我在創作一個Grunt任務時遇到了一些困難。我試圖執行npm install,然後是bower install,然後是一個grunt中心目標(爲多個子項目觸發構建命令)。節點JS - child_process spawn('npm install')在Grunt任務中導致ENOENT錯誤
我遇到的問題與child_process謊言。我得到重生ENOENT錯誤,如果我在繁重的任務中運行以下命令,與故宮安裝,因此目前註釋掉產卵命令:
var path = require('path'),
projectPath = path.resolve(process.cwd(), this.data.activity);
grunt.log.debug('project path computed as: ', projectPath);
process.chdir(projectPath);
console.log('current dir is: ', process.cwd());
console.log('EVN is: ', process.env);
var spawnProcess = spawn('ls');
// var spawnProcess = spawn('npm install');
spawnProcess.stdout.on('data', function (data) {
console.log('' + data);
});
spawnProcess.stderr.on('data', function(data) {
console.log('something went wrong installing deps for ' + path + '. Error: ', data);
});
spawnProcess.on('close', function (exitCode) {
console.log('ls has finished with Exit Code: ' + exitCode);
});
當前的代碼(除ls而不是NPM安裝)結果:
running "install:projects" (install) task[D] Task source: /Users/zedd45/proj/Gruntfile.js
Verifying property install.projects exists in config...OK
File: [no files]
[D] project path computed as: /Users/zedd45/proj/activity/web/client
current dir is: /Users/zedd45/proj/activity/web/client
EVN (abbreviated) is: {
TERM_PROGRAM: 'iTerm.app',
SHELL: '/bin/bash',
PWD: '/Users/zedd45/proj',
...
OLDPWD: '/Users/zedd45/proj/activity/web/client',
_: '/usr/local/bin/grunt' }
GruntFile.js
bower.json
package.json

ls has finished with Exit Code: 0
,但如果我改變「LS」到「故宮安裝」我得到,而不是 ``致命錯誤:產卵ENOENT
立即ENV打印以下。
我已經嘗試chmod 777該目錄,這似乎沒有幫助。
我也曾嘗試:
// var spawnProcess = spawn('npm install', {'cwd': projectPath});
和
// var spawnProcess = spawn('npm install', [], {'cwd': projectPath});
前者導致
Warning: Object # has no method 'slice' Use --force to continue.
後仍導致ENOENT錯誤。
任何幫助確切地說這個ENOENT錯誤可能會幫助很多;我沒有太多的成功谷歌搜索它與child process API docs
那完美。我無法相信一旦你提供瞭解決方案,解決方案是多麼的簡單/明顯,或者它難以避免。非常感謝! – zedd45

嗯,這不適用於我。仍然得到一個spawnSync npm ENOENT(是的,我正在使用同步版本) – ianbeks
