这个错误是什么意思，为什么有时会发生？

我在一个django项目中使用vuejs。

当我在vuejs终端做：npx webpack --config webpack.config.js我得到这样的东西：
[webpack-cli]错误：
Vue包版本不匹配：

  • vue@3.3.4（../vue-chat-app-two/node_modules/vue/index.js）
  • vue-template-compiler@2.7.14（.../vue-chat-app-two/node_modules/vue-template-compiler/package.json）

这可能会导致工作不正常。确保两者使用相同的版本。如果你使用的是vue-loader@>= 10.0，只需更新vue-template-compiler。如果你使用的是vue-loader@<10.0或vueify，重新安装vue-loader/vueify应该会将vue-template-compiler升级到最新版本。

我试着**@Ewan Reveille的**回答：
我将vue-template-compiler改为3.3.4而不是2.7.14，然后我做了npm install。
我在航站楼里看到了这样的东西：

webpack.config.js：

const path = require('path');
const { VueLoaderPlugin } = require('vue-loader');
const BundleTracker = require('webpack-bundle-tracker');

module.exports = {

  output: {

该错误可能来自Vue.js版本与其模板编译器版本之间的不兼容。要更正此错误，您应该修改以下行：“vue-template-compiler”：“^2.7.14”，在“devDependencies”中的“vue-template-compiler”行：“^3.3.4”，.
然后，在终端中启动命令“npm install”来更新依赖项。
我希望这有帮助！
