我从官方网站下载了Bootstrap源文件,并且在使用node's安装项目时遇到依赖冲突npm.我已经grunt 0.4.3在我的机器上安装了一些引导程序依赖项需要0.4.0和一些0.4.1.

该npm install -g grunt-cli命令没有任何问题执行.这是我执行npm install命令后得到的日志:

我正在尝试将spring-security-core插件安装到我的项目中,但似乎无法在任何存储库中找到插件文件.

我将此行添加到BuildConfig文件的插件部分:

    compile ':spring-security-core:2.0-RC2'

运行grails compile命令后,我遇到以下错误(缩短):

我需要提供一种在特定日期/时间重复执行操作的方法.基本上它应该像Cron一样工作,我正在考虑管理执行时间的方法.

一种解决方案可以是在每个作业/过程中运行循环,并不断检查(每分钟或每秒)当前时间是否是我们等待的时间.

另一种解决方案是通过等待下一次执行来与定时器一起工作.我们计算现在和下一个执行时间之间的差异,并将该延迟提供给计时器.但由于执行时间应该是可管理的,我们需要有一种方法来中断该计时器并创建一个新计时器,或者我们可以简单地杀死该进程并创建一个新进程.

有没有人对如何正确完成它有任何想法,或者它们是否是完成这一特定场景的任何库？

如何拆分二进制Erlang字符串将其数据视为UTF8字符？

假设我们有一个二进制文件,它应该分成两部分,第一部分应该包含前两个UTF8字符.这里有几个例子:
<<"????">>应该成为[<<"??">>, <<"??">>]

<<"?????">> 应该成为 [<<"??">>, <<"???">>]

如何在第一次出现特定字符序列之前匹配所有字符grep？我正在寻找一种在Linux环境中完成此任务的方法,因为我可能会遗漏一些关键的grep功能点,所以我们也欢迎使用awkir 解决方案的想法sed.

该问题还涉及在单行中单独匹配所有出现的模式.

为了更好地了解情况,我们假设我们有一个命令
echo "word word" | grep -o 'w.*rd'

看起来直到序列的最后一次出现才匹配rd,所以当我们运行它时,我们得到:
word word

我真正想要的是:

word
word
