Macos 角度安装问题和权限在Mac上失败为什么？

这是第一次使用角度。我检查是否有所需的节点版本，但我将获得权限错误，我不确定为什么？我正在使用mac，并且我遇到了权限失败或拒绝错误。我还尝试了sudo npm安装-g@angular/cli。猜猜看？因为我不知道该怎么办

stephaniegalindo@Stephanies-MacBook-Pro ~ % npm install -g @angular/cli

您的

~/.npm global

目录中似乎存在权限问题

如果存在.npm global文件夹，请首先检查主目录

如果有，试试这些命令

sudo chown -R $(whoami) ~/.npm
sudo chown -R $(whoami) ~/.npm-global

然后再次尝试安装Angular

如果您没有.npm global文件夹，我建议您使用节点版本管理器重新安装npm

stephaniegalindo@Stephanies-MacBookPro~%SudoChown-R$（whoami）~/.npm密码：stephaniegalindo@Stephanies-MacBook Pro~%sudo npm安装-g@angular/cli/Users/stephaniegalindo/.npm global/bin/ng->/Users/stephaniegalindo/.npm global/lib/node_modules/@angular/cli/bin/ng>@angular/cli@8.3.20postinstall/Users/stephaniegalindo/.npm global/lib/node_modules/@angular/cli>node./bin/postinstall/script.js+@angular/cli@8.3.20在103.863s中更新了2个软件包这是添加的，但是说ng不是一条命令，似乎您没有设置ng的路径。检查是否在

~/.nvm/versions/node/$（node--version）/bin

下安装了ng。如果你有ng。尝试将此行添加到~/.bashrc文件中

export PATH=~/.nvm/versions/node/$（node--version）/bin:$PATH

然后运行

source~/.bashrc

。然后再次尝试安装angular。
