我如何调试“错误:产卵ENOENT”在node.js?

当我得到以下错误:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34)

我该采取什么程序来修理呢?

当前回答

简单地添加shell: true选项解决了我的问题:

不正确的:

const { spawn } = require('child_process');
const child = spawn('dir');

正确的:

const { spawn } = require('child_process');
const child = spawn('dir', [], {shell: true});

其他回答

试了所有的都没用，我的系统有不同的问题。

我的解决方案是运行命令: C:\Program Files\git\bin\bash.exe

我也遇到了同样的问题，但我找到了一个简单的解决方法。如果程序已经被用户添加到PATH(例如，正常的系统命令工作)，它似乎是spawn()错误。

要解决这个问题，你可以使用which模块(npm install——save which):

// Require which and child_process
const which = require('which');
const spawn = require('child_process').spawn;
// Find npm in PATH
const npm = which.sync('npm');
// Execute
const noErrorSpawn = spawn(npm, ['install']);

正如@DanielImfeld指出的那样，如果你在选项中指定了“cwd”，但是给定的目录不存在，ENOENT将被抛出。

对于Windows上的ENOENT, https://github.com/nodejs/node-v0.x-archive/issues/2318#issuecomment-249355505修复它。

如更换产卵(npm, [' v '], {stdio:“继承”}):

对于所有node.js版本: 产卵(/ ^赢/ test (process.platform) ?npm。Cmd ': 'npm'， ['-v']， {stdio: 'inherit'}) 对于node.js 5。X及以后: 产卵(npm, [' v '], {stdio:“继承”,外壳:真})
