当前回答

如果你正在运行Linux(如:Arch)

# npm -g install packageName

默认情况下,该命令将包安装在/usr/lib/node_modules/npm下,并且需要root权限才能这样做。

允许用户范围的安装

要允许为当前用户安装全局包,请设置npm_config_prefix环境变量。npm和yarn都使用这个。

mkdir ~/.node_modules
cat ~/.profile
PATH="$HOME/.node_modules/bin:$PATH"
export npm_config_prefix=~/.node_modules

重新登录或更新源代码以更新更改。

你也可以为npm install指定——prefix参数。但是,不建议这样做,因为每次安装全局包时都需要添加它。

$ npm -g install packageName --prefix ~/.node_modules

所以你不需要chown文件夹权限

其他回答

使用sudo用户安装npm:

sudo npm install -g create-react-app 

而不是 NPM install -g create-react-a pp。

对于linux / ubuntu如果命令

NPM install -g <package_name>

修复:安装与根权限

Sudo NPM install <package_name> -g

类似于POsha的答案,但这是我在ubuntu 19上工作的方法

sudo npm i -g ngrok --unsafe-perm=true --allow-root

从这个链接

经过长期的研究,我明白了在mac OS中安装angular cli不需要什么,只需使用sudo npm install -g @angular/cli,你的终端会提示密码,输入你的密码,然后继续安装cli。这对我很管用。

在CentOS 8流中遇到

解决方案

(1/4)创建node_modules文件夹

$ sudo mkdir /usr/local/lib/node_modules

(2/4)与当前用户共同拥有

$ sudo chown -R $USER /usr/local/lib/node_modules/

(3/4)拥有bin文件夹

$ sudo chown -R $USER /usr/local/bin/

(4/4)拥有共享文件夹

$ sudo chown -R $USER /usr/local/share/
