对于linux / ubuntu如果命令
NPM install -g <package_name>
npm WARN deprecated superagent@4.1.0: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header). This notice will go away with v5.0.2+ once it is released.

修复:安装与根权限
Sudo NPM install <package_name> -g
我可以通过安装nvm来解决这个问题，然后将node设置为最新版本。
使用curl安装nvm(最新版本请到nvm.sh)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
列出可用节点版本
nvm ls
v10.12.0
默认值-> v10.12 (-> v10.12.0)
节点->稳定(-> v10.12.0)(默认)
稳定-> 10.12 (> v10.12.0)
.．.
选择要使用的节点版本
nvm use v10.12
NVM不兼容NPM配置“前缀”选项:当前设置为“”
运行此命令取消设置该选项:
nvm use --delete-prefix v10.12.0
按照上面的命令，你就可以在Ubuntu中安装react/angular了。
为了尽量减少权限错误的机会，你可以配置npm使用不同的目录。在本例中，您将在主目录中创建并使用一个隐藏目录。
备份你的电脑。
在命令行中，在你的主目录中，创建一个用于全局安装的目录:
mkdir ~/.npm-global
配置npm使用新的目录路径:
npm config set prefix '~/.npm-global'
在您首选的文本编辑器中，打开或创建~/。配置文件，并添加这一行:
export PATH=~/.npm-global/bin:$PATH
在命令行，更新你的系统变量:
source ~/.profile
要测试新配置，请在不使用sudo的情况下全局安装一个包。
