Unable to gather python interpreter info for pydev - eclipse

Question

OS: Windows 7 x64
Python: 2.7.3
Pydev: 2.7.1.2012100913
Eclipse: Version: Juno Service Release 1 Build id: 20121004-1855
I am unable to configure a python interpreter in Pydev. If I try using the auto-configuration or the manual configuration I get the same type of error output:
Unable to gather the needed info from the system.
This usually means that your interpreter is not in the system PATH. No
output was in the standard output when trying to create the
interpreter info. The error output contains:>><<
or
See error log for details. No output was in the standard output when
trying to create the interpreter info. The error output contains:>><<
Python is in my PATH. Here is the output of interpreterInfo.py (stdout and stderr):

Any help would be great, thanks!

Answer 1

I did not expect such a problem: (PyDev worked on 27 64-bit PCs under Indigo; I tested The Same PyDev plus Python under Juno on a 32-bit Pc with success; Then by the first attempt on a 64-bit PC came the error ...
I have not used "autoconfig" at all. I was going the line
"File>New>PyDevProject> ...PrjectName... click_here_to_configure_an_interpreter_not_listed" when it happened."
After short googleing the luck came:-)
http://pydev.org/manual_101_interpreter.html
helped me to solve the problem ,
using just an alternative path to the same thing.
{1. Go to: window > preferences > PyDev > Interpreter - (Python/Jython/IronPython). ...}

Answer 2

I had a similar issue. I could not manually or automatically configure. I worked around the problem by re-installing python 2.7. After re-install auto-configuration worked.

Answer 3

I am running Python 3, so I had to make these
changes to get python.exe as my interpreter.
File:
C:\EasyEclipse-for-LAMP-1.2.2.2\extensions
\pydev-1.3.3\eclipse\plugins \org.python.pydev_1.3.3\PySrc
\interpreterInfo.py
Edit all occurrences of “print …” to “
print(…)
” (the … is whatever is being printed), so wrap it in quotes.
Comment out line 16, since True and False are
considered keywords in Python 3.
Save, and you should be able to successfully
set C:\Python32\python.exe as the interpreter.
I kept the default folders checked.

Answer 4

I encountered this problem on Windows after directly copying my python 2.7 (64bits) directory to a new computer. Neither automatic not manual configuration would work, and I had the same errors as you did.
I came back to the original installation, went to C:\Windows\System32 (you might also check SysWOW64, but I'm not sure Python even uses it) and fetched :
python27.dll
pythoncom27.dll
pythoncomloader27.dll
pywintypes27.dll
I copied them into the new computer's System32 and pydev's autoconfig was able to find my python interpreter from the environment variables.

Answer 5

Please Make sure you have installed proper version [32 or 64 bit] of python corresponding to your system OS version

Answer 6

I have a similar issue. Try to run "python --version" to see that python executes in your system

Answer 7

Install OS compatible python executable in your machine.
During installation remember to check "Add Python 3.8 to PATH. (as shown in this image)
Once Python installed successfully in your machine In Eclipse open in the Window -> Preference -> Pydev -> Interpreter -> Python Interpreters menu. (Assuming you already installed PyDev plugin in Eclipse).
Next select Config first in PATH option. (as shown in this image)
You can now see the Python interpreter info in eclipse. (as shown in this image)
