由于重复 "Please run npm install -g @vue/cli-upgrade and try again."，无法升级 vue cli

Question

我尝试升级 vue cli， 并注意到我需要安装 @vue/cli-upgrade.

ueda@klingsor:~/ml$ sudo vue upgrade

  Command vue upgrade requires a global addon to be installed.
  Please run npm install -g @vue/cli-upgrade and try again.

所以，我已经安装了 @vue/cli-upgrade 并再次尝试 vue 升级，但是消息重复出现。

ueda@klingsor:~/ml$ sudo npm install -g @vue/cli-upgrade
+ @vue/cli-upgrade@3.12.1
updated 1 package in 7.273s
ueda@klingsor:~/ml$ sudo vue upgrade

  Command vue upgrade requires a global addon to be installed.
  Please run npm install -g @vue/cli-upgrade and try again.

另外，vue cli的版本还是3.4.1

ueda@klingsor:~/ml$ vue --version
3.4.1

如何将我的 vue-cli 升级到 4？感谢您的建议！

我的环境是ubunto 14.04，npm是6.13.7版本

ueda@klingsor:~/ml$ cat /etc/os-release 
NAME="Ubuntu"
VERSION="14.04.2 LTS, Trusty Tahr"

ueda@klingsor:~/ml$ npm --version
6.13.7```

我通过运行修复了它：

sudo npm install -g @vue/cli

由于重复 "Please run npm install -g @vue/cli-upgrade and try again."，无法升级 vue cli

Can't upgrade vue cli due to repeating "Please run npm install -g @vue/cli-upgrade and try again."

vue.js

vue-cli
