我正在开发一个通过 gui 控制 gulp 任务的电子应用程序。您单击一个任务，它就会运行。很简单的东西。在 macOS 上，当我运行 npm start 时它运行得很好，但是当我用电子打包器打包它时，我收到了这个错误：
Uncaught Exception:
Error: spawn gulp ENOENT
at exports._errnoException (util.js:1022:11)
at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)
at onErrorNT (internal/child_process.js:359:16)
at _combinedTickCallback (internal/process/next_tick.js:74:11)
at process._tickCallback (internal/process/next_tick.js:98:9)
这是代码：
exports.runTask = (taskName, projPath) => {
const cp = spawn('gulp', [ taskName ], {cwd: projPath});
cp.stdout.setEncoding('utf8');
cp.stdout.on('data', data => {
console.log(data);
mainWindow.webContents.send('task-console-data', data);
});
cp.stderr.setEncoding('utf8');
cp.stderr.on('data', data => {
console.error(data);
displayNotification({text: `[error] ${data}`});
mainWindow.webContents.send('task-console-data', `[error] ${data}`);
});
cp.on('exit', code => {
if (code === 0) {
displayNotification({
title: 'gulp',
subtitle: 'Finished running tasks'
});
} else if ( !code || code === null ) {
return;
} else {
console.error(`Exited with error code ${code}`);
displayNotification({
title: 'gulp',
subtitle: `Exited with error code ${code}`,
sound: 'Basso'
});
}
});
};
