Install

npm install用法npm install是Node.js中的一个命令，用于安装和管理Node.js模块。

它可以完成以下几个任务：①安装模块：使用npm install <package> 命令可以安装指定的模块。

例如，如果要安装lodash模块，可以使用npm install lodash 命令。

使用npm install <package>@<version> 命令可以安装指定版本的模块，将<version> 替换为具体的版本号。

②安装模块并保存到package.json 文件中：使用npm install <package> --save 命令可以将安装的模块信息保存到package.json 文件中，方便项目管理。

③升级模块：使用npm update <package> 命令可以升级指定的模块。

例如，如果要升级lodash模块，可以使用npm update lodash 命令。

④卸载模块：使用npm uninstall <package> 命令可以卸载指定的模块。

例如，如果要卸载lodash模块，可以使用npm uninstall lodash 命令。

⑤安装开发依赖模块：使用npm install <package> --save-dev 命令可以将安装的模块信息保存到package.json 文件的devDependencies 中，用于开发环境中的依赖管理。

例如，如果要安装mocha模块，可以使用npm install mocha --save-dev 命令。

⑥全局安装模块：使用npm install -g <package> 命令可以全局安装指定的模块。

例如，如果要全局安装nodemon模块，可以使用npm install -g nodemon 命令。

adb常用的几个命令 adbinstall ADB（Android Debug Bridge）是Android开发工具包（SDK）中的一个命令行工具，用于与Android设备进行通信和调试。

ADB常用的几个命令如下：1. adb devices：用于列出当前连接的Android设备列表。

当设备连接到计算机时，可以使用该命令来验证设备是否成功连接。

2. adb shell：用于在设备的shell环境下执行命令。

通过该命令可以获取设备的root权限，以便执行一些需要root权限的操作。

3. adb install：用于将应用程序安装到连接的Android设备上。

命令格式为“adb install <path_to_apk_file>”，其中<path_to_apk_file>为待安装的APK文件的路径。

4. adb uninstall：用于从连接的Android设备中卸载应用程序。

命令格式为“adb uninstall <package_name>”，其中<package_name>为待卸载应用程序的包名。

5. adb push：用于将文件从计算机复制到连接的Android设备中。

命令格式为“adb push <local_file> <device_path>”，其中<local_file>为计算机上的文件路径，<device_path>为目标设备中的路径。

6. adb pull：用于将文件从连接的Android设备中复制到计算机上。

命令格式为“adb pull <device_file> <local_path>”，其中<device_file>为设备上的文件路径，<local_path>为目标计算机上的路径。

7. adb logcat：用于查看设备的日志信息。

在实际使用过程中，我们可以通过添加不同的参数来实现不同的功能。

下面我们将详细介绍npm install 常见参数及其作用。

1.npm install 命令简介pm install 命令用于安装项目所需的依赖项。

它会读取package.json 文件中的依赖项信息，然后从npm registry 下载相应的软件包并安装到项目中。

此外，npm install 还可以接收一系列参数，以实现更丰富的功能。

2.常见参数及其作用以下是一些常见的npm install 参数及其作用：a.-g：全局安装使用-g 参数可以将依赖项安装到全局作用域，而非项目内部。

这使得该依赖项可以在任何Node.js 项目中使用，而不仅仅是当前项目。

例如：`npm install -g express`。

b.-o：安装最新版使用-o 参数可以安装依赖项的最新版本。

"make install"是一条在Unix和Linux系统中常用的命令，主要用于安装已经编译好的程序。

具体来说，这条命令将复制编译生成的文件树中的文件到指定的位置。

在使用"make install"之前，通常需要先进行编译，也就是执行"make"命令。

如果编译过程中出现错误，需要记下错误代码并尝试解决，这可能包括向开发者提交bug报告，或者检查系统是否缺少某些依赖库。

一旦编译成功，"make install"命令就可以将编译好的程序安装到系统中。

请注意，这个过程通常需要具有root权限，因为安装过程可能涉及到向系统写入文件。

此外，还有一些与"make install"相关的命令，如"make uninstall"，用于卸载已经安装的程序；"make clean"，用于删除由"make"命令产生的文件；以及"make distclean"，用于删除由"./configure"产生的文件等。

pip install的用法pip是Python的包管理器，用于安装和管理Python软件包。

它是Python 官方推荐的包管理工具，能够帮助开发者快速、方便地获取和安装第三方库。

本文将介绍pip install的用法，并且详细说明每个步骤的操作过程。

一、安装pip要使用pip，首先需要安装它。

根据操作系统的不同，可以选择不同的安装方式。

下面分别介绍Windows、Linux和Mac OS中安装pip的方法。

1. 在Windows上安装pip在Windows上安装pip的方法有两种：一是使用Python自带的安装程序，二是使用官方提供的get-pip.py脚本文件。

a. 使用Python自带的安装程序Python 2.7.9及之后的版本以及Python 3.4及之后的版本已经内置了pip，因此只需确保Python已正确安装即可。

b. 使用get-pip.py脚本文件首先，需要下载get-pip.py脚本文件，可以从python get-pip.py2. 在Linux上安装pip在Linux系统中，可以通过包管理器来安装pip。

下面分别介绍在Debian 和Red Hat系列的Linux发行版上安装pip的方法。

a. 在Debian系列中安装pip使用以下命令安装pip：sudo apt-get install python-pipb. 在Red Hat系列中安装pip使用以下命令安装pip：sudo yum install python-pip3. 在Mac OS上安装pip在Mac OS中安装pip与在Linux系统中安装pip类似。

首先，需要打开终端，然后使用以下命令安装pip：sudo easy_install pip二、使用pip安装完pip后，就可以开始使用它来安装第三方库了。

下面将详细介绍pip install的用法，并分步骤进行操作。

1. 查找包在安装包之前，可以使用pip search命令来查找特定的包。

--azure云背景没有自动发送email短信报警功能azure云上的linux vm没有自动发送email短信报警服务，所以准备用开源的zabbix来实现，原来用nagios，但是听说zabbix有自动识别的功能，不需要nagios配置那么多东西，zabbix更加人性化，所以准备用用zabbix。

1，准备安装环境参考安装文档地址：https:///documentation/3.0/manual/installation/install_from_packages#red_ha t_enterprise_linuxcentos清空原来的缓存：安装新的zabbix yum源，由于版本更新，这个连接地址可能会失效，需要自己去zabbix官安装文档地址：https:///documentation/3.0/下载地址：/zabbix/3.0/rhel/6/x86_64/2，Yum安装开始yum安装zabbix-server：PS：犹豫rhel系统（centos系统不存在问题）缺少php-bcmath和php-mbstring这两个包，会导致Web页面的安装提示缺少组件，所以可以在centos源中下载这2个包安装即可。

3，准备mysql数据库安装mysql数据库：/mchdba/article/details/51138063创建zabbix的数据库：PS：字符集要设置为utf8mb4，防止界面切换到中文的时候乱码。

导入create.sql.gz文件，建立zabbix-server的数据库（ps，以前的版本可能叫啥schema.sql 之类的）：4，开始配置数据库5，启动zabbix进程服务6，安装apache7，关闭selinux安装web源：8，Zabbix管理界面打开失败。

如1.png所示：D:\study\zabbix\1.png问题来了，rpm包安装方式中的zabbix web打开的工程在哪里？是如何和httpd配合一起工作的？官方rpm安装文档里面没有相应的记录，或者在别的地方有但是我没有找到它吧，不过这个rpm的方式安装，只能暂时搁浅放弃了，等待下次有空继续研究下其中流程和原理。
