linux - 未找到 SSH Shell 命令(composer、npm)

Question

我的服务器是使用 whm 和 cpanel 的 a2hosting 的 linux 经销商计划。

我的项目是 PHP Laravel。

项目构建，然后使用 Copy Files Over SSH 任务，我能够将文件复制到我的服务器。

问题是，当我尝试为 composer install 和 npm install 添加 SSH 任务时，出现错误。它使用与文件复制任务相同的 SSH 连接和 key 。 cd 和 ls 之类的东西可以工作。

当我在本地使用相同的用户名和相同的私钥并运行 composer install 时，它和 npm install 一样有效。运行 composer 和 npm 后，网站加载正常，但我希望它是自动化的，这样我就不必手动运行这些命令。

这是我的内联脚本:

composer install

我的错误是这样的:

Answer 1

因为您可以在通过 SSH 手动登录时执行命令，但不能通过 Azure 脚本执行相同的命令。这可能意味着您的管道脚本无法加载 ~/.bashrc 或预期的 $PATH 值，以便能够找到 composer 命令。您需要通过手动运行 echo $PATH 并通过管道脚本确保您的管道脚本包含正确的 $PATH 值，然后比较该值，或者您可以尝试将composer 二进制文件的完整路径，您可以通过执行 which composer 手动获取它，对于 npm 也是如此。

更新:正如您提到的 $PATH 有问题，您可以在您使用的 bash 脚本中手动定义它，如下所示:

export PATH=/my/missing/path:$PATH
