VS Code启动<conda active base>错误信息

Question

我刚开始在 Visual Studio Code 上学习 Anaconda。以前，我只使用 Python 作为解释器。下载 Anaconda 并打开 VS Code 后，我总是遇到以下错误消息。

PS C:\Users\user\Documents\PythonLearn> conda activate base
conda : The term 'conda' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the 
name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ conda activate base
+ ~~~~~
    + CategoryInfo          : ObjectNotFound: (conda:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

---

我已经尝试安装并重新安装 anaconda 并通过设置环境变量，但错误消息仍然存在。我使用的步骤如下。

我的安装过程

1. 下载蟒蛇

   • 选择一：只有我（推荐）

   • 选择2（高级）： Registered Anaconda3 for the system Python 3.9

2. 将anaconda加入环境变量

   • 以管理员身份运行“Anaconda Prompt (anaconda3)”

   • 奔跑

     where conda

   • 将目录添加到环境变量

   

3. 将解释器路径添加到 VS 代码中

   

4. 通过 .py 文件进行测试

   • 测试#1 - 蟒蛇：

     print("Hello, world")

   

   • 测试#2 - 图书馆：

   import matplotlib.pyplot as plt
   import matplotlib as mpl
   import numpy as np
   x = np.linspace(0, 20, 100)
   plt.plot(x, np.sin(x))
   plt.show()
   

   对于测试#2，终端产生如下错误信息

调试尝试

1. 以前的可能解决方案：更新环境变量

   我重新安装并更新了新路径。命令提示符仍然无法识别系统中的 conda。然而，系统检测到 Python。

   

2. 测试 Anaconda 是否正常工作

   我测试了安装的Anaconda文件是否可以在Anaconda所在的目录中检测到版本。系统确实检测到Anaconda的安装版本。

结尾说明/更新

有没有人遇到这个错误的类似问题？您推荐的解决方案是什么？

提前感谢您的回复。如果我找到解决方案，我会及时通知您。

更新#1： 重启，重新打开，重新选择路径，更新 我已经通过 Anaconda 终端中的

conda update conda

和

conda update anaconda

更新了 Anaconda。同时重新启动计算机并重新打开终端。尽管如此，每当我打开 VS 代码时，错误代码仍然存在（下面的错误代码）。

Answer 1

你是否在 VS Code 仍然打开时安装了 conda？

VS Code 终端不更新它的 PATH，PATH 的初始化在终端启动时进行，CMD 也一样。

我唯一的解决方案是重新打开 VS Code 或在导航栏的终端部分启动一个新终端，因为您已经在 Windows 上安装了 conda 并且 CMD 确认了它

解释器路径定期更新。

Answer 2

解决方案： 完全卸载，使用高级选择重新安装

大声呼唤 Gren Man 的解决方案。步骤如下

1. 干净卸载anaconda

   • 'conda 安装 anaconda-clean' --> 运行 'anaconda-clean --yes'
   • 然后进入“添加或删除程序”-->卸载Anaconda3-->重启电脑

2. 重新安装

   • 选择下载包->以管理员身份运行
   • 选择“将Anaconda3添加到我的PATH环境变量”

3. 测试和验证

   • 运行 print("Hello, world") --> 检查 Python [通过]
   • 运行库测试（见上文）--> Checking Library [Passed]

附加说明

选择“Add PATH”选项，将如下路径添加到系统中。 VS Code 可以发现它们。 添加的路径与调用

where conda

不同，自己手动添加到环境变量中。
