问题描述

我是Stackoverflow的新手，所以大家好！

I'm new to Stackoverflow, so "hi" to everyone!

在OpenShift Online(免费的入门帐户)上进行部署也是我的新手.部署需要NPM打包的夏普( https://www的个人NodeJS应用时，我遇到以下错误. npmjs.com/package/sharp ).

I'm also new to deployment on OpenShift Online (free starter account). I run into the following error when deploying a personal NodeJS app requiring NPM-package sharp (https://www.npmjs.com/package/sharp).

该应用是二进制版本"( https:直接从本地Git存储区////docs.openshift.com/container-platform/3.6/dev_guide/dev_tutorials/binary_builds.html ).开始构建时，我得到以下输出(相关的初始行):

The app is a "binary build" (https://docs.openshift.com/container-platform/3.6/dev_guide/dev_tutorials/binary_builds.html) directly from a local Git repo. When starting the build, I get the following output (initial, relevant lines):

Receiving source from STDIN as archive ...

构建完成并自动触发新的部署，但是启动失败，当然:

The build finishes and auto-triggers a new deployment, which fails starting, of course:

我在Electron( https://github.com的上下文中找到了关于此错误的一些讨论. com/lovell/sharp/issues/892 )或同时使用节点画布(我不这样做； https://github.com/lovell/sharp/issues/843 ).由于我也不熟悉Dockers等，因此很难提取与我的案例相关的信息.

I found several discussions on this error in the context of Electron (https://github.com/lovell/sharp/issues/892) or when node-canvas is also used (which I don't; https://github.com/lovell/sharp/issues/843). It's hard for me to extract the information relevant for my case, since I'm also not familiar with Dockers etc.

在我的本地计算机上(Ubuntu 16.04)可以很好地安装该锋利的软件包，因此该应用程序可以正常运行.我还尝试在主app.js文件中明确要求Sharp作为第一行，这没有帮助.

The sharp package installed fine on my local machine (Ubuntu 16.04), and consequently, the app runs fine. I also tried explicitly requiring sharp as very first line in my main app.js file, which did not help.

感谢所有帮助，谢谢！

编辑7月2日:在上述与电子有关的讨论中，我想到了设置环境变量的想法

Edit July 2: From the above-mentioned Electron-related discussion, I took the idea to set the env-variable

LD_PRELOAD="/opt/app-root/src/node_modules/sharp/vendor/lib/libz.so"

在OpenShift上的NodeJS-app的构建环境中.构建日志更改如下:

in the build-environment for the NodeJS-app on OpenShift. The build log changed as follows:

Receiving source from STDIN as archive ...

构建过程中的警告已消失，但该应用程序仍然无法启动，并且错误与之前完全相同. (是的，在主app.js中，我确实首先加载了Sharp.)

The warning during the build is gone, but the app still does not startup with exactly the same error than before. (And yes, I do load sharp as first thing in the main app.js.)

我不能以某种方式直接告诉NodeJS(在主app.js中)为某些路径(或库)提供优先级吗?

Can't I somehow directly tell NodeJS (in the main app.js) to give preference to some path (or library)?

推荐答案

现在，我已经解决了该问题.将LD_PRELOAD变量添加到内部版本和部署环境并没有帮助.但是，一旦我修改了npm start脚本以在启动应用程序之前添加变量，它就会起作用:

By now I solved the problem. Adding the LD_PRELOAD variable to the build and the deployment environments did not help. However, it worked once I modified the npm start script to add the variable before starting the app:

"start": "LD_PRELOAD='/opt/app-root/src/node_modules/sharp/vendor/lib/libz.so' node app.js"

在我的主要app.js文件中，我仍然首先需要Sharp.没有测试这是否真的必要.

I am still requiring sharp as first thing in my main app.js file; did not test whether this is actually necessary.
