选择节点版本时权限被拒绝的部署问题答案

【问题标题】：deployment problem with permission denied while selecting node version选择节点版本时权限被拒绝的部署问题
【发布时间】：2020-12-21 23:11:00
【问题描述】：

从一开始，我就一直在为我的 node 12 Web 应用程序使用 kudu 部署时遇到问题。这次我在管道日志中有select node version failed，但是当我从链接访问日志详细信息时是Not setting execute permissions for bash。最糟糕的是代码或管道中没有任何变化，有一天你醒来，你的应用程序不再工作了。这是第三次发生，每次在可用版本列表中都有可用的新版本节点时。有人可以指出可以使用超过一个月的解决方案吗？我使用了 kudu 文档中节点 Web 应用程序的默认脚本，只是将 npm 替换为 yarn。并在应用配置中使用环境变量WEBSITE_NODE_DEFAULT_VERSION 和WEBSITE_NPM_DEFAULT_VERSION。我尝试了带有或不带有 npm 的节点版本 var 的每种组合，......没有任何效果。我真的需要一个长期的解决方案来最终解决这个问题，否则我想我会转向更稳定的替代方案。任何帮助深表感谢。一个可以相关的问题https://github.com/projectkudu/kudu/issues/2870#issuecomment-443464291

这是我的 .deployment 文件

[config]
command = bash ./scripts/bash/deploy.sh

这是我在scripts/bash/deploy.sh 中的shell 文件，您可以看到与使用命令kuduscript -y --node 检索的默认自定义部署脚本的唯一区别是yarn 而不是npm

我只将变量WEBSITE_NODE_DEFAULT_VERSION 设置为12.18.2（这一次，但我已经尝试了多种组合），而我没有设置WEBSITE_NPM_DEFAULT_VERSION 变量。这是我尝试使用 git local 方法部署时的输出，使用命令git push azure master:master:

我们无法重现您描述的现象。你可以告诉我们你做了什么以及如何重现问题。详细告诉我们这些步骤，以便您更好地解决问题。或者直接提出支持票寻求帮助，微软工程师会帮你查日志。
@JasonPan 我编辑了帖子并放置了所有细节。提前谢谢你
另外，从 kudu 调试 bash 控制台，当我输入 node -v 时，我得到 v14.15.0。这是基于 linux 的容器的唯一版本吗？
尝试在新创建的插槽上部署时出现同样的错误

标签： azure-web-app-service kudu

【解决方案1】：

在评论SELECT_NODE_VERSION 命令后解决（暂时）

# SELECT_NODE_VERSION="$KUDU_SELECT_NODE_VERSION_CMD \"$DEPLOYMENT_SOURCE\" \"$DEPLOYMENT_TARGET\" \"$DEPLOYMENT_TEMP\""
# eval $SELECT_NODE_VERSION
# exitWithMessageOnError "select node version failed"

因为错误总是被触发。我还不得不使用npm 而不是yarn，因为yarn 使用的节点版本不是正确的
