Angular-cli 错误：找不到模块“@ngtools/json-schema”

Question

我最近在我的项目中运行了 npm update 。完成后，每当我尝试运行 ngserve 时，我都会得到一个

错误：找不到模块“@ngtools/json-schema”

然而，在我的 node_modules 文件中，很明显存在一个 @ngtools 文件。我尝试卸载并重新安装 angular-cli 但仍然收到此错误。

我看到一个可能的错误：

• 确保运行npm update --save，否则不会保存任何更改

如果仍然出现错误，请按照下列步骤操作：

• rm -rf node_modules
• 删除package-lock.json
• npm install
