ImportError：没有名为pandas的模块

75

我正在尝试在python中编写代码以获取Twitter数据，但twython并没有收到错误。但是我对熊猫错误。

我已经使用pip install pandas安装了pandas。但是我仍然会收到这个错误。请帮忙

您的熊猫安装失败。与其手动自己安装（它有很多依赖项，需要编译Python的本机扩展），不如手动安装它，我建议您使用Anaconda Python发行版continuum.io/downloads
— Bernhard
附带说明一下，在Visual Studio Code中使用ps终端安装熊猫时，会出现奇怪的错误。在cmd中似乎有效。

您缺少一些步骤（不是很清楚）。熊猫通过点子作为轮子分布，这意味着您需要执行以下操作：

pip install wheel
pip install pandas

在此之后，您可能会遇到其他问题-好像您正在Windows上安装，这不是numpy / scipy / pandas的最友好目标。或者，您可以从此处获取二进制安装程序。

您还安装numpy时出错。和以前一样，我建议为此安装一个二进制安装程序，因为这不是一个简单的过程。但是，您可以通过从Microsoft安装此软件包来解决当前的错误。

尽管可以在Windows上获得完美的环境设置是完全有可能的，但我发现通过设置debian VM可以大大改善Python开发人员的生活质量。尤其是在使用科学软件包的情况下，您会遇到许多类似情况。

回答这个问题可能为时已晚，但我遇到了问题，并且一直安装和卸载，事实证明，当您安装pandas到的版本python并尝试使用其他版本运行程序时，会发生问题python version

因此，开始运行： 

which python
python --version
which pip

确保两个排列，最有可能的，Python2.7和PIP正在3.x或点子是从水蟒的蟒版本，这是极有可能成为未来3.x以及

如果python重定向到2.7，并且pip重定向到pip3，请使用安装pandaspip install pandas并用于python3 file_name.py运行程序。

我使用以下命令解决了相同的问题...在终端上键入python。如果看到python 2.x版本，请运行以下两个命令来安装pandas：

sudo python -m pip install wheel

和

sudo python -m pip install pandas

否则，如果您看到python 3.x版本，请运行以下两个命令来安装pandas：

sudo python3 -m pip install wheel

和

sudo python3 -m pip install pandas

祝好运！

如果您正在运行python版本3.9，pandas将无法正常工作。因此，请安装python 3.7或更低版​​本以缓解此问题。否则，如果您想使用python 3.9，请尝试通过编译库来安装pandas

截至2020年12月，python v 3.8.6通过安装时我遇到了同样的问题pyenv。因此，我开始于：

  1. 通过自制软件安装pyenv brew install pyenv
  2. 通过安装xz编译软件包 brew install xz
  3. pyenv install 3.8.6 选择所需的版本
  4. pyenv global 3.8.6 将此版本设为全局
  5. python -m pip install -U pip 升级点
  6. pip install virtualenv

在那之后，我初始化了我的新环境，pandas通过pip命令安装了它，一切又恢复了。我的工作项目目录中已安装熊猫的版本为1.1.5。希望对您有所帮助！

注意：如果您在xz之前安装了python，请确保先将其卸载，否则错误可能仍然存在。

对我来说它是如何工作的，我有两个可执行版本的python，所以在pip install上它安装在一个版本中，但是我的可执行文件路径版本不同，因此失败了，然后我更改了sys环境变量中的路径并安装了可执行文件版本python，它能够从site-packages识别包
