First of all, install virtualenvinside your project folder to secure your project directory to avoid conflict with your other packages.

首先，安装virtualenv在您的项目文件夹中以保护您的项目目录，以避免与其他软件包发生冲突。

pip install virtualenv

After installing this run this command one by one inside your root project directory:

安装完这个后，在你的项目根目录中一一运行这个命令：

virtualenv venv
source venv/bin/activate

Now Your directory is secure and you can install your required packages inside.

现在你的目录是安全的，你可以在里面安装你需要的包。

pip install pandas

and others as you required.

和其他你需要的。

Because you have installed virtualenvand running as secure it will not conflict with other outside packages.

因为您已经virtualenv安全地安装和运行，所以它不会与其他外部软件包发生冲突。

Use this all steps one by one. I hope it will work for you to avoid such error.

一步一步地使用所有步骤。我希望它对您有用，可以避免此类错误。

Thanks.

谢谢。

I had Python2and Python3installed in different directories but I was facing this error because whenI was using the command pip install pandasit was installing pandas in Python2directories while I was using Python3

我已经Python2并Python3安装在不同的目录中，但是我遇到了这个错误，因为当我使用该命令时，pip install pandas它正在Python2目录中安装pandas，而我正在使用Python3

So I had two diectories with Python2 --> C:\Python27and Python365 --> C:\Python365.

所以我有两个带有Python2 --> C:\Python27和的字典Python365 --> C:\Python365。

To resolve this error:

要解决此错误：

Run pip install pandasin cmd. If library pandasis already installed you'll see something like following.

运行pip install pandas在cmd。如果库pandas已安装，您将看到如下内容。

C:\Users\vichitrak>pip install pandas
Requirement already satisfied: pandas in c:\python27\lib\site-packages (0.23.4)
Requirement already satisfied: python-dateutil>=2.5.0 in c:\python27\lib\site-packages (from pandas) (2.7.3)
Requirement already satisfied: numpy>=1.9.0 in c:\python27\lib\site-packages (from pandas) (1.14.4)
Requirement already satisfied: pytz>=2011k in c:\python27\lib\site-packages (from pandas) (2018.4)
Requirement already satisfied: six>=1.5 in c:\python27\lib\site-packages (from python-dateutil>=2.5.0->pandas) (1.11.0)

From the output of above command you can see that pandasis installed in Python2directory i.e. c:\python27\lib\site-packages (0.23.4)

从上面命令的输出中你可以看到它pandas安装在Python2目录 iec:\python27\lib\site-packages (0.23.4)

Run pythoncommand in cmdto check which Pythonversion are you running.

运行python命令cmd以检查Python您正在运行的版本。

C:\Users\vichitrak>python

To install the pandasand other libraries in Python3go to scripts folderin Python3 directory i.e. C:\Python365\Scripts
Open Command Windowand run pip install pandas

要安装pandas在和其他图书馆Python3转到scripts folder在Python3 directory i.e. C:\Python365\Scripts
打开Command Window和运行pip install pandas

Or you can use the complete path of pip in Python3 directoryon cmdto run the intsallcommand i.e. C:\Users\vichitrak>C:\Python365\Scripts\pip install pandas

或者你可以使用complete path of pip in Python3 directoryoncmd来运行intsall命令即C:\Users\vichitrak>C:\Python365\Scripts\pip install pandas

Sometimes, it might be due to an issue with "Microsoft visual C++".

有时，这可能是由于“Microsoft Visual C++”的问题。

1. For that, first you need to install the "Microsoft visual C++" using the instructions given in the link: "[Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)"
2. After successful installation, use pip install pandasto install pandas
3. If pipis not installed, then download thr pandas source package with extension tar.gzand place it in directory wherever you want after extracting. open cmd.exeand navigate to the path where pandas folder is extracted & placed using cd C:/pandas. Then install it using the python setup.py install

1. 为此，首先您需要使用链接中给出的说明安装“Microsoft Visual C++”：“[需要Microsoft Visual C++ 14.0（无法找到 vcvarsall.bat）”
2. 安装成功后，使用pip install pandas安装pandas
3. 如果pip未安装，则下载带有扩展名的 thr pandas 源包，tar.gz并在解压缩后将其放在您想要的目录中。打开cmd.exe并导航到使用 .pandas 文件夹提取和放置的路径cd C:/pandas。然后使用安装python setup.py install

Finally you should get the success message as Finished processing dependencies for pandas==0.xx.0

最后你应该得到成功消息 Finished processing dependencies for pandas==0.xx.0
