Question

我正在尝试使用blazor和.NET构建项目，但是在运行此命令后

dotnet new blazorwasm -o blazor-web

我知道了

Creating this template will make changes to existing `files:


`Overwrite   ./App.razor


`Overwrite   ./blazor-web.csproj


Rerun the command and pass --force to accept and create.

因此，在构建它之后，我将使用以下命令对其进行编译

dotnet build

但是我遇到了这个错误

Microsoft (R) Build Engine version 16.5.0+d4cbfca49 for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.
MSBUILD : error MSB1003: Specify a project or solution file `The current working directory does not contain a project or solution file`

任何帮助将不胜感激。

Answer 1

df1 = pd.DataFrame({
        'A':['s'],
         'B':[50],
         'C':[70]
})


df2 = pd.DataFrame({
        'D':list('abcdef'),
         'E':[4,5,4,5,5,4],
         'F':[7,8,9,4,2,3],

})

df1 = df1.reindex(df2.index, method='ffill')
df = pd.concat([df1, df2], axis=1)
print (df)
   A   B   C  D  E  F
0  s  50  70  a  4  7
1  s  50  70  b  5  8
2  s  50  70  c  4  9
3  s  50  70  d  5  4
4  s  50  70  e  5  2
5  s  50  70  f  4  3

您尝试从错误的文件夹构建项目：

MSBUILD : error MSB1003: Specify a project or solution file `The current working directory does not contain a project or solution file`

创建blazor项目，但在构建时出现问题
