Question

一天的美好时光！我尝试升级Ubuntu 14.04，但出现以下错误：

ub14:~$ do-release-upgrade -d
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [836 B]                                           
Get:2 Upgrade tool [1 265 kB]

Traceback (most recent call last):

    sys.exit(main())

    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: __call__() missing 1 required positional argument: 'name'

所有需要的东西都已完成：

ub14:~$ sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade
ub14:~$ sudo apt-get install update-manager-core

＆lt; - 好了。

问题的最可能原因：一旦我尝试升级Ubuntu 14.04，但忘记在电池完全放电之前重启系统。从那时起，每次尝试更新时都会出现TypeError: __call__() missing 1 required positional argument: 'name'。从GUI更新也是不可能的 - 只需关闭按下＆＃34;升级＆＃34; - 按钮的窗口，就可以了。可能任何人都已经解决了同样的问题，这个信息可能很有用。

有没有办法在没有任何副作用的情况下解决问题（我知道将MARKER_EXPR()更改为MARKER_EXPR("")的技巧，但没有关于副作用的信息在升级过程中或之后）？提前谢谢！

我遇到了同样的问题。执行sudo pip uninstall pyparsing然后sudo pip install pyparsing为我解决了这个问题。
