node.js - OpenShift : ImportError: No module named gyp: on NodeJs/Mongo cartridge

Question

我有一个安装了 NodeJS 和 MongoDB 盒的 OpenShift 设备。我添加了 KeystoneJS ，当我尝试推送更新的代码时，由于缺少 gyp 模块，构建失败。下面是完整的错误堆栈。

还有其他人遇到过 Node/mongo 盒丢失 gyp 模块的情况吗？

谢谢! 尼拉夫

Answer 1

这个错误也突然开始发生在我身上，尽管它以前曾经有效过。由于某种原因，Python gyp 模块在卡带中不可用或无法找到。虽然我不知道发生了什么变化，但我通过升级用于部署的 npm 安装找到了解决方法。

为此，我添加了两个 Action Hook :

1. .openshift/action_hooks/pre_build

   #!/bin/sh
   
   #  We need to move the package.json file out of the way in pre_build, so
   #  that the OpenShift git post-receive hook doesn't try and use the old
   #  npm version to install the dependencies.
   mv ${OPENSHIFT_REPO_DIR}/package.json \
      ${OPENSHIFT_TMP_DIR}/${OPENSHIFT_APP_UUID}_package.json
   

2. .openshift/action_hooks/build

   #!/bin/sh
   
   #  we moved the package.json file out of the way in pre_build,
   #  so that the OpenShift git post-receive hook doesn't try and use the
   #  old npm version to install the dependencies. Move it back in.
   mv ${OPENSHIFT_TMP_DIR}/${OPENSHIFT_APP_UUID}_package.json \
      ${OPENSHIFT_REPO_DIR}/package.json
   
   cd ${OPENSHIFT_REPO_DIR}
   
   # We need an updated npm available for node-gyp to work reliable
   npm install npm
   
   # Now install the packages with the new npm version
   ./node_modules/.bin/npm install
   

以这种方式使用替代 npm 安装的想法取自 https://github.com/ryanj/nodejs-custom-version-openshift/tree/master/.openshift/action_hooks

我还尝试使用环境变量并设置$PYTHONPATH，但在构建过程中该方法没有成功(尽管我让它在手动安装上工作)。
