找不到SSH Shell命令（composer，npm）

Question

我的服務器是使用whm和cpanel在a2hosting上的Linux經銷商計划。

我的項目是PHP Laravel。

該項目將生成，然后使用Copy Files Over SSH任務Copy Files Over SSH復制到服務器。

問題是，當我嘗試在composer install和npm install之后添加SSH任務時，出現錯誤。 它使用與文件復制任務相同的SSH連接和密鑰。 諸如cd和ls之類的東西都可以工作。

當我在本地使用相同的用戶名和相同的私鑰並運行composer install它和npm install起作用。 在運行composer和npm之后，該站點可以很好地加載，但是我希望此操作可以自動化，因此我不必手動運行這些命令。

這是我的inline script ：

composer install

我的錯誤如下所示：

Answer 1

當您通過SSH手動登錄時可以執行命令，但是不能通過Azure腳本執行相同的命令。 這可能意味着您的管道腳本無法加載~/.bashrc或預期的$PATH值，以便能夠找到composer命令。 您需要通過手動運行echo $PATH並通過管道腳本來確保管道腳本包含正確的$PATH值，然后比較該值，或者您可以嘗試放置composer二進制文件的完整路徑，可以通過以下方式手動獲取它：執行which composer ， npm 。

更新：正如您提到的那樣，$ PATH存在問題，您可以在正在使用的bash腳本中手動定義它，如下所示：

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