同学你好，看报错可能是权限的问题，建议用下面的命令试试

sudo npm install -g cnpm --registry=https://registry.npm.taobao.org

祝学习愉快！

同学你好，问题解答如下：

1、这个提示就是先卸载之前的旧版本，然后再安装新版本，可以使用这两步命令来操作

2、cnpm是淘宝镜像的命令，如果没有安装过就不能使用，用npm安装就可以。

或者先安装一下镜像

npm i -g cnpm --registry=https://registry.npm.taobao.org

然后再用cnpm会快一些。

祝学习愉快！

同学你好，从上传的内容中可以看到删除报错了，可能是网络的问题。

建议使用cnpm uninstall vue-cli -g 命令删除，然后重启电脑再看看。如果还是有问题的话，建议直接升级 npm install -g @vue/cli ，一般会进行覆盖的。

好像还是不太行
尝试直接用vue create travel 来干，提示如下
```
wanglimindeMacBook-Air:Desktop wanglimin$ vue create travel

  vue create is a Vue CLI 3 only command and you are using Vue CLI 2.9.6.
  You may want to run the following to upgrade to Vue CLI 3:

  npm uninstall -g vue-cli
  npm install -g @vue/cli
```
之前用cnpm uninstall vue-cli -g 是提示
-bash: cnpm: command not found

是不是还需要安装下 cnpm这个工具先？怎么安装呢？
