我正在尝试exuberant-ctags
在 Linux Mint 上安装该软件包。为此,我跑了:
$ sudo apt-get install exuberant-ctags

update-alternatives: using /usr/bin/ctags-exuberant to provide /usr/bin/ctags (ctags) in auto mode
最后一行建议ctags-exuberant
使用 来代替ctags
。
但是,当我重新启动 bash 并运行时,ctags -e
出现错误:
ctags: invalid option -- 'e'
虽然该-e
选项在exuberant-ctags
.
怎么还没exuberant-ctags
换ctags
?
$ command -v ctags
/usr/local/bin/ctags
这不是我想要的
$ ls -l /usr/bin/ctags
lrwxrwxrwx 1 root root 23 Dec 28 2015 /usr/bin/ctags -> /etc/alternatives/ctags
$ ls -l /etc/alternatives/ctags
lrwxrwxrwx 1 root root 24 Aug 9 21:22 /etc/alternatives/ctags -> /usr/bin/ctags-exuberant
$ ctags --version

您的安装可能只是exuberant-ctags
作为替代选项添加的。
/usr/bin/update-alternatives --display ctags
如果它指向错误的版本,您可以手动设置替代版本
sudo /usr/bin/update-alternatives --set ctags /usr/bin/ctags-exuberant
但是,在您的情况下(根据您的问题更新),在打包版本之前,您的 PATH ( )中ctags
有一个非打包版本,因此首先调用它。/usr/local/bin/ctags
ctags-exuberant
alternatives
您需要删除该版本,修改您的版本$PATH
或将符号链接添加到/usr/bin/ctags
路径中的较早位置(也许$HOME/bin
),以便您运行您想要运行的版本。
