Question

我已经为myqsl数据库编写了一个接口，该接口在出现错误的情况下（好像数据库处于脱机状态一样）会通过引发我的自定义错误来处理它，以便我知道出了什么问题。我对此感到满意，并决定准备将其转换为exe，并使用py2exe进行了此操作。这失败了，经过一番研究，我发现它不再起作用了，所以我降级到python 3.4。现在可以进行转换，但是转换后的程序不再处理错误。

我检查了我是否具有正确的mysql连接器，然后重新下载了相同的连接器，以便将其包含在内，因为我正在处理的错误通常是mysql.connector.Error。

原始程序中的错误处理：

import myqsl.connector as mariadb

try:
    mariadb_connection = mariadb.connect(user='root', password='', database='marsmenagerie')
    cursor = mariadb_connection.cursor()
except mariadb.Error:
    clearscreen()
    print("Failed to connect to Database. (Error: 2475JWRT), Contact Censored")
    print("===========================")
    PAUSE()
    exit()

如果应引发此错误，则转换后的程序会产生错误：

我知道，它很长。我正在尝试使其尽可能短，但是我不想保留可能相关的信息。也许是我制作MCVE的最大问题。

我希望它会引起我编写的错误。但是，它只会引发上面显示的错误。在数据库处于活动状态下运行时，程序可以正常运行。

Answer 1

好吧。我已经解决了！问题是py2exe不会复制标准mysql错误的eng本地化，至少在这种情况下不会复制。您可以在以下错误的这一行中找到证据：

ImportError: No module named 'mysql.connector.locales.eng'

此问题以前似乎已经存在，因此已解决。（ImportError: No localization support for language 'eng' in python）在此站点的帮助下，我手动将eng本地化添加到library.zip文件： http://pydoc.net/mysql-connector-python/2.0.2/

现在它像梦一样运作。

Answer 2

此问题的答案为here。我在这里再次提到它，以防链接不起作用。此问题与@That One提到的问题相同，其中 py2exe 或 pyInstaller 不会将模块文件 mysql.connector.locales.eng 复制到 exe 。为此，我们只需将代码部分放入

from mysql.connector.locales.eng import client_error

在我们的python脚本中。这样， py2exe 或 pyInstaller 会将丢失的文件复制到 exe 。

使用py2exe转换为exe后，Python程序无法处理错误
