我想要的只是在我的节点中安装 web3。

我的节点版本是v8.9.4 web3版本是1.0.0-beta.46

但我不明白的是，这个骗子一直在失败。我只是运行节点，我看到一个可怕的消息，我没有加密模块。。。

通常我只是安装我的模块而不是 -g 选项，而是 --保存一个。但是我无法解决我的问题，所以我只是使用 -g 选项安装 scrypt

# npm install -g scrypt

但是错误消息我不明白为什么会发生在我身上？

# npm install -g scrypt

> scrypt@6.0.3 preinstall /opt/nodejs/lib/node_modules/scrypt
> node node-scrypt-preinstall.js

我尝试将web3重新安装到我的模块中，消息将会显示。我觉得node gyp是这个问题的关键，所以能不能请教一下为什么会出现这个问题？
