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.一切在我的本地计算机上都可以正常工作，但是当我尝试在AWS EC2免费层上部署此节点应用程序时，出现此错误.看起来免费层有一些服务器限制，但是bcrypt是一个标准库.必须有一种方法可以在AWS Free tier上运行简单的节点应用程序

如何在ec2免费套餐上安装bcrypt?

解决方案

我遇到了这个问题，我的问题是使用的是节点(5.X)的较旧版本，而版本号为> = 10.

因此，解决方案可能像升级node/npm一样简单.您可以使用节点版本管理器" nvm 轻松完成此操作;

NVM安装

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

如上面的输出所示，您应该关闭然后重新打开终端，或者运行命令以将nvm脚本的路径添加到当前的shell会话中.您可以做对自己更轻松的事情.

安装nvm后，只需运行以下命令即可安装和使用特定版本的节点:

nvm install node <version>

例如:

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

将节点升级到版本>后， 10，您可以安装bcrypt

$ npm install bcrypt

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

How can I install bcrypt on ec2 free tier?

解决方案

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

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

NVM Installation

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

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.

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

nvm install node <version>

For example:

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

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

$ npm install bcrypt
