运行Node脚本时，在当前shell上下文中更改工作目录 [英] Change working directory in my current shell context when running Node script

问题描述

我正在尝试从bin脚本运行时更改Node.js脚本的工作目录。我有以下内容：

I am trying to change the working directory of my Node.js script when it is run from a bin script. I have something like the following:

#!/usr/bin/env node
process.chdir('/Users')

当我用 ./ bin / nodefile运行此文件时，它退出，但当前shell上下文的工作目录没有改变。我也尝试了 shelljs ，但这也不起作用。

When I then run this file with ./bin/nodefile, it exits, but the working directory of the current shell context has not changed. I have also tried shelljs, but that does not work either.

做这个的最好方式是什么？我知道它正在运行，但它只是在一个单独的过程中。

What is the best way to do this? I understand it's working but it's just in a separate process.

推荐答案

更改目录的正确方法实际上是 process.chdir（目录）。以下是文档中的示例：

The correct way to change directories is actually with process.chdir(directory). Here's an example from the documentation:

console.log('Starting directory: ' + process.cwd());
try {
  process.chdir('/tmp');
  console.log('New directory: ' + process.cwd());
}
catch (err) {
  console.log('chdir: ' + err);
}

这在Node.js REPL中也是可测试的：

This is also testable in the Node.js REPL:

[monitor@s2 ~]$ node
> process.cwd()
'/home/monitor'
> process.chdir('../');
undefined
> process.cwd();
'/home'
