javascript - fork 进程找不到模块

Question

我有以下命令:

var fk = cp.fork('./client/processes/getClipboardImage.js',[],{cwd: __dirname + '/../../'});

然后运行:

"use strict";
const electron_1 = require('electron');
var base64Image = electron_1.clipboard.readImage().toDataURL();
process.emit('got-string', base64Image);

我不知道为什么，但我收到一条错误消息:

Cannot find module 'electron'

初始化 fork 的文件确实可以访问 Electron，那么为什么不进行 fork 处理呢？

执行文件位于controllers中，它运行utils/Workpace.js中的一个方法，并且该方法创建fork。

client/controllers/index.js

import { Workspace } from '../../client/utils/Workspace';
import { globals } from '../../client/utils/global';

ipcRenderer.on('workspace.paste', e => {
    if (globals.activeWorkspace) {
        globals.activeWorkspace.pasteToLayer();
    }
});

client/utils/Workspace.js

import cp = require('child_process');

export class Workspace {
    public pasteToLayer(/*image: Electron.NativeImage*/): Promise<Layer> {
        return new Promise(resolve => {
            var fk = cp.fork('./client/processes/getClipboardImage.js',[],{cwd: __dirname + '/../../'});
            fk.on('got-string', (err, out) => {
                if (err) {
                    throw err;
                }
                // do some final thigs
            });
        });
    }
}

client/utils/global.js

import { Workspace } from '../../client/utils/Workspace';

export class globals {

    public static activeWorkspaceId: string;
    public static activeWorkspace: Workspace;

}

可能这个cwd: __dirname + '/../../'正在把你带到上面包含 node_modules 的级别。

如果没有有关目录结构的更多信息，很难确定。
