Question

我正在尝试安装自耕农。但我遇到了以下错误。

C:\Users\xxxxx>npm install -g yo
npm WARN deprecated npmconf@2.1.2: this package has been reintegrated into npm a
nd is now out of date with respect to npm
C:\Users\xxxxx\AppData\Roaming\npm\yo -> C:\Users\xxxxx\AppData\Roaming\npm\
node_modules\yo\lib\cli.js

> yo@1.7.0 postinstall C:\Users\xxxxx\AppData\Roaming\npm\node_modules\yo
> yodoctor

operable program or batch file.

然后我尝试'npm install -g yeoman-doctor'来绕过这个错误。安装了自耕农医生后，就可以找到如下的医生。

C:\Users\xxxx>yodoctor

但不幸的是，当我重新尝试'npm install -g yo'时，问题仍然存在。

你能告诉我解决方法吗？谢谢。

Answer 1

错误显示您的npm已过时。您需要的是先更新npm。

尝试 npm -g update

或

npm -g install npm

Answer 2

我遇到的问题是由我的 .npmrc 文件中的错误前缀值引起的，该值指向不存在的 Node.js 版本。它完全破坏了我全局安装 npm 包的能力。从我的 .npmrc 文件中删除前缀解决了这个问题。这可能是 Yeomen Doctor 可以学会检测的东西。

要在 .npmrc 中设置前缀值，您必须使用以下命令

set npm_config_prefix=""

'npm install -g yo'时失败了吗？
