Github Actions 抛出以下错误:

          chmod +x ./createProdEBAppVersion.sh
          ./createProdEBAppVersion.sh
        fi

    ...

我试过没有 working-directory ，但它没有用。

#!/usr/bin/env bash

aws elasticbeanstalk create-application-version \
--application-name ${{ env.APPLICATION_NAME }} \
--source-bundle S3Bucket="${{ env.AWS_BUCKET }}",S3Key="${{ env.APPLICATION_NAME }}/${{ env.PACKAGE_NAME }}" \
--version-label "${{ env.PACKAGE_NAME }}" \
--description "Application version created from https://github.com/$GITHUB_REPOSITORY/actions/runs/$GITHUB_RUN_ID"
echo "✔ Deployment triggered successfully."

似乎 CI 在查找文件时遇到了问题。如何执行 createDevEBAppVersion.sh ?

Answer 1

您的错误信息是:

/home/runner/work/_temp/9c99fa0d-20da-49ed-a0af-322f274c13ac.sh: line 1: [refs/heads/develop: No such file or directory

它正在尝试执行 [refs/heads/develop和失败。根本原因是您在括号和测试之间缺少一个空格。你要:

if [ "${{ github.ref }}" == "refs/heads/develop" ]; then

(第 5 行也是如此。)

那是因为 if在 bourne shells 中实际上运行一个它评估的命令。虽然它看起来像是在计算一个表达式，但它实际上是在将一个表达式传递给一个名为 [ 的命令。 .

% ls -Flas /bin/\[
 8 -rwxr-xr-x  1 root  wheel  22704 May  4  2019 /bin/[*

这通常是指向 /bin/test 的符号链接(symbolic link)(或硬链接(hard link))。 ，在某些 shell 中，如 bash 和 zsh， [实际上将是一个内置的shell:

% which '['
[: shell built-in command

但它的行为仍然像一个命令，从语法上讲，它需要空格。因为:

if [ true ]; then ...

运行 [命令(或 shell-builtin)评估 /bin/true命令。和

if [true ]; then ...

尝试运行不存在的 [true命令。
