Dependencies

After reading some other issues, I found out that

spyder --reset

has solved the problem. But I am reporting the error anyway.

Thanks

@Cristianasp could you install for python 3.7 and check if the error persists?

[yomoko]

Whenever I deleted a block of code, my IDE crashed too.

@yomoko, please don't step into other people issues. That has nothing to do with this, so I'm going to hide your comment.

[ccordoba12]

@steff456, please take a look at this one. I think this happens when there's no shortcut to show help, i.e. instead of Ctrl+I people has nothing in preferences for it.

[dalthviz]

@steff456 @ccordoba12 seems like this related with:

• Not having a shortcut for inspect object (for the Editor and the Console) -> Ctrl+I
• Having the Help plugin in plain text mode

However, I not able to reproduce this since on Windows the Help plugin always shows the rich mode version even when I set rich_mode = False in the spyder.ini config file

[Cristianasp]

Forgot to mention that I got this error on Ubuntu.

Thanks @Cristianasp! I use Kubuntu, so I'll try to reproduce it.

[cpkc]

Gretings, I have the same issue only in portuguese, exactly in the plugin.py file
File ...."plugin.py", line 455, in show_intro_message
intro_message = (intro_message_eq + intro_message_common) % (
TypeError: not enough arguments for format string

I also tried other languages (English, French and Spanish) only potuguese presented the related issue.

After reset, spyder --reset, has partially resolved the issue.

[cpkc]

I find issue here:
%HOME%Anaconda3Libsite-packagesspyderlocalept_BRLC_MESSAGES file spyder.mo won't let spyder start in Brazilian Portuguese! At least in Windows 10 64.

[dalthviz]

Thanks @cpkc for the help finding out the cause of this! Probably the translation string in Portuguese has more % characters than the parameters that are actually passed!

[ccordoba12]

@cpkc, thanks a lot for finding the problem!!

@steff456, now you know how to fix this one.

[Cristianasp]

Interesting... My spyder language is English but it happens that I speak brazilian portuguese so it should be somewhere in the code of some configuration files!

[cpkc]

In addition, as experience, I have tried the file pt_BR spyder.mo from earlier release 3.3.6 (from zip source) in 4.1.1 Win64 10 release. This time spyder 4.1.1 started up without any crash with file spyder.mo from spyder 3.3.6 release. I made only a test, it is not a solution.

PS: I speak brazilian portuguese too.

@cpkc, thanks a lot for finding the problem!!

@steff456, now you know how to fix this one.

Dears @ccordoba12, @dalthviz and @Cristianasp

I think I found a solution (or the solution), line 3344 %HOME%Anaconda3Libsite-packagesspyderlocalept_BRLC_MESSAGESspyder.po :

"#: spyder/plugins/help/plugin.py:410
msgid "Here you can get help of any object by pressing %s in front of it, either on the Editor or the Console.%s"
msgstr "Aqui você pode obter ajuda de qualquer objeto pressionando %s na frente dele no Editor, ou %s na frente dele no Console.%s"" there is an extra %s beetween the words "ou" and "na". I have tried on a VM XUbuntu and msgfmt to compile .po file, worked fine as well.

[ccordoba12]

@cpkc, that's great!! I can understand the source of the problem now: it seems the Portuguese translator copied the translated string from spyder/plugins/help/plugin.py:414 to spyder/plugins/help/plugin.py:410, without noticing that the one in line 414 has an extra %s.

I did the fix myself here:

https://github.com/spyder-ide/spyder/blob/8a2cdde1795bbd87664489f1954ed2748729b3dc/spyder/locale/pt_BR/LC_MESSAGES/spyder.po#L3396-L3398

and it'll be part of our next version (4.1.3), to be released at the end of the month.

Thanks a lot @Cristianasp for reporting and @cpkc for finding the cause!!
