NPM: checkPermissions 缺少对 /.../node_modules/is 的写入访问权限。

Question

每次在我的项目上运行npm install时，我都会得到以下错误：

npm WARN checkPermissions Missing write access to /../node_modules/is
npm ERR! path /.../node_modules/is
npm ERR! code ELOOP
npm ERR! errno -62
npm ERR! syscall access
npm ERR! ELOOP: too many symbolic links encountered, access '/.../node_modules/is'

npm ERR! A complete log of this run can be found in:
npm ERR!     /.../.npm/_logs/2017-07-14T15_19_32_340Z-debug.log

在我的 node_modules 文件夹中删除一个名为“is”的快捷方式文件后，问题得到了解决。但在一次成功的 npm install 运行后，它会再次生成。

以下是我的 package.json 文件：

    }
}

我尝试将权限更改为每个人都有读写权限，但没有成功。

Answer 1

如果您正在使用 Mac 或任何基于 Unix 的系统，请尝试以 root/Administrator 权限重新运行该命令。

sudo npm install

Answer 2

这是一个递归依赖项（is 依赖项指向 node_modules/is，这也是 is 依赖项本身将被安装的地方）：

"is": "file:node_modules/is"

如果你想安装is包（这个），请从package.json中删除该行并正确安装：

npm i is --save
