发生未经处理的异常：请求的模块'@angular/compiler'未提供名为 'ClassStmt' 的导出

Question

我只是随机开始得到这个错误：

发生未处理的异常：请求的模块"@angular/compiler"不提供名为"ClassStmt"的导出

node.js版本：14.17.0

package.json>相关性：

"dependencies": {
"@angular/animations": "~13.2.2",
"@angular/cdk": "^13.0.3",
"@angular/common": "~13.2.2",
"@angular/compiler": "~13.2.2",
"@angular/core": "~13.2.2",
"@angular/elements": "^13.2.2",
"@angular/forms": "^13.2.2",
"@angular/material": "13.0.3",
"@angular/platform-browser": "~13.2.2",

},

"@typescript-eslint/parser": "5.3.0",
"eslint": "^8.3.0",

}

这个问题只是随机发生的。在上一个PR中，我没有看到package-lock.json上有任何git-diff更改。我认为这与角度依赖关系之间的依赖关系版本差异有关。太随意了！

Answer 1

好吧，我想明白了。

@angular/compiler、@angular/cli和@angular/compiler-cli依赖项都需要在版本上匹配。

在我同步了那些依赖版本之后，错误就消失了。

Answer 2

我以前遇到过类似的问题。要解决此问题，您可以尝试以下步骤：

删除node_modules目录。删除package-lock.json文件。运行npm install以重新安装依赖项。最后，执行ng-server来启动应用程序。
