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

我正在将我的节点版本设置为v12.4.0，我确认已设置。但是当我运行npm install-g expo-cli时，它一直使用v9.10.0

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

如何更改npm以使用节点v12.4.0？

Expox-cli在没有正确版本的node的情况下失败。

➜  ~ 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

  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:
