asp.net-core - 从 Visual Studio 2015 发布 asp.net 5 时出现 "Path too long"

标签 asp.net-core asp.net-core-mvc dnu

这似乎是一个常见问题，我发现了几个 Stack Overflow 问题，但它们似乎都与 MSBuild 有关。

我尝试通过在 Visual Studio 中右键单击我的 asp.net 5 rc1 项目并调用基于文件系统的发布配置文件来进行发布。

它的设置如下所示:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <WebPublishMethod>FileSystem</WebPublishMethod>
        <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
        <LastUsedPlatform>Any CPU</LastUsedPlatform>
        <SiteUrlToLaunchAfterPublish />
        <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
        <ExcludeApp_Data>False</ExcludeApp_Data>
        <CompileSource>False</CompileSource>
        <_DefaultDNXVersion>dnx-clr-win-x86.1.0.0-rc1-final</_DefaultDNXVersion>
        <UsePowerShell>True</UsePowerShell>
        <IISCommand>web</IISCommand>
        <WebRoot>wwwroot</WebRoot>
        <WwwRootOut>wwwroot</WwwRootOut>
        <IncludeSymbols>False</IncludeSymbols>
        <Native>False</Native>
        <IgnoreDNXRuntime>False</IgnoreDNXRuntime>
        <publishUrl>C:\Source\CCollections\artifacts\bin\CCollections.Client.Web.Angular\Release\PublishOutput</publishUrl>
        <DeleteExistingFiles>False</DeleteExistingFiles>
    </PropertyGroup>
</Project>

这会产生以下输出:

C:\Source\CCollections\src\CCollections.Client.Web.Angular>

我认为我的问题在这里:C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\

我需要使用较短的路径，例如 C:\Temp。

我已经尝试了其他堆栈溢出答案中的一些建议。

添加<AspnetCompileMergeIntermediateOutputPath>c:\shortPath\</AspnetCompileMergeIntermediateOutputPath>到个人资料似乎没有帮助。

添加<IntermediateOutputPath>..\Temp</IntermediateOutputPath>似乎也不起作用。

我猜这是因为这些设置被 MSBuild 拾取，而不是 dnu 发布。

那么如何告诉 dnupublish 在 C:\Temp 而不是我的 appdata 目录中构建包？

更新:查找罪魁祸首:我认为超出路径限制的文件不在上述日志中，并且仅记录成功的副本。为了检验这个假设:

  1. 我通过手动运行 dnupublish 部署到 c:\temp
  2. 已将文件从 c:\temp 复制到 C:\Users\Christopher\AppData\Local\Temp\PublishTemp

  3. 运行脚本以递归方式迭代所有文件并输出超过 248 个字符的路径长度。结果:

    C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\net451\Microsoft.Extensions.Configuration.FileProviderExtensions.dll

    文件路径长:249 个字符

    C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\netcore50\Microsoft.Extensions.Configuration.FileProviderExtensions.dll

    文件路径长:252 个字符

最大的文件夹为 191 个字符，文件为 252 个字符，因此分别不超过 240 和 260 个字符。

无论如何，我如何告诉 Visual Studio 2015 使用“C:\temp”作为其临时目录，而不是我的配置文件的临时目录？

最佳答案

将临时输出更改为具有较短路径名的路径。

  1. 从以下位置打开 .\Properties\PublishProfiles 中的目标 .pubxml 文本编辑器。
  2. 更改或添加名为 PropertyGroup 下的 PublishOutputPathNoTrailingSlash 并设置 值到您想要的路径。
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <PublishOutputPathNoTrailingSlash>C:\Temp\Publish</PublishOutputPathNoTrailingSlash>
  </PropertyGroup>
</Project>
