离子2覆盖scss变量

Question

我尝试覆盖Ionic 2 scss变量，使我的变量放入以下代码中变小：

Public Sub EncryptAndSign(outputStream As Stream, unencryptedData As Byte())
    Using encryptedOut As Stream = ChainEncryptedOut(outputStream)
        Using compressedOut As Stream = ChainCompressedOut(encryptedOut)
            Dim signatureGenerator As PgpSignatureGenerator = InitSignatureGenerator(compressedOut)
            Using literalOut As Stream = ChainLiteralOut(compressedOut, unencryptedData)
                WriteOutputAndSign(compressedOut, literalOut, unencryptedData, signatureGenerator)
            End Using
        End Using
    End Using
End Sub

Private Shared Function ChainLiteralOut(compressedOut As Stream, data As Byte()) As Stream
    Dim pgpLiteralDataGenerator As New PgpLiteralDataGenerator()

    Return pgpLiteralDataGenerator.Open(compressedOut, PgpLiteralData.Utf8, "enc_" & Now.Ticks, Now, data)
End Function

Private Shared Sub WriteOutputAndSign(compressedOut As Stream, literalOut As Stream, inputData As Byte(), signatureGenerator As PgpSignatureGenerator)
    Dim length As Integer = inputData.Length
    Dim buf = inputData

    literalOut.Write(buf, 0, length)
    signatureGenerator.Update(buf, 0, length)

    signatureGenerator.Generate().Encode(compressedOut)
End Sub

可以找到芯片API here

HTML：

$chip-button-border-radius: 20%;
$chip-button-size: 20px;
$chip-icon-size: 20px;

筹码没有改变。

我错过了什么吗？
