Bcrypt Elastic beanstalk nodejs 部署

Question

我正在尝试将我的 nodejs 后端与 codeship 部署到弹性 beantalk。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;
^

有谁知道如何修理它？已经尝试修复它几天了，非常感谢帮助！

Answer 1

尝试使用bcrypt.jsmodule 而不是bcrypt更新/最新的 npm 模块。

运行npm install bcryptjs 然后npm install

Answer 2

首先确保您没有上传节点模块文件夹，并且 npm install 命令正在实例上运行。

这个问题与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 没有足够的权限写入 tmp 目录。bcrypt 将不会安装，并且应用程序部署将失败。

解决方法是将 .npmrc 文件添加到项目的根目录，该文件将强制 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

另一种选择（也许更正确的方法）是使用代码制作 .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访问权限来运行 node-gyp
