npm install 不工作，从 git 克隆我的项目后无法安装任何节点模块

Question

我从 git 克隆了我的项目，但在尝试执行 npm install 时，它不起作用。

我无法修复任何错误 - 例如，当尝试使用 npm install --save core-js@^3 修复 core-js 错误时，我仍然收到相同的消息，我需要升级。

为什么会这样？在我克隆这个 repo 之前没有错误？

Answer 1

即使我也遇到过同样的问题...这可能对您有帮助.. :)

我创建了一个名为“projects (Folder Name)”的文件夹，其中我已经克隆了我的项目 - 名为“xyz project (projects >> xyz project)”..

现在我错误地尝试安装 - npm install in "projects folder (parent folder)"..

但节点模块必须安装在“xyz 项目”（子文件夹）中

所以当我在 xyz 项目中使用 npm i... 时，节点模块已成功安装..

试试这个..

Answer 2

试试：

npm cache clean --force
npm install
