ImportError: DLL load failed: 지정된 모듈을 찾을 수 없습니다.

我做了几件事，但我不知道为什么模块不可用

1. 我安装了quandl 如下：

pip install quandl

1. 我在python下做了我的代码

import quandl

quandl.ApiConfig.api_key = '@@@@@@@@@@@@@@'
data = quandl.get('BCHARTS/BITFLYERUSD', start_date='2019-03-07', end_date='2020-05-02')

print(data)

1. 我调用我的 pthon 代码

python -m myPythonCode

然后，我看到了错误。

所以我删除并安装了，但失败了。

所以我安装如下：

pip3 install quandl

这仍然失败。

如果卸载 quandl 然后调用我的 python 代码，我会看到错误：

ModuleNotFoundError: No module named 'quandl'

请帮帮我。

当错误与 DLL 相关时，很多时候可以通过安装最有可能丢失的 Microsoft Visual C++ Redistributable 来解决。
