Elastic Beanstalk上的「npm install」失敗，除非手動執行

Question

我已經有了一個PHP應用程序的Elastic Beanstalk環境。我想在應用程序部署完成後運行npm install。

node和npm都安裝通過部署CONFIGS在服務器上。我已經定義了一個容器命令來簡單地cd到正確的目錄，然後運行npm install，但它的always失敗，出現相同的錯誤。

如果我手動執行npm install，一切都被完美地安裝。

我該如何去調試呢？

    01_mkdir_webapp_dir: 
     # use the test directive to create the directory 
     # if the mkdir command fails the rest of this directive is ignored

     command: 'ls -la /home/webapp'

對於任何人遇到一個PHP彈性青苗例如這個問題，這裏就是幫助我度過這次難關：

1）如果你在Amazon Linux實例上運行，做一個yum install nodejs會給你一個超級老版本這很可能與許多事情不相容。我不得不在我的.ebextensions目錄中添加一個腳本，並從我的一個配置中執行它以安裝更新版本的nodejs。下面是該腳本的副本：

#!/bin/bash 

hash_file="/tmp/nodejshash" 

check_if_npm_packages_has_to_be_installed() { 
    if [ -f $hash_file ]; then 
     check_if_same_hash 
    else 
     return 0 
    fi 
} 

check_if_same_hash() { 
    hash_new="$(md5sum .ebextensions/bin/install-nodejs.sh 2> /dev/null | cut -d ' ' -f 1)" 
    hash_current="$(cat "$hash_file" 2> /dev/null | cut -d ' ' -f 1)" 

    if [ $hash_new == $hash_current ]; then 
     return 1 
    else 
     return 0 
    fi 
} 

install_node() { 
    if hash nodejs 2> /dev/null; then 
     echo 'nodejs install, add more processing if needed' > /dev/null 
    else 
     curl -sL https://rpm.nodesource.com/setup_6.x | bash - 
     yum install -y nodejs 
    fi 
} 

install_npm_packages() { 
    npm install -g bower 
    npm install -g gulp 
} 

update_current_hash() { 
    echo $hash_new > $hash_file 
} 

install_node 

if check_if_npm_packages_has_to_be_installed; then 
    install_npm_packages 
    update_current_hash 
fi 

2）如果你在默認情況下，微例如，node-sass包採取了一種很長的時間來建立，並最終超時。我將實例大小增加到了t2.small以通過此。

希望這可以幫助別人。
