Recover default python path

[Andrey Mostovov]

Hi,

I unintentionally modified the default python path to a wrong one in the Preferences window of Spyder. After restarting it, the following error message showed up:

A Python or IPython Console failed to start!

and the python console was indeed disabled.

When trying to open the Preferences window in order to correct the python path, I get an error message in the Internal Console:

>>> Traceback (most recent call last):

I am not an advanced user so I do not see how to deal with this issue, I hope this is the right place to ask such questions.

Details: Mac OS 10.6.8, Spyder 2.2.5 (installed from dmg)

Thanks!

In your home directory find the .spyder2 directory. Look for the
spyder.ini field. In that file search for:

pythonstartup/default

It is probably set to False. Set to True:

pythonstartup/default = True


Restart Spyder

If that does not work then you have two options:

1) From the command line run spyder --defaults. This resets the
configuration settings to their defaults. This means any other
customizations you have done will also be lost.

2) Uninstall and then reinstall Spyder. Again you will be starting over.

Thanks! That worked!

I was looking everywhere for spyder initialization file. Unfortunately the folder you've mentioned is hidden in the standard configuration of Mac OS, so I probably wouldn't find the file without your help.

By the way, it would probably be useful to "secure" spyder from such situation, because if it has a wrong path to python interpreter it becomes totally disabled and you can not repair this without externally modifying ini file. Reinstallation didn't help by the way (the ini file remains the same after reinstallation)

Thanks!

In a terminal you can type

Be warned, however, that on Mac OS, this might give you the system default python rather than the setup which spyder uses (the latter command above should list all possibilities). Depending on how you installed python/spyder, it could be in a number of locations; generally if you can run spyder from the terminal, then you probably will find the correct python.

For future reference, what worked?

pythonstartup/default = True

or

From the command line run spyder --defaults.

Sorry, what helped is changing pythonstartup/default from False to True (pythonstartup/default = True) in spyder.ini file.

In your home directory find the .spyder2 directory. Look for the

pythonstartup/default

It is probably set to False. Set to True:

pythonstartup/default = True

I am getting the same error and i did what was mentioned over here to change the pythonstartup/default field but that field is already true andd it is still giving an error

Please help i am not getting what to do 

even the command line thing is not working
