Question

我与MySQL数据库建立连接时遇到问题。

我有以下代码：

Public Sub BuildAssetFoldersStructure()
    Debug.WriteLine(vbCr & "Creating Assets folders from DevForm.AssetsFolderStructure")
    Dim n As TreeNode
    For Each n In DevForm.AssetsFolderStructure.Nodes
        PrintRecursive(n)
    Next

End Sub


Private Sub PrintRecursive(ByVal n As TreeNode)

    Dim dpath As String = Nothing
    Dim finalNodeText As String = Nothing

    If n.Text.Substring(0, 1) = "[" Then

        For Each col In New List(Of String) From {"red", "white", "blue"}

            dpath = Path.Combine(My.Settings.fileAssetsPath, n.Parent.FullPath & "\" & col)
            System.Diagnostics.Debug.WriteLine("Creating: " & dpath)
            Directory.CreateDirectory(dpath)
        Next

    Else
        dpath = Path.Combine(My.Settings.fileAssetsPath, n.FullPath)
        System.Diagnostics.Debug.WriteLine("Creating: " & dpath)
        Directory.CreateDirectory(dpath)
    End If

    Dim aNode As TreeNode
    For Each aNode In n.Nodes
        PrintRecursive(aNode)
    Next

End Sub

此代码生成以下错误：

当我尝试：pip安装mysql时，出现以下错误：

connection_string = "mysql+mysqldb://{user}:{password}@{host}/{database}?charset=utf8mb4".format(
    user=config[db]["user"], password=config[db]["password"],
    host=config[db]["host"], database=config[db]["database"])

sqlalchemy_engine = sqla.create_engine(connection_string, convert_unicode=True)

说实话，我不知道这里发生了什么（pip install mysql-python生成完全相同的错误，以及pip install oursql和pip install mysqlclient）。我发现cc是C编译器。我已经安装了（gcc）。有人可以帮忙吗？
