDK not only a JRE.
Do you have a JDK installed? Have you tried to run jar, $ set | grep "JAVA_HOME" (Linux) or C:\> set | find "JAVA_HOME" (Windows) in your command prompt to see if you have Java configured in your machine?
Once you install your JDK you need to set this environment variable.
Maybe Earlide is not compatible with your JDK 1.8, can you try with jdk 1.6
I am trying to run Eclipse Galileo, but having following error message on screen:
I have installed jdk-6u21-windows-x64 and also added the environment variables in the PATH. I am running Windows 7 64-bit.
If you're going to use a 64-bit JDK, you should probably get the 64-bit Eclipse instead. They really should match.
