python - Mercurial 由于 qct 扩展而崩溃 - 我尚未启用该扩展

Question

在我的一个 Mercurial 存储库上，该存储库曾经可以工作，当我运行 hg status 时，我得到:

** Unknown exception encountered with possibly-broken third-party extension qct
** which supports versions unknown of Mercurial.
** Please disable qct and try your action again.
** If that fixes the bug please report it to the extension author.
** Python 2.7.12 (default, Sep 29 2016, 13:30:34) [GCC 6.2.1 20160916 (Red Hat 6.2.1-2)]
** Mercurial Distributed SCM (version 3.7.3)
** Extensions loaded: qct, color, pager, extdiff, hgk, graphlog, hggit

现在，我还没有启用 qct 扩展，并且在我的 .hgrc 和存储库中的 .hg/hgrc 中都找不到它。这里发生了什么？我该如何解决/规避这个问题？

可能存在系统范围的配置文件。来自hg help hgrc:

On Unix, the following files are consulted:

• "/.hg/hgrc" (per-repository)
• "$HOME/.hgrc" (per-user)
• "/etc/mercurial/hgrc" (per-installation)
• "/etc/mercurial/hgrc.d/*.rc" (per-installation)
• "/etc/mercurial/hgrc" (per-system)
• "/etc/mercurial/hgrc.d/*.rc" (per-system)
• "/default.d/*.rc" (defaults)

当用户配置文件覆盖系统范围的配置文件时，您可以在本地禁用它。引用自https://www.mercurial-scm.org/wiki/UsingExtensions :

To explicitly disable an extension enabled in an hgrc of broader scope, prepend its path with !:

[extensions]

# disabling extension bar residing in /path/to/extension/bar.py

bar = !/path/to/extension/bar.py

# ditto, but no path was supplied for extension baz

baz = !
