Chrome扩展程序：无法加载JavaScript文件 [英] Chrome extension: Could not load javascript file

问题描述

我发布了另一个关于我的Chrome扩展程序的问题 by Rob Wu

这里的问题在于，您已经将压缩的CRX文件上传到您的ZIP文件，而不是您的扩展程序源代码。您应该上传包含您的扩展程序根目录的ZIP文件。既然你已经包含了 manifest.json 文件，那么Web Store在你尝试安装扩展之前并没有注意到任何错误，因为清单写得很好，但是当Chromes尝试访问已声明的文件时，它会失败并返回错误，因为这些文件不存在。

通过Chrome网上应用店开发人员信息中心的上传页面进行引用：

上传一件商品：

• 上传您的商品目录的 ZIP文件，而不是打包的CRX文件。 更多信息）。


• 阅读有关创建和打包应用程序的文档。


• 需要更多帮助？请查阅 Chrome网上应用店开发者文档。

因此，您应该为您的扩展程序根目录创建一个 ZIP 文件，其中包含 strong>您的扩展的文件。您的ZIP文件应该如下所示：

I have posted another question regarding my Chrome extension here.
But I have one more question about extensions themselves. I only need a content script for the modification of the Tumblr-Dashboard, no background page or something else, right?

Here is the manifest.json file:

{
    "name": "Tumblr - Tiled Dashboard",
    "version": "0.0.54",
    "manifest_version": 2,
    "description": "This extension modifies the look of your Tumblr dashboard.",
    "icons": {
        "16": "images/icon_16.png",
        "48": "images/icon_48.png",
        "128": "images/icon_128.png"
    },
    "content_scripts": [
        {
            "matches": [ "*://*.tumblr.com/dashboard" ],
            "css": [ "styles.css" ],
            "js": [ "jquery-2.1.3.min.js", "masonry.min.js", "code.js" ]
        }
    ],
    "homepage_url": "mypage",
    "author":  "myname"
}

To start, I ask if this is alright? I have read a lot about the manifest.json file and everything seems to work fine when I try out the extension locally. But when I pack the extension and upload it, there are two problems:

1. I cannot find the extension when I search for it
2. When I use the link to find the extension, and I want to install it (tried that on 2 different PCs), I get an error, telling me that the jquery-2.1.3.min.js file could not be loaded. I therefore changed the order of my JavaScript files to test if it was a problem related to the jQuery file, but having masonry.min.js as the first file in the array resulted in the same error.

Why does this happen? Is the manifest.json file ok? Do I need some special permissions?

Edit: This is a screenshot of when I try to install the extension from the Chrome Web Store (where I also can't find it by search).

I took a look inside your extension's ZIP file before downloading it, and the result was the following:

The problem here, is that you've uploaded a packed CRX file inside of your ZIP file, instead of your extension source code. You should instead upload a ZIP file containing your extension's root. Since that you're including the manifest.json file, the Web Store doesn't notice anything wrong until you try to install the extension, because the manifest is well written, but when Chromes tries to access the files declared, it fails and returns an error, because those files do not exist.

Quoting from the upload page of the Chrome Web Store Developer Dashboard:

Uploading an item:

• Upload a ZIP file of your item directory, not a packaged CRX file.
• Include a well-designed product icon in your manifest (more info).
• Read the documentation about creating and packaging apps.
• Need more help? Check out the Chrome Web Store developer documentation.

So, you should create a ZIP file of your extension's root directory, containing all the files of your extension. Your ZIP file should then look like the following:
