Spyder fails to launch

[GoogleCodeExporter]

If relevant, please answer to the following questions:
1. What version of Python(x,y) have you installed?
2.7.3.1

2. Which components have you installed (Python(x,y) installer:
    All the defaults, plus I added vpython, scipy.

3. Have you selected the option "Customize installation directories"?
    No

5. Where did you install Python(x,y) itself?
    default path

6. Have you installed Python(x,y):
 For "All users"

7. What is your operating system?
Windows 7

8. Is the operating system 64 bit?
 No

9. When you installed Python(x,y), were you logged in as :
 a regular user

10. If you are using Windows Vista/7, have you installed Python(x,y):
 simply by double-clicking on the installer

11. Regarding installed software on your machine, how did you clean your
machine before installing Python(x,y)  (multiple answers are possible):
 uninstalled any previous Python distribution 

What steps will reproduce the problem?
1. Reinstalling Python(x,y)
2. Opening Home screen
3. Clicking Spyder shortcut icon 

What is the expected output? What do you see instead?
I expect Spyder interface to open, but it just 'thinks' for a moment then does 
nothing. (In '--debug' mode a terminal window appears for a second then 
vanishes, but Spyder still does not open.)

Note: it was working fine the first time I downloaded Python(x,y) (same 
version), but today I clicked on it and it didn't run all of a sudden. I 
restarted my computer, uninstalled/re-installed the whole program, but no luck. 
I also found a previous thread the problem was someone's security scanner, so I 
added an exception for C:\Python27\Scripts\spyder, to no avail.

1. check your path setting - PyQt should be listed first
2. Run "Reset Spyder" from the start menu 
start->Programs->Python(x,y)->spyder->Reset Spyder

Thanks - The path does list PyQt4 first, and I ran Reset Spyder, but it still 
does not open. (Note: it will not open directly from the start menu either.)
Do you have another suggestion?

Thank you for your response. I did try 2.7.5.0, with the same result.

The output is as follows:

backup C:\Users\asalmoir\.spyder2\.spyder.ini and delete it.

Try again.

Exactly the same problem for me. I Can't launch spyder. (windows XP)

I've tried "python c:\Python27\Scripts\spyder". There is an output, but it 
immediately disappears (window closed)

Do you have an idea ?

Please try this from the command line.

I deleted the spider.ini.bak file and tried again.
The file was re-created and the output was exactly the same.

Delete C:\Users\asalmoir\.spyder2\.spyder.ini - not the backup.

Sorry, to clarify, there was no file named \.spyder2\.spyder.ini so I assumed 
you meant the other one. There is one called \.spyder2\.spyder - type is a 
configuration file. Is that it?

Yes.

OK it seems to be working now. 
I deleted that file, and also had just reinstalled Python(x,y) again and 
restarted my computer.
Thanks for the help!

I am facing the above issue with python(x,y). Version: 2.7.5.0. OS: Windows XP, 
service pack 3. 

I tried removing the .spyder.ini file, reinstalled the software and rebooted 
the machine, nothing seems to work.

Following is the output of "python c:\Python27\Scripts\spyder"

I have the same issue -- one once Windows 7 computer it stops launching 
sometimes.

My solution, working for me, is to reinstall Spyder, but uninstall does not 
completely remove all hidden file. Do the following:
* Uninstall spyder
* make sure folder settings show hidden files (Tools>Folder Option>ViewTab -- 
click "show hidden files"
* Go to C:\Users\yourusername -- delete the whole ".spyder2" directory
* Reinstall spyder -- works again at least with my PC

I tried a direct and brute force version without uninstalling: deleting 
.spyder2 directory. Run spyder again and it worked for me.

Newer Python(x, y) no longer supports Windows XP. As MS will stop all support 
as of April 2014 (2 months from now).

Please use an older version.

I had the same problem. Then I also run "python c:\Python27\Scipts\spyder". 
then it shows some error. Then go to .spyder2 folder, and delete the file 
.spyder.ini, run the spyder again. It works. Thanks.

I had the same problem with Spyder (Windows8 64 bits) but i didn't found the 
file in .spyder folder : spyder.ini so i deleted .spyder (a configuration file) 
and now it works.Thanks

I had exactly the same problem (spyeder does not launch from python(x,y) tool), 
but you can fix it by going to the
C:\Users\Name\.spyder2

directory and remove the complete directory called spyder.lock

Now the launcher did work. I think the last time I did not close spider 
properly and therefore the lock file was still left. No need to reinstall 
everything anyway

I changed C:\Python27\Scripts\spyder-script.py to:

#!python.exe
from spyderlib import start_app
start_app.main()

and worked fine

I just removed directory called .spyder2 and it works ;) !

Deleting C:\Users\<user>\.spyder2\spyder.ini and then starting Spyder worked 
for me.

I had the same problem. I just deleted the directory .spyder2 and it worked for

I accidentally saved something in the spyder.lock file and that started 
creating a bunch of other files in the same directory. make sure there is only 
one original spyder.lock file and delete any files in those files.
