我正在尝试使用crontab执行以下shell脚本:
#!/bin/sh
cd /mnt/voylla-production/current
bundle exec rake maintenance:last_2_days_orders
bundle exec rake maintenance:send_last_2_days_payment_dropouts
crontab条目是
0 16 * * * /mnt/voylla-production/releases/20131031003111/voylla_scripts/cj_4pm.sh
我在邮件中收到以下错误消息:
/mnt/voylla-staging/current/voylla_scripts/cj_4pm.sh: line 3: bundle: command not found
/mnt/voylla-staging/current/voylla_scripts/cj_4pm.sh: line 4: bundle: command not found
我手动运行命令时没有收到错误.不知道这里发生了什么.请有人指出.
谢谢
我是第一次使用AWS.我创建了一个EC2实例.我选择"启动配置"作为Ubuntu Server 12.04.1 LTS.
但在启动之后,该州被"终止"了.
以下内容如下所示:
State Transition Reason: Server.InternalError: Internal error on launch
可能是它背后的原因以及如何运行实例？
我有两本词典.我想合并这些字典,使得结果字典中任何键的值是用于合并的两个字典中键的值的最小值.
h1 = {"a":3, "b":5, "c":2}
h2 = {"a":1, "c":5, "d":10}
result = merge(h1, h2) = {"a":1, "b":5, "c":2, "d":10}
有一个很酷的衬垫吗？如果没有,最优雅的方式是什么？
我是第一次使用PHP.我正在使用php示例在ebay沙箱上上传图片.我在运行PHP文件时收到以下错误:

我正在努力spark 1.5.2.我理解批处理间隔是什么,基本上是处理部分应该从接收器接收的数据开始的间隔.但我不明白是什么spark.streaming.receiver.maxRate.从一些研究来看,它显然是一个重要的参数.
让我们考虑一个场景.我的批处理间隔设置为60秒.并spark.streaming.receiver.maxRate设置为60*1000.如果由于某些临时负载而在60秒内获得60*2000记录该怎么办？会发生什么？是否会删除额外的60*1000记录？或者在批处理间隔期间处理会发生两次？

但我无法弄清楚出了什么问题.已经花了一个多小时才看到它,但没有运气.以下是详细信息:

# …我遇到了几种使用WordNet结构和层次结构测量语义相似性的方法,例如Jiang和Conrath measure(JNC),Resnik measure(RES),Lin measure(LIN)等.
使用NLTK测量它们的方式是:
sim2=wn.jcn_similarity(entry1,entry2,brown_ic)
sim3=entry1.res_similarity(entry2, brown_ic)
sim4=entry1.lin_similarity(entry2,brown_ic)
如果WordNet是计算语义相似度的基础,那么Brown Corpus的用途是什么？
以下是crontab中的条目:
MAILTO=abc@gmail.com
45 14 * * * /home/user/simple.sh
我也完成chmod +x了simple.sh但是crontab没有运行,它甚至没有发送电子邮件.
pgrep cron显示Id.我也试过弹跳crond.但没有运气!有人可以指出这里的错误
simple.sh脚本是:
#! /bin/bash
echo hello
