当试图在Chrome控制台中增加从地图中获得的值时,我会得到以下错误(50.0.2661.86):
Uncaught ReferenceError: Invalid left-hand side expression in postfix operation(…)
与Node类似(4.4.3):
ReferenceError: Invalid left-hand side expression in postfix operation

我有一个包含布尔值的vue.js存储,我需要检测组件内部的变化情况。当userEnabled发生变化时,我需要在组件中调用一个方法。我不需要计算新的值。
我的问题是,我应该为此使用'watch',还是有更有效的方法?如果是这样的话,我应该在“挂载”内配置手表吗?
store.js
import Vue from 'vue';
import Vuex from 'vuex';
Vue.use(Vuex);
export const store = new Vuex.Store({
state : {
userEnable
我在后端使用loopback。我得到了这个错误

这是我现在的剧本:
[int]$NumberOfProfiles = Read-Host "Enter the number of profiles You need"
$WhereToWrite = Read-Host "Enter the full path where You'd like to install the profiles"
$Source = Get-Location
$FolderName = "Fish"
$SourceDirectory = "$Source\$Foldername"
