Question

我在nettutsplus上关注了一个教程,在运行npm update -g npm之后,当我键入npm时,我的npm不再存在.这是错误.出了什么问题,我该如何解决？

我如何更新npm？

npm update npm -g

npm update npm -g您还可以通过执行npm update而不使用任何参数来更新所有过时的本地软件包,或者通过执行npm update -g来更新全局软件包.

有时,npm的版本会进展,以至于无法使用已安装的版本正确安装当前版本.(考虑一下,如果更新命令中有错误.)

在这些情况下,您可以这样做:

curl https://npmjs.org/install.sh | SH

更新

安装脚本位置已被移动,因此请尝试:

curl -L https://npmjs.org/install.sh | SH
