仅在开发人员计算机上运行gettext.py时接收ioerror

在开发人员机器上运行由.net应用程序调用的ironpython应用程序时,我们从ironpython获得错误ioerror。在跟踪错误时,我们看到它来自翻译函数中的gettext.py。它似乎与default_LocaleDir变量有关,该变量显示:“file:///c:/windows/microsoft.net/assembly/gac_MSIL/ironpython/v4.0_2.7.9.0_7f709c5b713576e1/ironpython.dll\share\locale”

该应用程序在我们的测试和生产服务器上运行得非常好,因此看起来像是配置问题。

我们试图将pythonpath环境变量设置为c:\ program files\ironpython 27,这是ironpython软件下载到的位置,但没有什么不同。

def translation(domain, localedir=None, languages=None,
                class_=None, fallback=False, codeset=None):
    if class_ is None:
        class_ = GNUTranslations
    mofiles = find(domain, localedir, languages, all=1)
    if not mofiles:
        if fallback:
            return NullTranslations()
        raise IOError(ENOENT, 'No translation file found for domain', domain)
    # Avoid opening, reading, and parsing the .mo file after it's been done
    # once.
    result = None
    for mofile in mofiles:
        key = (class_, os.path.abspath(mofile))
        t = _translations.get(key)
        if t is None:
            with open(mofile, 'rb') as fp:
                t = _translations.setdefault(key, class_(fp))
        # Copy the translation object to allow setting fallbacks and
        # output charset. All other instance data is shared with the
        # cached object.
        t = copy.copy(t)
        if codeset:
            t.set_output_charset(codeset)
        if result is None:
            result = t
        else:
            result.add_fallback(t)
    return result

当查看结果时,它显示为空。

我们没有对gettext.py或任何标准的python代码做任何更改。
