php - heroku 安装 gd 扩展失败

我正在尝试在 gd 上安装 heroku (或 ext-gd )库。

当我尝试使用 composer 安装它们时(我有如下)

{
    "name": "cool/app",
    "type": "project",
    "require": {
        "ext-gd": "dev-master" (tried also installing "gd":"*", "ext-gd" : "*")
    },
    "license": "2016",
    "authors": [
        {
            "name": "Dario",
            "email": "[email protected]"
        }
    ],
    "minimum-stability": "dev"
}

我有

Problem 1
- The requested PHP extension ext-gd * is missing from your system. Install or enable PHP's gd extension.

因此，尝试从 apt-get ( sudo apt-get install php7-gd ) 安装，但我没有 sudo 权限，因为我不知道 root heroku 密码。

有什么解决办法吗？

为了更好地解释我所做的，这里是整个命令列表

$ heroku run bash

~ $ composer init

而且我无法使用 gd 库，因为 php (Laravel) 说 Call to undefined function App\Http\Controllers\imagecreatefrompng()
如果我从本地计算机运行 composer require ext-gd 我得到

Using version ^0.0.0 for ext-gd
./composer.json has been updated

最佳答案

首先，您必须在本地绑定(bind) php。

1. 步骤
包含在你的 composer.json 中

{
  "require": {
      ..
      "ext-gd": "*",
      ...
   }
}

2. 步骤
更新 Composer

composer update

这需要时间......喝杯咖啡......

3. 步骤
使用 heroku cli 发布

git push heroku master

在发布时注意输出并检查您是否有类似我下面第 5 行的内容，如果一切正常。

1. remote: -----> PHP app detected
2. remote: -----> Bootstrapping...
3. remote: -----> Installing platform packages...
4. remote:        - php (7.3.6)
5. remote:        - ext-gd (bundled with php)
6. remote:        - apache (2.4.39)
7. remote:        - nginx (1.16.0)
8. remote: -----> Installing dependencies...

快乐编码。
