Mackup 备份出错的临时解决办法

环境与前提

• 系统：macOS 10.13.6 (17G65)
• Python2.7 和 3.7 并存
• 通过 Homebrew 安装的 Mackup（ver 0.8.18)

报错内容

在终端中输入 mackup backup 后，报错如下

Traceback (most recent call last):
  File "/usr/local/Cellar/mackup/0.8.18/libexec/bin/mackup", line 9, in <module>
    load_entry_point('mackup==0.8.18', 'console_scripts', 'mackup')()
  File "/usr/local/Cellar/mackup/0.8.18/libexec/lib/python2.7/site-packages/mackup/main.py", line 65, in main
    app_db = ApplicationsDatabase()
  File "/usr/local/Cellar/mackup/0.8.18/libexec/lib/python2.7/site-packages/mackup/appsdb.py", line 34, in __init__
    if config.read(config_file):
  File "/Users/ouyang/Library/Python/2.7/lib/python/site-packages/backports/configparser/__init__.py", line 705, in read
    self._read(fp, filename)
  File "/Users/ouyang/Library/Python/2.7/lib/python/site-packages/backports/configparser/__init__.py", line 1109, in _read
    optname = self.optionxform(optname.rstrip())
UnicodeEncodeError: 'ascii' codec can't encode character u'\xdc' in position 28: ordinal not in range(128)

经过简单搜索，可以初步认定是因为 Python 版本兼容问题。

临时解决办法

参考来源：Problem right after installation #940

该文章中的解决办法是将 ubersicht.cfg 删除。为避免不可挽回的损失，我采取了下面的步骤和办法：

1. 从终端进入 /usr/local/Cellar/mackup/0.8.18/libexec/lib/python2.7/site-packages/mackup/applications/
2. 备份该文件 mv ubersicht.cfg ubersicht.cfg.bak

再次运行 mackup backup 后，可正常备份了。
