常见问题 三

38，js报错 Uncaught ReferenceError: Base64 is not defined

2.2.6升级到2.3.0后，后台主题编辑页面 打不开 js有报错

Uncaught ReferenceError: Base64 is not defined

解决办法：
找到下面这几个文件

> /vendor/magento/module-email/view/adminhtml/ui_component/design_config_form.xml
> /vendor/magento/module-catalog/view/adminhtml/ui_component/design_config_form.xml
> /vendor/magento/module-backend/view/adminhtml/ui_component/design_config_form.xml
> /vendor/magento/module-swatches/view/adminhtml/ui_component/design_config_form.xml
> /vendor/magento/module-theme/view/adminhtml/ui_component/design_config_form.xml

把

formElement="fileUploader"

替换成

formElement="imageUploader"

都保存后，再重新deploy下 就好了。

39，js报错 Uncaught Error: Script error for: tinymce

2.2.6升级到2.3.0后，后台第三方插件页面打不开，js报错

Uncaught Error: Script error for: tinymce

这是因为2.3.0里，升级tinymce了，升级到tinymce4了。之前旧的tinymce废弃了，所以需要把tinymce的改成tinymce4就行。
比如

define([
    "jquery",
    "tinymce",

改成

define([
    "jquery",
    "tinymce4",

40，Unique constraint violation found

Unique constraint violation found {"exception":"[object] (Magento\Framework\Exception\AlreadyExistsException(code: 0): Unique constraint violation found at /www/wwwroot/newbestyle.com/vendor/magento/framework/Model/ResourceModel/Db/AbstractDb.php:426, Magento\Framework\DB\Adapter\DuplicateException(code: 1062): SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0-8144-product' for key 'GOOGLEOPTIMIZER_CODE_STORE_ID_ENTITY_ID_ENTITY_TYPE', query was: INSERT INTO googleoptimizer_code (entity_id, entity_type, store_id, experiment_script) VALUES (?, ?, ?, ?) at

解决办法：
1, Go to admin -> Stores -> Configuration -> Sales -> Google API section
2, Change the configuration Enable Content Experiments to "No"

41，Argument 4 passed to Magento\Developer\Model\View\Asset\PreProcessor\FrontendCompilation

FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught TypeError: Argument 4 passed to Magento\De
veloper\Model\View\Asset\PreProcessor\FrontendCompilation::processContent() must be an instance of Magento\Framework\View\Asset\File\FallbackContext, in

xt))

这是因为你在developer模式下，并且开启了merge css/js功能，导致出问题了。

解决办法有2种：
1，改成production模式,保留merge css/js功能
2，或者在developer模式下，把dev/js/merge_files和dev/css/merge_css_files设为0，也就是不merge css/js。

42，main.CRITICAL: No linked stock found

2.3.1才有这问题，需要设置多源库存。
常见于分类页面或者产品页面报错 甚至不显示。
解决办法：
1，Try going into Stores > Inventory > Sources and adding in a source. Maybe call it your business name, then fill in a country and zip value.
2，Then, try going into Stores > Inventory > Stocks. Call it "Default Stock" and apply it to all websites (if multi store) and hit save.
设置个默认仓库就行了。

43，Fatal error: Uncaught TypeError: Return value of Magento\Framework\Encryption\Adapter\SodiumChachaIetf::decrypt() must be of the type string

这是m2的一个bug，在2.3.0里特殊环境下会发生。
解决办法：
修改 vendor/magento/framework/Encryption/Adapter/SodiumChachaIetf.php

$plainText = sodium_crypto_aead_chacha20poly1305_ietf_decrypt(
            $payload,
            $nonce,
            $nonce,
            $this->key
        );
        if ($plainText == false)
        {
          return "";
        }
        return $plainText;

44, 2.3.1后台产品列表里无法更新所有产品的属性

2.3.1里产品列表 Select All，再 Update Attributes,发现只更新了20个(当前一页)的产品。而不是所有的产品。
这是2.3.1的一个bug，2.3.2里还没修复。
https://github.com/magento/magento2/issues/22004
https://github.com/magento/magento2/commit/0f29a266256cca24cd7dd1082aa4aa31a3a9eacd

直接修改vendor/magento/module-ui/view/base/web/js/grid/massactions.js
把

if (itemsType === 'excluded' && data.selected && data.selected.length) {
    itemsType = 'selected';
    data[itemsType] = _.difference(data.selected, data.excluded);
}

这几段代码注释掉就行了。

45, 2.2.6/2.2.7版本后台上传 placeholder图片,不能保存

这是m2的一个bug，在2.2.6和2.2.7里出现，在2.3.0里修复了。
如果可以升级版本的话，就直接升级到最新版本。
如果不能升级版本的话，就修改下源代码:
把vendor/magento/module-config/Model/Config.php内容替换为：
https://raw.githubusercontent.com/magento/magento2/be9fa4a73b85022565db991f11dfceeecf40edae/app/code/Magento/Config/Model/Config.php

参考

46, bundle产品和简单(可配置)产品一起购买下单，创建invoice时简单(可配置)产品会丢失，导致支付的金额不对。

这是2.3.1的bug。在2.3.2里修复了。

https://github.com/magento/magento2/issues/22246

https://github.com/magento/magento2/commit/ec2c6ca7df68de9aaccecfb899b102a2a3eaa631

47, Type Error occurred when creating object: Magento\Framework\Locale\Resolver

这是2.3.1的bug。在2.3.2里修复了。

Type Error occurred when creating object: Magento\\Framework\\Locale\\Resolver, Return value of Magento\\Framework\\Encrypt

ion\\Adapter\\SodiumChachaIetf::decrypt() must be of the type string, boolean returned \[\]

见
https://github.com/magento/magento2/issues/19590
修改了 vendor/magento/framework/Encryption/Adapter/SodiumChachaIetf.php

public function decrypt(string $data): string
    {
        $nonce = mb_substr($data, 0, SODIUM_CRYPTO_AEAD_CHACHA20POLY1305_IETF_NPUBBYTES, '8bit');
        $payload = mb_substr($data, SODIUM_CRYPTO_AEAD_CHACHA20POLY1305_IETF_NPUBBYTES, null, '8bit');

        try {
            $plainText = sodium_crypto_aead_chacha20poly1305_ietf_decrypt(
                $payload,
                $nonce,
                $nonce,
                $this->key
            );
        } catch (\SodiumException $e) {
            $plainText = '';
        }

        return $plainText !== false ? $plainText : '';
    }

48, Front controller reached 100 router match iterations

Exception #0 (LogicException): Front controller reached 100 router match iterations

这一般是2个插件同名，导致冲突了。
比如2个blog插件，Magefan_Blog和MGS_Blog，这2个的frontend/routes.xml 都是blog。
并且都重写了前台路由:

MGS\Blog\Controller\Router
Magefan\Blog\Controller\Router

导致冲突了。禁用一个，保留一个就行。

49, Session data file is not created by your uid

Warning: SessionHandler::read(): Session data file is not created by your uid

这个是权限问题，php的session默认放在/tmp下的，给/tmp权限即可。
或者m2里可以指定session存放路径,在app/etc/env.php里添加：

'session' => [
        'save' => 'files',
        'save_path' => '/var/www/toncen-test/var/session'
    ],

50，Elasticsearch pagination 分页有问题

这是2.3.3的一个bug。
见
https://github.com/magento/magento2/issues/25038
里面有解决方案

51，apache下403 Forbidden

Forbidden

You don't have permission to access /webfiles on this server. Server unable to read htaccess file, denying access to be safe

这是权限问题，需要给magento2根目录755的权限
sudo chmod 755 /var/www/magento2
https://stackoverflow.com/questions/27890751/magento-new-host-403-forbidden-server-unable-to-read-htaccess-file

52，Magento\Framework\View\Page\Config\Renderer::canTypeBeFont() must be of the type string, null given

PHP message: PHP Fatal error: Uncaught TypeError: Argument 1 passed to Ma
gento\Framework\View\Page\Config\Renderer::canTypeBeFont() must be of the type string, null given, called in /home/www/helakauppa.mgtdev2.iggo.f
i/vendor/magento/framework/View/Page/Config/Renderer.php on line 347 and defined in /home/www/helakauppa.mgtdev2.iggo.fi/vendor/magento/framewor
k/View/Page/Config/Renderer.php:426

这是因为layout渲染html的时候发现没有找到对应的css或者js文件。一般多发生于新安装的插件。
需要deploy下。

53，Call to a member function getIsResizeEnabled() on null

PHP message: PHP Fatal error: Uncaught Error: Call to a member function getIsResizeEnabled() on null in vendor/magento/module-backend/view/adminhtml/templates/media/uploader.phtml:16

这个在v2.3.x版本里会出现，是因为你安装的某个插件有调用上传图片的类，少传了一个参数。
你肯定首先要找到插件的代码，一般类似这样

$this->addChild('uploader', 'Magento\Backend\Block\Media\Uploader');

你改成

$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$imageUploadConfigDataProvider = $_objectManager->get(\Magento\Backend\Block\DataProviders\ImageUploadConfig::class);
$this->addChild(
            'uploader',
            \Magento\Backend\Block\Media\Uploader::class,
            ['image_upload_config_data' => $imageUploadConfigDataProvider]
        );

这样就行了。
