我使用以下命令在ubuntu 18.04中安装web3.js：
sudo npm install -g web3
并得到以下错误：

虽然“sudo npm install -g [email protected]”工作正常，但我想要更新web3.js.请帮忙！
希望这可以帮助
sudo npm install --save web3 --unsafe-perm = true --allow-root
@Kashish Khullar，您的解决方案适用于大多数软件包，但在我尝试安装drizzle时无效。现在我找到了这个的根本原因。我在我的Ubuntu 18.04中安装了带有binary的Nodejs，它显示了许多NPM软件包如Web3.js的上述错误。所以我从我的系统中完全卸载了Nodejs和npm，并再次使用apt-get包管理器安装它，即sudo apt install nodejs npm。现在一切正常，没有任何问题。
