安装 Anaconda 后 Pycharm 中的 csv 导入错误

Question

I need to install Anaconda for another project while I use Pycharm regularly. However, after I installed Anaconda, if I hit the run button on Pycharm for a python file (I'm using python 3.7.4), there is an import error. There was no problem before Anaconda was installed for the same code.

To illustrate, under the parent folder I created a folder named "io" (which is the same as built-in module) and the python file named "testandtest.py". The directory structure is like this:

• test_IO_error/
  • init .py
  • io/
    • init .py
  • testandtest.py

The code of "testandtest.py" is as below:

import csv
def foo():
    print ("This is a test!")

After I hit "run" button for testandtest.py in Pycharm, there is an error message:

Fatal Python error: init_sys_streams: can't initialize sys standard streams AttributeError: module 'io' has no attribute 'OpenWrapper' Current thread 0x00046ccc (most recent call first): Process finished with exit code -1073740791 (0xC0000409)

I assume this problem is because when importing csv , some files in csv module needs to import the built-in module io , but instead import the io module in the current folder, which of course does not have an attribute 'OpenWrapper'. But isn't it the case that python 3 is using absolute import always?

There is no problem if I run the function foo in console of Pycharm.

This problem only happened when run the code using the "run" button in Pycharm software.

Answer 1

After searching many answers on line. I find a fix.

This is obviously a module shadowing issue. However, I don't want to change the folder name from io to another one.

the fix is: go to Run --> Edit Configurations then uncheck

• Add content roots to PYTHONPATH
• Add sources roots to PYTHONPATH

Similar Problem was fixed before.
