问题描述

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，我得到了这个错误:

I'm working on an electron app that controls gulp tasks via gui. You click on a task and it runs. Pretty simple stuff. On macOS, when I run npm start it runs just fine, but when I package it with electron-packager, I get this error:

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'
            });
        }
    });
};

推荐答案

如果其他人遇到这个问题，答案是更正 $PATH.npm 上有一个包可以为你做这件事.

In case anyone else is running into this problem, the answer is to correct the $PATH. There is a package on npm that does this for you.
