Angular 8：当我尝试 ng 服务时出现 internal/modules/cjs/loader.js 错误

Question

当我克隆我的 Angular 项目并运行“npm install”以在 node_module 中安装所有依赖项时，我遇到了这个错误：

npm ERR! path D:\Project\VipUi\angular\node_modules\.staging\echarts-25586c04\map\js\world.js
npm ERR! code EPERM
npm ERR! errno -4048

我尝试获取队友的 node_module 并将其复制到我的项目中，但我的 powershell 中出现 loader.js 错误

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module 'D:\Project\VipUi\angular\node_modules\@angular\cli\bin\ng'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)

    at startup (internal/bootstrap/node.js:283:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)

我该如何解决这个问题？

Answer 1

npm - EPERM: operation not permitted on Windows

1. 以管理员身份运行 cmd

2. 运行 npm config edit（你会得到记事本 编辑）

3. 将前缀变量更改为 C:\Users\\AppData\Roaming\npm
