如何从命令行运行不带“节点"字样的Node.js程序 [英] How to run Node.js program from command line without word 'node'

问题描述

我正在开发Node.js程序包，其中包括一个命令行实用程序.现在， alacon.js 位于包的根目录中.要运行此实用程序，我必须在实用程序名称之前使用单词 node ，例如:

I am developing the Node.js package, which includes a command-line utility. Now alacon.js is located in the root of the package. To run this utility I have to use word node before the name of utility, like:

 node alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

您能帮我吗，我应该将包装中的内容更改为:

Could you help me, what should I change in the package to:

1.要运行不带 node 字样的实用程序，例如:

1.To run this utility without node word, like:

 alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

2.要全局安装此软件包并在计算机上的任何地方使用该实用工具，

2.To install this package globally and use the utility everywhere on computer:

 npm install -g alasql
 alacon 'SELECT 2*2'

换句话说，如何使用命令行程序创建实用程序，如Jison，Gulp和其他Node.js类似包.

In other words, how to create utility like Jison, Gulp and other Node.js similar packages with command-line programs.

我已经在文件的顶部添加了#！/usr/bin/env节点行，但是不幸的是没有达到预期的效果.

I already add the #!/usr/bin/env node line to the top of the file, but unfortunately have no desired effect.

谢谢！

推荐答案

您将需要使脚本可执行 chmod a + x alacon .

You will need to make the script executable chmod a+x alacon.

然后，您应该可以运行./alacon'SELECT * FROM CSV("mydata.csv")ORDER BY 2'

Then you should be able to run ./alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

如果您希望在不使用 ./的情况下调用脚本，则需要将其移动(或符号链接)到/usr/bin.

If you wish to invoke the script without ./ then you will need to move it (or symlink it) to /usr/bin.

或者-您可以创建一个别名: alias alacon ="node alacon"

Alternatively - you could create an alias: alias alacon="node alacon"
