Python使用googletrans报错的解决方法

问题

最近在工作中发现了一个问题，Python代码一直用着免费的Google翻译API插件googletrans，这两天突然就报错了：

Traceback (most recent call last):
File "xxx.py", line 5, in <module>
result = translator.translate("Result from google translator", dest="zh-CN")
File "/usr/lib/python3.4/site-packages/googletrans/client.py", line 172, in translate
data = self._translate(text, dest, src)
File "/usr/lib/python3.4/site-packages/googletrans/client.py", line 75, in _translate
token = self.token_acquirer.do(text)
File "/usr/lib/python3.4/site-packages/googletrans/gtoken.py", line 180, in do
self._update()
File "/usr/lib/python3.4/site-packages/googletrans/gtoken.py", line 59, in _update
code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
AttributeError: 'NoneType' object has no attribute 'group'

单独写个测试：

from googletrans import Translator;

if __name__ == "__main__":
translator = Translator()
result = translator.translate("Result from google translator", dest="zh-CN")
print(result.text)

result = translator.translate("使用免费谷歌自动翻译API", dest="en")
print(result.text)

曝出同样的错误。

解决办法

谷歌爸爸的翻译API接口进行了改动，让一票翻译的软件包不好使了。问题影响是全球性的，所以GayHub上很快就跟进讨论，并提交代码修复。代码在手，方案我有，三步操作让googletrans重新好使：

• 卸载已有的googletrans;

• git克隆最新的代码；

• 安装包。

打开终端，三个命令搞定问题：

pip uninstall googletrans
git clone https://github.com/BoseCorp/py-googletrans.git
cd ./py-googletrans && python setup.py install
