self.method = environ['REQUEST_METHOD'].upper() 的報錯，在百度上找了一圈沒有找到原因，具體找了一下兩個網址：

https://stackoverflow.com/questions/35607350/python-3-4-3-bottle-with-cgi-environrequest-method

之前一直是運行很正常的，但是不知道爲什麼這次發版就不行了。

到了最後發現是不知道爲啥項目跑出來虛擬空間的範圍。

在外面沒有相應的包。

所以：

因爲沒有安裝好相應的包。

之前都安裝到了虛擬空間裏面，但是這次不知道什麼原因，虛擬空間的都不管用了。

然後再外面包都給安裝好了。
