VSCode Marketplace 扩展：损坏的 ZIP：未找到中央目录记录签名的结尾

编程问答 2022-05-26

问题描述

我正在尝试在安装了 VSCode 服务器的 Linux VM 上安装使用 wget 从 Marketplace 下载的 VSIX 软件包，但出现以下错误：

$ wget -nv https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage -o vspackage.vsix
$ code --install-extension vspackage.vsix
Installing extensions on SSH: boozy-olive-harrier...
Corrupt ZIP: end of central directory record signature not found
Failed Installing Extensions: vscode-remote://ssh-remote%2Bboozy-olive-harrier/root/vspackage.vsix

在 Windows 上使用 Firefox 下载文件并使用 VSCode 客户端 (ref) 中的“从 VSIX 安装...”按钮按预期工作。

我使用的网址是：https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage

我比较了下载文件的 md5sum，如果我从 Windows 或 Linux 下载文件，我没有得到相同的结果：

Linux 虚拟机：

  • wget
$ wget -nv https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage
2021-02-09 16:50:08 URL:https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage [1270960/1270960] -> "vspackage" [1]
$ du -sk vspackage
1244    vspackage
$ md5sum vspackage
10f6bdb1151a954a702f8a6db6f3bd52  vspackage

Windows：

> certutil.exe -hashfile .\llvm-vs-code-extensions.vscode-clangd-0.1.9.vsix MD5
MD5 hash of .\llvm-vs-code-extensions.vscode-clangd-0.1.9.vsix:
74f82f716616796157bde8008c8e5a45
CertUtil: -hashfile command completed successfully.
  • Powershell
> Invoke-WebRequest https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage -OutFile vspackage
> Get-ChildItem .\vspackage | % {[int]($_.length / 1kb)}
1383
> certutil.exe -hashfile .\vspackage MD5
MD5 hash of .\vspackage:
74f82f716616796157bde8008c8e5a45
CertUtil: -hashfile command completed successfully.

即使下载地址相同，下载文件的哈希值也不相同。

似乎我在 Linux 上遗漏了几个字节，这可以解释 Corrupt ZIP 错误。

有人明白我在这里缺少什么吗？

解决方法

我试过你提供的网址

$ wget -nv https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage
2021-02-11 09:04:22 URL:https://marketplace.visualstudio.com/_apis/public/gallery/publishers/llvm-vs-code-extensions/vsextensions/vscode-clangd/latest/vspackage [1270960/1270960] -> "vspackage"

让我们看看vspackage是什么

$ file vspackage
vspackage: gzip compressed data,max speed,from FAT filesystem (MS-DOS,OS/2,NT),original size modulo 2^32 1416661

那不是 zip，而是压缩的 gzip 文件。让我们解压缩

$ mv vspackage vspackage.gz
$ gunzip -v vspackage.gz
vspackage.gz:    10.3% -- replaced with vspackage

现在 vspackage 是什么？

$ file vspackage
vspackage: Zip archive data,at least v2.0 to extract

最后是一个 zip 文件。
