构建和 运行 时出现 dotnet new blazor 错误
dotnet new blazor error when build and run
我有 dotnet-sdk-3.0.100-preview3-010431-win-x64 zip 二进制文件并将其解压缩到 C:\dotnet 并将此路径添加到用户变量路径。
我之前在该路径中有 dotnet 2.2，我将其删除并粘贴新版本 (preview3-010431) 以创建一个 blazor 项目。
dotnet 可以正确创建和 运行 webapp 项目但不能创建 blazor。
首先我执行了这个命令：
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::0.9.0-preview3-19154-02
当我运行:
dotnet new blazor -o WebApplication1
cd WebApplication1
没关系。但是 dotnet build 不起作用，我收到错误消息：

我删除了C:\Users\sap-komaei.CII.nuget\packages中的所有包，但错误存在。我也删除了C:\Users\sap-komaei.CII.dotnet中的所有文件和文件夹，但存在错误。
我运行之后：
dotnet new -i Microsoft.AspNetCore.Blazor.Templates
然后构建，我得到这个错误：

是
我想通了。
为了构建 blazor 模板，我们必须同时安装 dotnet core v3 预览版和最新的 2.2 版本。我无法在工作电脑上安装任何应用程序。所以我用便携版。
我的解决方案：
复制E:\My Pro\DotNetCore\dotnet-sdk-2.2.105-win-x64\sdk.2.105文件夹到我的sdk安装路径(E:\dotnet\sdk)
复制E:\My Pro\DotNetCore\dotnet-sdk-2.2.105-win-x64\shared\Microsoft.NETCore.App.2.3文件夹到E:\dotnet\shared\Microsoft.NETCore.App.
添加 E:\dotnet\ & E:\dotnet\host\fxr.0.0-preview3-27503-5\ & E:\My Pro\VS Code.32.1 \ 到用户路径变量。
将 E:\dotnet\ 添加到 DOTNET_ROOT 变量。
