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

当在ubuntu中安装全局包时，你需要特殊的写入权限，因为你正在写入usr/bin文件夹。这是出于安全考虑。 所以，每次你安装一个全局包时，使用:

sudo npm install -g [package-name]

对于您的具体情况，它将是:

sudo npm install -g typescript

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。

您可以简单地更改所有者，或者在执行这样的命令之前使用sudo

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules(更改owner)

or

sudo npm install -g json-server

就是这样。

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

你所需要做的就是将USER添加到/local/lib的所有者

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

编辑:

要精确地定位并只定位node_modules文件夹，请在使用前一个命令之前尝试使用这个命令:

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