Node.js Vue CLI安装问题

我正在学习Vue.JS，需要安装Vue CLI

NodeJS:v13.8.0 Vue CLI:v4.2.2

我安装NodeJS没有问题，但当我转到终端上的文件夹并使用（npm install-g@Vue/CLI）安装Vue CLI时，我遇到了很多错误

MacBook-Pro-de-Cedric:excli cedric$ npm install -g @vue/cli
npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

如果有人知道我如何解决这个问题，那就太好了。

感谢如果您在mac上，请尝试

sudo npm install-g@vue/cli

而不是

npm install-g@vue/cli

进行全局安装。

进行全局安装。

这是从节点路径开始的模块丢失，您可以键入

sudo npm install-g@vue/cli

安装vue，这意味着在全局环境下安装vue，也可以重新设置节点模块路径。

由于节点模块的路径丢失，您可以键入

sudo npm install-g@vue/cli

您必须使用超级用户权限执行

npm install-g

（例如在linux上使用

sudo

），因为您的npm目录似乎在超级用户权限下

这些错误看起来与Vue CLI没有直接关系。它们看起来像是npm设置的问题。你可能需要在谷歌上搜索与npm、macOS相关的答案，就像许多错误都包含在问题中一样……EACCES意味着你需要使用sudo或为用户安装npm，例如google around

如何在macOS上安装nvm

其他部分是gyp eror感谢所有的答案，我发现了问题。我试图在一个目录上创建一个项目。当我在/user/myname上创建它时，它就工作了！这些错误看起来与Vue CLI没有直接关系。它们看起来像是npm设置的问题。你可能需要在谷歌上搜索与npm、macOS相关的答案，就像许多错误都包含在问题中一样……EACCES意味着你需要使用sudo或为用户安装npm，例如google around
