Pydev Perspective Not Showing After Install For Eclipse

I had the same problem; it seems I was using Eclipse with Java 1.6 instead of with Java 1.7 as required by PyDev.

The fix, for PyDev 3.1.0 on Linux at least, is to start Eclipse with the Java 1.7 binary. Two ways to do this: updating the default Java installation for the system to 1.7 or edit the eclipse.ini to point to a Java 1.7 java binary.

1. Update your Java to the latest SDK.
2. Restart Eclipse.

PyDev will be shown in Eclipse>>Preferences

For Ubuntu users:

Check for Java version ($ java -version). If it is 1.6.0, please upgrade it to 1.7.0 ($ sudo apt-get install openjdk-7-jdk)

Also, run the command $ sudo update-alternatives --config java

Restart Eclipse and Pydev will show up in the preferences.

The PyDev installation guide addresses this issue. The solution is to update to Java 7 or later.

Edit: As @aaron-hall suggested, I’ll give a more detailed explanation:

The nice folks that develop PyDev have decided to upgrade the Java version they are using (wise decision, but breaks compatibility backwards). If you have Java 6, then you need to upgrade at least to 7 (you can find numerous sites explaining how to do it in case you don’t know). After you have installed the new version of Java, inside Eclipse go to Preferences/Java/Installed JREs and add your recently installed JRE. After that, restart Eclipse and install PyDev as you normally would. Everything should work fine now.

If for some reason you can’t or won’t install Java 7 or 8, then you must stick to PyDev 2.8.x.

My solution was to run eclipse from the command line with the -clean flag:

eclipse -clean

This has to be done once in a while around package upgrades.

in my case, you need to use jdk 1.8, if the pydev is 5.0.0.

As per PyDev documentation states, the latest 5.x version now requires Java8 and Eclipse 4.5 onwards (http://www.pydev.org/)

You can use a 4.x PyDev version, which requires Java7, using the alternative update sites (http://www.pydev.org/update_sites/index.html)

I went through all the above steps, but it didn’t work. At last, I saw that my launcher pointed to a wrong Java installation. It was:

   eclipse -vm /usr/local/java/jre1.7.0_67/bin/java

then I corrected to the java installation appropriate for my case, as stated in the previous answers, and it works:

   eclipse -vm /usr/lib/jvm/java-8-openjdk-i386/bin/java

Of course these are my installation dependent paths. You should check your owns.

There are a few things that has to be checked when installing pydev from install new software on eclipse.

1. Version of eclipse
2. Version of java

If you are using java 7 and still you cant find pydev under preferences(that happened to me), there is a good chance that you have installed a version of pydev which is above 4.5.5. PyDev 4.5.5 is the last release supporting Java 7 and Eclipse 3.8. For more details, go through this link http://www.pydev.org/ under release 5.2.0.
Like wise for java 6, an older version of pydev will help solve the issue, and there are a lot of sites which will find your right version of pydev according to your eclipse and java version

First things first, go to pydev offcial page, it stated:

See: the PyDev does not appear after install section on the download
page for help on using a Java 8 vm in Eclipse.

Visits this page, it shows:

Well, the main issue at this time is that PyDev requires Java 8 in
order to run. So, if you don’t want to support PyDev by going the
LiClipse route (which is mostly a PyDev standalone plus some goodies),
you may have to go through some loops to make sure that you’re
actually using Java 8 to run Eclipse/PyDev (as explained below).

Also, keep in mind that PyDev 5.x requires Eclipse 4.6 onwards (for
Eclipse 3.8 use PyDev 4.x).

In my system:

$ java -version
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-8u102-b14.1-2-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

According to this answer

Java 8 (a.k.a 1.8)

So my openJDK 1.8 is Java 8 already met the requirement stated from the pydev statement above. So it’s not Java problem in my case.

Recall the pydev last statement:

Also, keep in mind that PyDev 5.x requires Eclipse 4.6 onwards (for
Eclipse 3.8 use PyDev 4.x).

So I check my eclipse version, it’s merely old version 3.8.1:

But what I’ve downloaded is latest version pydev 5.3.0, which is wrong, so now what I have to do is follow this instruction to uninstall pydev 5.3.0 first:

Use Shift key to highlight both and uninstall:

After uninstalled, visits this page to copy the old repo link:

Recall the pydev last statement again:

Also, keep in mind that PyDev 5.x requires Eclipse 4.6 onwards (for
Eclipse 3.8 use PyDev 4.x).

My eclipse is 3.8.1, so I just have to choose 4.x. The highest version of 4.x listed above is 4.5.5.

I copy the link http://www.pydev.org/update_sites/4.5.5 and paste into eclipse’s Install New Software page to install:

After all, Windows -> Preferences, pydev is showing up now:

Solved with updating vm args. Just pointed to java8.

-vm E:/sw/java/jdk1.8.0_91/bin/javaw.exe

update Java version.
Install the new java.
Go to Eclipse-> Preference-> Java -> Intalled JRE -> Check latest java (1.8) -> Apply. Restart Eclipse

I faced this issue. My environment looked like this

• Windows 7 Enterprise (64 bit)
• Eclipse SDK 4.2
• Python 3.6.1
• Pydev 5.2
• JRE 1.8.0_111

In the above configuration the PyDev plugin didn’t show up.

I did the following:

• Installed the jdk 1.8 (64 bit)
• Installed Eclipse Neon
• Installed the Pydev plugin using the Plugin manager.

All works fine now !

It is clearly stated in the installation instructions that PyDev requires Java 8 and Eclipse 4.6 (Neon) in order to run and only supports Python 2.6 onwards.

In my case, while installing the plugin, I had forgotten to click on a checkbox to trust a certificate, then I installed it again, checked the checkbox and it worked.

If anybody has Eclipse Neon, this is how I fixed it:

1. From the Window menu > Perspective > Customize
2. Check Pydev Debug and the sub-items you’re interested in.

Now you can see the Pydev on the Menu bar.

I had the problem too, and I solved it just by waiting for eclipse to download all files, it takes some time.
When the downloads are completed eclipse will remind you to restart, if you see that remind you have succeeded.

I installed Eclipse IDE for Java Developers (setup by Oomph) into the folder ‘C:Program Files’ with administrator privileges on Windows. After manually renaming/moving the Eclipse installation folder and installing PyDev, it did not show up as Perspective.

A possible solution is to run Eclipse as administrator and to reinstall PyDev.

Note: When the initial installation directory of Eclipse is not changed, PyDev also works correctly.
