Question

我试图将带有codeship的nodejs后端部署到弹性beanstalk。但每次我收到以下错误：

bcrypt@1.0.3 install /tmp/deployment/application/node_modules/bcrypt
node-pre-gyp install --fallback-to-build

module.js:471
throw err;
^

有谁知道如何修复它？一直试图修复它几天，非常感谢帮助！

Answer 1

请尝试使用bcrypt.js模块，而不要使用bcrypt模块，后者是一个更新/最新的npm模块。

运行npm install bcryptjs 然后npm install

Answer 2

查看此GitHub评论：https://github.com/kelektiv/node.bcrypt.js/issues/509#issuecomment-313693838

TL; DR：作为一种变通办法，在运行npm install bcrypt之前运行npm install

Answer 3

首先确保您没有上载节点模块文件夹，并且npm install命令在实例上可用。

此问题与node-pre-gyp有关。 bcrypt的依赖项。

对于AWS Elastic Beanstalk，当部署到运行Node 8.x的Elastic Beanstalk时，node-gyp没有足够的权限来写入tmp目录。 bcrypt无法安装，并且应用程序部署将失败。

一种解决方法是将.npmrc文件添加到项目的根目录，这将强制node-gyp以root身份运行并允许安装完成。 .npmrc的文件内容：

# Force npm to run node-gyp also as root, preventing permission denied errors in AWS with npm@5 or @6
unsafe-perm=true

另一种替代方法（也许是更正确的方法）是使用以下代码制作.ebextensions文件：

.ebextensions：00_change_npm_permissions.config：

  "/opt/elasticbeanstalk/hooks/appdeploy/post/00_set_tmp_permissions.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      chown -R nodejs:nodejs /tmp/.npm

这将为您提供足够的权限来运行node-gyp

Answer 4

我创建了一个public class XmlBasedDAO { private XMLJdbcConnection XMLJdbcConnection; public XmlBasedDAO(XMLJdbcConnection XMLJdbcConnection) { this.XMLJdbcConnection = XMLJdbcConnection; } public XMLJdbcConnection getXMLJdbcConnection() { return XMLJdbcConnection; } }文件，

.npmrc

这似乎已经做到了。

Answer 5

在您的bcryptjs中添加package.json依赖项，然后npm install应该可以处理所有依赖项。
