Python Spyder reset

Question

I am using spyder and it got crashed so I tried to fix it but couldn't do it.

So I finally uninstall the spyder and reinstalled it again but I am getting the same problem again.

When I open the Spyder I am getting the below message:

Spyder crashed during last session

If Spyder does not start at all and before submitting a bug report, please try to reset setting to defaults by running Spyder with the command line option '--reset:

python spyder --reset

I tried running the code in the command prompt window as the command was displayed in the message :

python spyder --reset

But I am getting another error telling:

python: can't open file 'spyder': [Errno 2] No such file or directory

I added the path to Spyder several times but failed. I am using the Windows 32 bit system and the crash repost of the Spyder looks like this:

Traceback (most recent call last):

  File "C:\Python27\lib\site-packages\spyderlib\spyder.py", line 1547, in main

    mainwindow = run_spyder(app, options)

    if rawhistory[1] != self.INITHISTORY[1]:

Any help will be appreciated.

Python doesn't search spyder in the PATH for example"

c:\some\dir> python some_file

Here python tries to read c:\some\dir\some_file file i.e., it looks into a current directory for some_file file.

c:\some\dir> python another_dir\some_file

Here python tries to read c:\some\dir\another_dir\some_file file i.e., it looks in the another_dir directory for some_file file.

c:\some\dir> python C:\path\to\some_file

Here python tries to read C:\path\to\some_file file i.e., it looks in the C:\path\to directory.

If you observe in the message the Spyder is telling to run the command:

python spyder --reset

Because it is assuming that you are present in the spyder script lives. It also works from the source script directory.

When you install you should create Spyder to Spyder.bat files. In case Spyder.bat is present then run as it is

c:\any\dir> spyder

Instead of python spyder --reset you can try:

c:\any\dir> spyder --reset

At last, you can run the command:

python -c "from spyderlib.spyder import main; main()" --reset

I hope this will help you.
