node.js npm

我尝试从节点项目中的控制台运行“npm outdated”。但我收到此错误：

npm ERR! Cannot read property 'length' of undefined

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\User\AppData\Roaming\npm-cache\_logs\2019-03-31T12_26_30_745Z-debug.log

这是日志中的错误：

当我尝试全局运行它时也会发生这种情况。有人遇到过这种情况吗？

Answer 1

似乎在下一个版本中得到修复，但尚未发布。

https://github.com/npm/cli/pull/173

您可以安装预发布版本来修复它。

npm -g i npm@next

更新

NPM 6.9.2 已经发布

npm install -g npm

Answer 2

npm 中有一个错误，但您可以轻松修复它：

转到您的 npm 文件夹（即 /usr/local/lib/node_modules ）并找到一个 outdated.js 文件（即 Mac 的 /usr/local/lib/node_modules/npm/lib/outdated.js 或 Windows 的 C:\Users\YOUR_USER_NAME\AppData\Roaming\npm\node_modules\npm\lib\outdated.js ）
找到一个函数 makePretty 并将
```
deppath
```
更改为
```
deppath || 'global'
```

就我而言，它是第 152 行

希望它有所帮助！ 🙂

Answer 3

您也可以尝试 npm upgrade -g 。对我来说很有效。
