无法使用Brew开关更改节点的版本 [英] Unable to change version of node with brew switch

问题描述

我正在尝试使用节点8.9.1，但是当尝试使用brew更新时，它说已经安装了8.9.1

I'm trying to use node 8.9.1 but when trying to update using brew it says 8.9.1 is already installed

James-MacBook:~ james$ brew upgrade node
Error: node 8.9.1 already installed

但是当检查版本时会显示

But when checking the version it shows

James-MacBook:~ james$ node --version
    v0.10.48

所以我试图切换到8.9.1

So then I tried to switch to 8.9.1

James-MacBook:~ james$ brew switch node 8.9.1
Cleaning /usr/local/Cellar/node/8.9.1
7 links created for /usr/local/Cellar/node/8.9.1

但它仍显示为0.10.48

But it is still showing as 0.10.48

James-MacBook:~ james$ node --version
v0.10.48

推荐答案

听起来您已安装了某些版本的节点，而未使用Homebrew.

It sounds like you have some version of node that is installed without using Homebrew.

1. 首先，通过检查主目录ls -la中是否有.nvm目录来检查是否已使用nvm安装了节点.

1. First of all, check if you installed your node with nvm by check if you have a .nvm directory in home directory ls -la

1. 如果这样做，请删除该目录
2. brew update && brew install node@8(所需的任何节点)
3. brew unlink node@0
4. brew link --force node@8
5. 进行酿造更新&& brew升级节点@ 8

1. if you do, remove that directory
2. brew update && brew install node@8 (whichever node you want)
3. brew unlink node@0
4. brew link --force node@8
5. Do brew update && brew upgrade node@8
