我收到此错误（ModuleNotFoundError: No module named 'pandas'），即使我安装了它

Question

所以我在我的 mac 上使用 visual studio 代码，我正在尝试运行 python 代码，但我在安装库时一直遇到问题。 每当我运行代码时，我都会得到这个

(base) reema@Reemas-MacBook-Pro-2 ~ % /usr/local/bin/python3 "/Users/reema/Desktop/import pandas as pd.py" Traceback (most recent call last): File "/Users/reema/Desktop/import pandas as pd.py", line 1, in import pandas as pd ModuleNotFoundError: No module named 'pandas'

即使当我再次安装它时它说这个

`(base) reema@Reemas-MacBook-Pro-2 ~ % pip install pandas
Requirement already satisfied: pandas in ./opt/anaconda3/lib/python3.8/site-packages (1.4.2)
Requirement already satisfied: pytz>=2020.1 in ./opt/anaconda3/lib/python3.8/site-packages (from pandas) (2021.1)

Requirement already satisfied: six>=1.5 in ./opt/anaconda3/lib/python3.8/site-packages (from python-dateutil>=2.8.1->pandas) (1.15.0)`

Answer 1

这是因为您的 pandas 已安装在 anaconda 环境而不是基础环境中（您使用基础 python 解释器运行代码）。

使用快捷键“Ctrl+Shift+P”并输入“Python: Select Interpreter”来选择正确的解释器。

1. 您可以选择 anaconda 然后运行代码。
2. 如果要在基础 python 解释器中运行代码。 使用命令deactivate env_name或打开一个新终端 window 并使用命令“pip install pandas”安装此 package
