node.js同步执行系统命令 [英] node.js execute system command synchronously

问题描述

我需要 node.js 功能

  result = execSync（'node -v' ）; 
 

将同步执行给定的命令行并返回所有stdout通过该命令文本。

ps。同步错误。我知道。只供个人使用。

UPDATE

现在我们有mgutz的解决方案，它给我们退出代码，但不是stdout！仍在等待更准确的答案。

UPDATE

mgutz 更新了他的答案，解决方案在这里:)

同样， dgo.a 提到，有独立模块exec-sync

UPDATE 2014-07-30

ShellJS lib到达。现在考虑这是最好的选择。

UPDATE 2015-02-10 p>

到最后！ NodeJS 0.12本身支持 execSync 。

官方文档

解决方案

NodeJS 0.12和IO.js 1.10现在支持 execSync ：

child_process.execSync（command [，options]）＃

现在可以直接执行：

  const execSync = require（'child_process'）。execSync; 
 code = execSync（'node -v'）; 
  

它会做你期望的。 （默认为将io结果传递给父进程）。请注意，您现在还可以 spawnSync 。

I need in node.js function

result = execSync('node -v');

that will synchronously execute the given command line and return all stdout'ed by that command text.

ps. Sync is wrong. I know. Just for personal use.

UPDATE

Now we have mgutz's solution which gives us exit code, but not stdout! Still waiting for a more precise answer.

UPDATE

mgutz updated his answer and the solution is here :)
Also, as dgo.a mentioned, there is stand-alone module exec-sync

UPDATE 2014-07-30

ShellJS lib arrived. Consider this is the best choice for now.

UPDATE 2015-02-10

AT LAST! NodeJS 0.12 supports execSync natively.
See official docs

解决方案

NodeJS 0.12 and IO.js 1.10 now support execSync:

child_process.execSync(command[, options])#

You can now directly do this:

const execSync = require('child_process').execSync;
code = execSync('node -v');

and it'll do what you expect. (Defaults to pipe the io results to the parent process). Note that you can also spawnSync now.
