Express 无法安装bcrypt

我在安装bcrypt时遇到此错误。我尝试了以下操作：

aakanksha@aakanksha:~/Documents/shoutbox/node_modules$ sudo npm  install bcrypt

> bcrypt@0.8.1 install     / /home/aakanksha/Documents/shoutbox/node_modules/bcrypt
> node-gyp rebuild

看起来您需要GCC。若我理解正确，shoutbox是您的节点应用程序的名称。按此步骤操作。nom init“然后npm安装bcrypt-save`。这表明nom cmd不存在@narendrasonicc也不工作GCC以什么方式不工作？

npm install -g npm
sudo npm i -g node-gyp && node-gyp clean
But even after running above commands,if i agin install bcrypt it     gives me error.
