Python 程序在使用 py2exe 转换为 exe 后不处理错误
Python program doesn't handle error's after conversion to exe using py2exe
我已经为 myqsl 数据库编写了一个接口，如果出现错误，就像数据库离线一样，它会通过引发我的自定义错误来处理它，这样我就知道出了什么问题。我对此很满意，并决定可以将其转换为 exe，并使用 py2exe 完成了此操作。这失败了，经过一些研究，我发现它不再有效，所以我降级到 python 3.4。现在它转换了，但是转换后的程序不再处理错误。
我检查了我是否有正确的 mysql 连接器，并重新下载了完全相同的连接器，这样它就会被包括在内，因为我正在处理的错误通常是 mysql.connector.Error。
原程序错误处理：
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()
如果应该引发此错误，转换后的程序会创建错误：

我知道，它很长。我尽量保持简短，但我不想隐瞒可能相关的信息。也许是我制作 MCVE 最大的问题。
我原以为它会引发我编写的错误。但是它只是引发了上面显示的错误。当 运行 数据库处于活动状态时，程序 运行 没问题。
嗯。我已经解决了！问题是标准 mysql 错误的 eng 本地化不会被 py2exe 复制，至少在这种情况下不会。您可以在错误的这一行找到证据：
ImportError: No module named 'mysql.connector.locales.eng'
这个问题似乎以前就存在过，因此有一个修复。 (ImportError: No localization support for language 'eng' in python) 在本网站的帮助下，我手动将 eng 本地化添加到 library.zip 文件中：
http://pydoc.net/mysql-connector-python/2.0.2/
现在一切如梦如幻。
此问题在 中有答案。我在这里再次提到它以防 link 不起作用。该问题与@That One 提到的相同，其中 py2exe 或 pyInstaller 不复制模块文件 mysql.connector.locales.eng 到 exe。为此，我们可以只放代码部分，
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.
