问题描述

我有一个简单的 nodejs 应用程序，它使用 bcrypt 作为依赖项.在我的本地机器上一切正常，但是当我尝试在 aws ec2 免费层上部署此节点应用程序时，我收到此错误.看起来免费层有一些服务器限制，但 bcrypt 是一个标准库.必须有一种方法可以在 aws 免费层上运行一个简单的节点应用程序

I have a simple nodejs application which uses bcrypt as a dependency. Everything just works fine on my local machine but when I am trying to deploy this node app on aws ec2 free tier I get this error. Looks like there are some server limitations in free tier but bcrypt is a standard library. There has to be a way to run a simple node app on aws free tier

bcrypt@4.0.1 install /home/ubuntu/backend/node_modules/bcrypt
node-pre-gyp install --fallback-to-build

如何在 ec2 免费层上安装 bcrypt?

How can I install bcrypt on ec2 free tier?

推荐答案

我遇到了这个问题，我的问题是使用旧版本的节点 (5.X)，当需要版本 >= 10 时.

I came across this, and my issue was using an older version of node (5.X), when a version >= 10 was required.

所以解决方案可能就像升级 node/npm 一样简单.您可以使用 nvm(节点版本管理器")轻松完成此操作.

So the solution may be as simple as upgrading node/npm. You can easily do this using nvm, the "Node Version Manager"

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

Output

=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

正如上面的输出所说，您应该关闭并重新打开终端或运行命令将 nvm 脚本的路径添加到当前 shell 会话.你可以做任何对你来说更容易的事情.

As the output above says, you should either close and reopen the terminal or run the commands to add the path to nvm script to the current shell session. You can do whatever is easier for you.

安装nvm后，只需运行以下命令即可安装和使用特定版本的node:

After you've installed nvm, you can install and use the specific version of node by simply running this command:

nvm install <version>

例如:

$ nvm install v10.16.3     // Thanks @Joe for your help :)                                              
$ node --version                                                               
v10.16.3

节点升级到版本后>10、可以安装bcrypt

After upgrading node to version > 10, you can install bcrypt

$ npm install bcrypt
