当前回答

如果在授予权限后仍然不工作,请尝试运行这些命令:

mkdir ~/.npm-global

npm config set prefix '~/.npm-global'

export PATH=~/.npm-global/bin:$PATH

source ~/.profile

最后用这个命令进行测试

NPM install -g jshint

这对Windows不起作用。

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

尝试在您尝试的任何命令之前添加sudo。

像这样:sudo NPM install

在Linux/UNIX中,将sudo与命令一起使用通常会将权限提升到超级用户级别。在Windows系统中,超级用户帐户通常被称为“Administrator”。在Linux/Unix中,超级用户帐户通常命名为“root”。

root用户拥有访问、修改或删除计算机上几乎所有文件的权限。普通用户帐户可以访问、修改或删除的文件要少得多。对普通帐户的限制可保护您的计算机免受未经授权或有害程序或用户的侵害。有些进程要求您对通常没有访问权限的文件或文件夹执行操作。安装一个每个人都可以访问的程序就是这些操作之一。

在本例中,使用sudo运行安装命令可以为您提供超级用户的权限,并允许您修改普通用户没有权限修改的文件。

安装React需要超级用户级别的权限。在Linux/Unix中,超级用户帐户通常命名为“root”。

要获得超级用户权限,只需在您的终端上运行以下命令:

sudo -i

然后运行命令安装React:

npm install -g create-react-app

但是,reactjs团队鼓励我们使用以下命令,而不是安装全局包。

npx create-react-app app_name

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

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。
