錯誤，試圖安裝cassandra驅動程序使用python

Question

我想安裝cassandra驅動程序使用python（在Windows），但它失敗，以下例外。可能有人請幫助我在此，

我自己也嘗試在以下位置&其同樣的錯誤中提到的手工安裝過程， http://datastax.github.io/python-driver/installation.html

Answer 1

我能夠成功安裝卡桑德拉驅動程序使用下面的命令，

命令：

pip install cassandra-driver --install-option="--no-cython" 

下面是完整的安裝日誌（僅供參考）：

Answer 2

卡桑德拉驅動器顯然需要cython。所以pip install cython會解決這個問題。

Answer 3

我使用以下命令在遠程安裝了cqlsh客戶機，

sudo apt-get install build-essential python-dev python-pip libev4 libev-dev 
sudo apt-get install cython3 
sudo pip install cassandra-driver 
sudo pip install cassandra-driver --install-option="--no-cython" 
sudo pip install cqlsh; (Or cqlsh==5.0.3) 
export CQLSH_NO_BUNDLED=TRUE 
cqlsh 192.168.0.330 --cqlversion="3.4.2"
