我是新来的composer,我想知道的区别require和require-dev.作曲家网站没有很好地解释这两者之间的区别.
我没有得到的部分Lists packages required for developing this package, or running tests, etc.来自Composer Official Docs.
安装java我总是使用终端的经典方式.我想手动安装java.我将JDK的文件夹放在桌面上,然后设置环境变量(PATH,CLASSPATH和JAVA_HOME).从终端,如果我输入java -version我打印
foralobo@ubuntu-vincy:~$ java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
但是当我尝试安装eclipse或netbeans时,系统警告说机器上没有安装java.
完成手动安装缺少什么？(Ubuntu 13.04)
我常用的是:
yum install git
它没有在我的CentOS 6上安装最新版本的git.如何更新到CentOS 6的最新版本的git？该解决方案适用于较新版本的CentOS,如CentOS 7.
我正在尝试在使用OpenSSL 1.0.0的Ubuntu 10.04 LTS上构建一些代码.当我运行make时,它使用"-lssl"选项调用g ++.来源包括:
#include <openssl/bio.h>
#include <openssl/buffer.h>
#include <openssl/des.h>
#include <openssl/evp.h>
#include <openssl/pem.h>
#include <openssl/rsa.h>
我跑了:
$ sudo apt-get install openssl

openssl is already the newest version.

但我想openssl包不包含库.我在make上遇到这些错误:

gem install pg 给出了这个错误
