robotframework ride cannot be started with wxPython language problem

[Racheljia1989]

Operating system: windows 7 X86_64
**wxPython version **: 4.0.7.post2
**Python version **: 3.8.1
**robotframework-ride version **: 1.7.4
Description of the problem: I'm a tester and wantto use robotframework to write autotest cases.I installed python of version 3.8.7 and wxPython of version 4.0.7.post2 on windows platform.When I clicked the robotframework-ride button to start robotframework-ride,it failed to start because of wxPython.Failling tips came out as follows:

wx._core.wxAssertionError: C++ assertion "strcmp(setlocale(LC_ALL, NULL), "C") =
= 0" failed at ..\..\src\common\intl.cpp(1579) in wxLocale::GetInfo(): **You proba
bly called setlocale() directly instead of using wxLocale and now there is a mis
match between C/C++ and Windows locale.
Things are going to break, please only change locale by creating wxLocale object
s to avoid this!**
OnInit returned false, exiting...
Error in atexit._run_exitfuncs:
wx._core.wxAssertionError: C++ assertion "GetEventHandler() == this" failed at .
.\..\src\common\wincmn.cpp(478) in wxWindowBase::~wxWindowBase(): any pushed eve
nt handlers must have been removed

I've tried to change the language of wxPython in file application.py to chinese-simplified which was english in default,but it still failed.

class RIDE(wx.App):

    def __init__(self, path=None, updatecheck=True):
        self._initial_path = path
        self._updatecheck = updatecheck
        context.APP = self
        wx.App.__init__(self, redirect=False)

    def OnInit(self):
        # DEBUG To test RTL
        #self._initial_locale = wx.Locale(wx.LANGUAGE_ARABIC)
        #self._initial_locale = wx.Locale(wx.LANGUAGE_ENGLISH)
        self._initial_locale = wx.Locale(wx.LANGUAGE_CHINESE_SIMPLIFIED)
        # Needed for SetToolTipString to work
        wx.HelpProvider.Set(wx.SimpleHelpProvider())  # TODO adjust to wx versions 
        self.settings = RideSettings()
        librarydatabase.initialize_database()
        self.preferences = Preferences(self.settings)
        self.namespace = Namespace(self.settings)
        self._controller = Project(self.namespace, self.settings)
        self.frame = RideFrame(self, self._controller)
        self._editor_provider = EditorProvider()
        self._plugin_loader = PluginLoader(self, self._get_plugin_dirs(),
                                           coreplugins.get_core_plugins())

At last,I commented all the self.__initial_local code and the robotframework-ride could be started.However it’s also abnormal.

So,my question is how to solve the wxPython language problem completely,guys?

However it’s also abnormal.

In what way?

@Racheljia1989 We have a warning in RIDE's project that it is not compatible with Python 3.8. However, the current development version already have a fix for it, so you should try to install that version.

pip install -U https://github.com/robotframework/RIDE/archive/master.zip

@HelioGuilherme66 Thx a lot for ur answer,and I will try the new version later.

I also can't get RIDE to work. Similar error. Python 2.7.13 with wxPython 4.0.7.post2.

File "C:\Python27\lib\site-packages\robotide\ui\images.py", line 91, in _get_image
    img = wx.Image(path, wx.BITMAP_TYPE_PNG).ConvertToBitmap()
wxAssertionError: C++ assertion "strcmp(setlocale(LC_ALL, NULL), "C") == 0" failed at ..\..\src\common\intl.cpp(1579) in wxLocale::GetInfo(): You probably called setlocale() directly instead of using wxLocale and now there is a mismatch between C/C++ and Windows locale.
Things are going to break, please only change locale by creating wxLocale objects to avoid this!

Works with wxPython 4.0.3.

With wxPython 4.0.7 _initial_locale is set to a default locale with commit 6d77fcf. In the OnInit method calling wx.GetLocale() returns a valid "en_US" locale, which is the same object that is stored in self._initial_locale. But then this line tries to redefine self._initial_locale:

self._initial_locale = wx.Locale(wx.LANGUAGE_ENGLISH)

After this line calling wx.GetLocale() returns None. So somehow the act of changing _initial_locale is clearing the global locale. Possibly a race condition where the new locale is created, then the destructor of the initial locale (m_pOldLocale=null) clears the global locale?

There will be a new version of InitLocale() in wxPython 4.1.1 which might fix this. Can you try one of the latest snapshot builds to see if the problem is resolved? https://wxpython.org/Phoenix/snapshot-builds/
