"getActivePinia()" was called but there was no active Pinia. Did you forget to install pinia

这个错误通常在使用 Pinia 库时出现，它是一个状态管理库，类似于 Vuex。这个错误的原因是你在调用 `getActivePinia()` 函数时没有安装或初始化 Pinia。

要解决这个问题，你需要确保在使用 Pinia 之前正确安装了它。你可以通过以下步骤来安装和初始化 Pinia：

1. 首先，确保你已经安装了 Pinia。可以使用 npm 或 yarn 进行安装：

npm install pinia

或者

yarn add pinia

2. 在你的应用程序的入口文件（例如 main.js）中导入 Pinia 并初始化它：

import { createApp } from 'vue'
import { createPinia } from 'pinia'

const app = createApp(App)
const pinia = createPinia()
app.use(pinia)

app.mount('#app')

3. 确保你在使用 `getActivePinia()` 函数之前已经正确设置了 Pinia 的安装。

通过以上步骤，你就可以正确安装和初始化 Pinia，并且不再会遇到 "getActivePinia() was called but there was no active Pinia" 的错误了。

getActivePinia()" was called but there was no active Pinia. Did you forget to install pinia

在你提供的代码中，错误是由于在没有激活Pinia的情况下调用了getActivePinia。这通常是因为你在使用Pinia之前没有正确注册它。

要解决这个问题，你需要确保在使用Pinia之前先正确注册它。在你的main.js文件中，确保在创建应用程序之前使用createPinia创建Pinia实例，并将其挂载到应用程序上。例如：

import { createApp } from 'vue';
import { createPinia } from 'pinia';
import App from './App.vue';
import router from './router';

const pinia = createPinia();
const app = createApp(App);

app.use(pinia).use(router).mount('#app');

然后，在你的其他文件中，如permission.ts或user.js，你可以通过引入pinia来使用Pinia实例。例如：

import pinia from '@/stores/index';
import { useUserStore } from '@/stores/user';

const userStore = useUserStore(pinia);

通过这样的设置，你就可以在其他文件中正确使用Pinia实例，并避免出现"getActivePinia()" was called but there was no active Pinia. Did you forget to install pinia"的错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

getActivePinia()" was called but there was no active Pinia. Did you forget to install pinia?

This error typically occurs when you try to call `getActivePinia()` without having Pinia installed or without having an active Pinia instance. To fix this issue, you need to make sure that Pinia is properly installed and initialized in your project.

Here are a few steps you can follow to resolve this error:

1. Install Pinia: Run the following command in your terminal or command prompt to install Pinia using npm or yarn:

   npm install pinia

or

   yarn add pinia

2. Initialize Pinia: In your main entry file (e.g., `main.js` or `main.ts`), import and initialize Pinia by creating a new instance:

   import { createPinia } from 'pinia';

   const pinia = createPinia();

3. Use the Pinia instance: Make sure to use the `pinia` instance you created to access the Pinia functionalities throughout your application.

By following these steps, you should be able to resolve the error and have an active Pinia instance for your application.
