TypeError: 'type' object is not iterable
资料方案
- 方法1
查找资料说可以如下解决：
sudo pip uninstall enum
sudo pip install enum34
但是该命令仍然会报上述错误。
- 资料2
手动移除
- Removed enum from "/usr/lib/python2.7/dist-packages":
rm -rf enum* - When I tried to install enum34 using "pip install enum34" I still run into the same error from cryptography: "TypeError: 'type' object is not iterable". (I think its because there is a copy of enum present under "/usr/local/lib/python2.7/dist-packages" as well.
- Next I removed cryptography from "/usr/lib/python2.7/dist-packages": rm -rf cryptography*
- Now try running "pip uninstall enum", it works.
- Then install enum34: pip install enum34
- Then install cryptography again: pip install cryptography
最终解决
-
command+space按键打开搜索栏，输入/library打开资源库 - 进入
/Library/Python/2.7目录中发现只有site-packages目录，且里面有enum相关的文件，应该是之前自己通过pip install enum命令添加的 - 输入
sudo rm -rf enum* - 安装enum，
pip install enum34
