在Spyder上安装模块

Question

我正在尝试在spyder独立版本上安装quandl模块。

我尝试在 iPhyton 控制台上运行 !pip install quandl 命令，但收到此输出

Python path configuration:
  PYTHONHOME = '/Applications/Spyder.app/Contents/Resources'
  PYTHONPATH = (not set)
  program name = '/Users/gianluca/miniconda3/bin/python'
  isolated = 0
  environment = 1
  user site = 1
  safe_path = 0
  import site = 1
  is in build tree = 0
  stdlib dir = '/Applications/Spyder.app/Contents/Resources/lib/python3.11'
  sys._base_executable = '/Users/gianluca/miniconda3/bin/python'

  sys.base_exec_prefix = '/Applications/Spyder.app/Contents/Resources'
  sys.platlibdir = 'lib'
  sys.executable = '/Users/gianluca/miniconda3/bin/python'
  sys.prefix = '/Applications/Spyder.app/Contents/Resources'
  sys.exec_prefix = '/Applications/Spyder.app/Contents/Resources'
  sys.path = [

    '/Applications/Spyder.app/Contents/Resources/lib/python3.11',
    '/Applications/Spyder.app/Contents/Resources/lib/python3.11/lib-dynload',
  ]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding

我还尝试直接从我的 MAC 终端安装模块（pip install quandl），一切都很好，但我认为我已经在不同的 python 解释器上安装了该模块，因为如果我尝试在 Spyder 上导入模块，它不起作用。我还尝试更改 Spyder 上的解释器，但我在 iPhyton 控制台上收到此消息

An error ocurred while starting the kernel
The Python environment or installation whose interpreter is located at
    /Users/gianluca/miniconda3/bin/python
doesn't have the spyder‑kernels module or the right version of it installed (>= 2.5.0 and < 2.6.0). Without this module is not possible for Spyder to create a console for you.

You can install it by activating your environment first (if necessary) and then running in a system terminal:
    conda install spyder-kernels=2.5
or
    pip install spyder-kernels==2.5.*

所以我尝试在终端上运行命令 conda install spinder-kernels=2.5 但我看到了这条消息

Retrieving notices: ...working... done

有人知道我必须做什么才能最终在我的 Spyder 上安装该模块吗？ 谢谢你帮助我:)

我认为你想要做的就是在 Anaconda 环境中安装

quandl

。

就上下文而言，您不会“在 Spyder 中”安装 Python 包； Spyder 是一个用 Python 编写的 IDE，是 Anaconda Python 分发环境的核心。要完成大多数事情，您需要安装带有spyder、numpy、matplotlib 等的Python...这些都是不同的Python 包。 Anaconda 只是为那些在必须构建/编译某些东西时不想在终端/控制台中进行修改的人提供了一个分发和包管理系统。

您可以在此处找到有关安装软件包的说明： https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/installing-with-conda.html

conda

是 Anaconda 的“包管理器”。您想要做的是尝试启动 Anaconda 控制台，您将处于包含 Spyder 包（和其他 Python 包）的环境中并执行

conda install quandl

命令。

请注意，您可能需要启用具有

quandl

包的不同 Anaconda 存储库（如 conda-forge）。
