node.js - NVM:npm install -g 始终使用错误版本的 Node

Question

我正在尝试安装一个名为 expo-cli 的软件包，但它失败了，因为 npm 一直使用错误版本的 Node 。

我将 Node 版本设置为 v12.4.0，我确认已设置。但是当我运行 npm install -g expo-cli 时，它继续使用 v9.10.0

➜  ~ nvm current
v12.4.0
➜  ~ node -v
v12.4.0
➜  ~ npm install -g expo-cli

如何更改 npm 以使用 Node v12.4.0？

如果没有正确版本的 Node ，Expo-cli 会失败。

➜  ~ expo init my-app
zsh: command not found: expo
➜  ~ nvm list
         v8.0.0
        v9.10.0
        v10.8.0
->      v12.4.0
default -> v12.4.0
node -> stable (-> v12.4.0) (default)
stable -> 12.4 (-> v12.4.0) (default)
iojs -> N/A (default)
lts/* -> lts/dubnium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.16.0 (-> N/A)
lts/dubnium -> v10.16.0 (-> N/A)
➜  ~ nvm use v9.10.0
Now using node v9.10.0 (npm v6.9.0)
➜  ~ expo init my-app
/Users/edmundmai/.nvm/versions/node/v9.10.0/lib/node_modules/expo-cli/bin/expo.js:12
  throw new Error('expo-cli supports Node versions 8.x.x, 10.x.x and newer.');
  ^

更新:

This is what happens when I try to scope the node version:

检查 ~/.npmrc 中是否有指向 v9.10.0 模块安装路径的前缀设置。这将导致在使用其他版本的 Node 时 npm 将全局包安装在错误的位置。
