解决方案一： 在项目根目录下安装vue-template-compiler模块：npm install vue-template-compiler --save-dev
[root@iZbp1ge4ctw809v4lhhrnaZ ~]# npm install vue-template-compiler --save-dev

解决方案二： 清除缓存并重新安装依赖
npm cache clean --force
然后，删除项目根目录下的node_modules文件夹，重新安装项目的依赖：
npm install
解决方案三： Vue版本不匹配导致，可以查看package.json版本管理中的vue-template-compiler版本
"dependencies": {
"vue-template-compiler": "^2.7.7",
}
然后通过 npm list vue 查看已安装的Vue版本。
PS E:\myblog\blog> npm list vue
myblog@1.0.0 E:\myblog\blog
`-- @vssue/vuepress-plugin-vssue@1.4.8
`-- vssue@1.4.8
`-- vue@2.7.8
确保项目中安装的Vue版本和"vue-template-compiler": "^2.7.7"兼容。如果不兼容，尝试升级或降级Vue版本，或更新vue-template-compiler模块的版本。
解决方案四： 如果你的项目使用了webpack作为构建工具，那么可能是webpack配置的问题导致的错误，检查webpack配置，通常是webpack.config.js或vue.config.js，确保vue-loader的版本与vue-template-compiler模块的版本兼容。如果以上方法都没有解决问题，那么可能是其它依赖模块的问题导致的错误，检查项目中的其他依赖模块是否与vue-template-compiler模块的版本兼容
