當我的data_logger.py嘗試“導入保管箱”時出現此錯誤

pi@raspberrypi:~/cb_logging/bin $ sudo ./data_logger.py

我不知道怎么了。 有人可以幫忙嗎？

Answer 1

您在安裝的請求模塊中遇到問題。 首先升級pip，然后嘗試重新安裝請求。

sudo apt-get install --only-upgrade python-pip
sudo pip uninstall requests
sudo pip install requests

不知道是否為時已晚（它可能會對其他人有所幫助），但是我在Dropbox上遇到了同樣的問題，並能夠通過以下方法解決：

pip install urllib3 --upgrade

或專門針對我而言（差異腳本版本）：

pip2.7 install urllib3 --upgrade
