示例1: spawn
import * as spawn from 'cross-spawn';
import * as cp from 'child_process';
const p1: cp.ChildProcess = spawn('my-cmd', ['foo', 'bar']);
const pw: cp.ChildProcess = spawn('my-cmd', ['foo', 'bar'], {env: process.env});
pw.on('error', (err: Error) => {
console.log(err);
});
const r1: Error = spawn.sync('foo').error;
const r2: string[] = spawn.sync('foo').output;
const r3: Buffer = spawn.sync('foo').stdout;
const r4: Buffer = spawn.sync('foo').stderr;
const r5: number = spawn.sync('foo').status;
const r6: string = spawn.sync('foo').signal;
const r7: string = spawn.sync('foo', {encoding: 'utf8'}).stdout;
spawn.sync('foo', ['bar']);
spawn.sync('foo', ['bar'], {stdio: 'inherit'});
示例2: Promise
new Promise((resolve, reject) => {
const npm = spawn('npm', ['--prefix', cwd, 'install'], {
stdio: 'inherit',
});
npm.on('close', resolve);
npm.on('error', reject);
});示例3: Promise
return new Promise((resolve, reject) => {

cwd: vscode.workspace.rootPath,
detached: !(os.platform() === 'win32')
});
nreplProcess.stdout.addListener('data', data => {
const nreplConnectionMatch = data.toString().match(R_NREPL_CONNECTION_INFO);

const message = `nREPL exited with code ${code}`
nreplChannel.appendLine(message);
// Bring the output channel to the foreground so that the user can
// use the output to debug the problem.
nreplChannel.show();
return reject({ nreplError: message});
});
