Python anaconda - Windows 中的路径环境变量

anaconda - path environment variable in windows

提问by Alejandro Simkievich

I am trying to run python from the windows command prompt (windows 10). So the result is the typical one when the path environment variable is not configured

我正在尝试从 Windows 命令提示符（Windows 10）运行 python。所以结果就是没有配置path环境变量时的典型

 c:\windows\system32>python
'python' is not recognized as an internal or external command, operable
 program or batch file

however, I am not sure which is the right directory I should set up in the path variable.

但是，我不确定应该在路径变量中设置哪个目录是正确的。

I tried a few variations, and none of them work, including:

我尝试了一些变体，但都不起作用，包括：

c:\users\xxx\anaconda3
c:\users\xxx\anaconda3\Scripts
c:\users\xxx\anaconda3\libs\python34

and none of them works.

他们都没有工作。

Does anyone have experience with this particular system constellation (windows, anaconda). Thanks.

有没有人对这个特定的系统星座（windows，anaconda）有经验。谢谢。

it turns out I was mistaken.

原来我错了。

Solution is: in anaconda (as well as in other implementations), set the path environment variable to the directory where 'python.exe' is installed.

解决方案是：在anaconda（以及其他实现）中，将路径环境变量设置为安装“python.exe”的目录。

As a default, the python.exe file in anaconda is in:

默认情况下，anaconda 中的 python.exe 文件位于：

c:\.....\anaconda

after you do that, obviously, the python command works, in my case, yielding the following.

在你这样做之后，显然，python 命令在我的情况下工作，产生以下内容。

python
Python 3.4.3 |Anaconda 2.2.0. (64|bit)|(default, Nov 7 2015), etc, etc

C:\Users\<Username>\AppData\Local\Continuum\anaconda2

For me this was the default installation directory on Windows 7. Found it via Rusy's answer

对我来说，这是 Windows 7 上的默认安装目录。通过Rusy 的回答找到它

Instead of giving the path following way:

而不是以下列方式给出路径：

C:\Users\User_name\AppData\Local\Continuum\anaconda3\python.exe

Do this:

做这个：

C:\Users\User_name\AppData\Local\Continuum\anaconda3\

In windows 10 you can find it here:

在 Windows 10 中，您可以在这里找到它：

C:\Users\[USER]\AppData\Local\conda\conda\envs\[ENVIRONMENT]\python.exe

C:\Users\[USER]\AppData\Local\conda\conda\envs\[ENVIRONMENT]\python.exe

C:\Users\\Anaconda3

C:\用户\\Anaconda3

I just added above path , to my path environment variables and it worked. Now, all we have to do is to move to the .py script location directory, open the cmd with that location and run to see the output.

我刚刚将上面的 path , 添加到我的路径环境变量中并且它起作用了。现在，我们要做的就是移动到 .py 脚本位置目录，使用该位置打开 cmd 并运行以查看输出。

You could also just re-install Anaconda, and tick the option add variable to Path.. This will prevent you from making mistakes when editing environment variables. If you make mistakes here, your operating system could start malfunctioning.

您也可以重新安装 Anaconda，并勾选选项将变量添加到路径。这将防止您在编辑环境变量时出错。如果您在这里犯错，您的操作系统可能会开始出现故障。

The default location for python.exe should be here: c:\users\xxx\anaconda3One solution to find where it is, is to open the Anaconda Prompt then execute:

python.exe 的默认位置应该在这里：c:\users\xxx\anaconda3找到它所在位置的一种解决方案是打开 Anaconda Prompt 然后执行：

> where python

This will return the absolute path of locations of python eg:

这将返回 python 位置的绝对路径，例如：

(base) C:\>where python
C:\Users\Chad\Anaconda3\python.exe
C:\ProgramData\Miniconda2\python.exe
C:\dev\Python27\python.exe
C:\dev\Python34\python.exe

To export the exact set of paths used by Anaconda, use the command echo %PATH%in Anaconda Prompt. This is needed to avoid problems with certain libraries such as SSL.

要导出 Anaconda 使用的确切路径集，请使用echo %PATH%Anaconda Prompt 中的命令。这是避免某些库（如 SSL）出现问题所必需的。
