在windows上安装vue/cli时出错

Question

我正试图在windows 10的powershell上使用npm安装vue/cli。安装失败，出现以下错误。

PS C:WINDOWSsystem32> npm install -g @vue/cli

我使用的是节点版本12.18.4

如何解决此问题？

Answer 1

当node作为root安装时，看起来1.22.10版本的yarn在windows上会出现问题。你可以试试1.22.5，看看是否能修复

https://github.com/yarnpkg/yarn/blob/master/CHANGELOG.md#12210-和以前的

Answer 2

此错误似乎出现在1.22.7等新版本的NPM中。

我在这里看到了一些与此bug相关的讨论：https://github.com/yarnpkg/yarn/issues/8358

用sudo前缀更新NPM本身为我(在Ubuntu上(解决了这个问题。奇怪的是，我运行这个程序的环境是一个根帐户。

sudo npm install -g npm

然后，安装带有sudo前缀的yarn修复了我的安装：

sudo npm install -g yarn

我认为这是旧版本的NPM或纱线上的一个错误。通过使用NPM更新自身，您可以获得最新版本的NPM，它可能具有最新版本纱线。
