I have tried all suggestions and found my own simple solution.
我已经尝试了所有建议并找到了我自己的简单解决方案。
The problem is that codes written in external environment like Cneed compiler. Look for its own VS environment, i.e. VS 2008.
问题是在外部环境中编写的代码C需要编译器。寻找自己的VS环境，即VS 2008。
Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat.
I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLSas variable name and gave the value of VS120COMNTOOLS.
目前我的机器运行 VS 2012 并面对Unable to find vcvarsall.bat. 我研究了要安装的代码以找到 VS 版本。那是 VS 2008。我已将系统变量添加VS90COMNTOOLS为变量名并给出了VS120COMNTOOLS.
You can find my step by step solution below:
您可以在下面找到我的分步解决方案：
- Right click on My Computer.
- Click Properties
- Advanced system settings
- Environment variables
- Add New system variable
- Enter VS90COMNTOOLS to the variable name
- Enter the value of current version to the new variable.
- Close all windows
- 右键单击我的电脑。
- 单击属性
- 高级系统设置
- 环境变量
- 添加新的系统变量

Try installing this, it's a known workaround for enabling the C++ compiler for Python 2.7.
尝试安装它，这是为 Python 2.7 启用 C++ 编译器的已知解决方法。
In my experience, when pip does not find vcvarsall.bat compiler, all I do is opening a Visual Studio console as it set the path variables to call vcvarsall.bat directly and then I run pip on this command line.
根据我的经验，当 pip 找不到 vcvarsall.bat 编译器时，我所做的就是打开 Visual Studio 控制台，因为它设置了路径变量以直接调用 vcvarsall.bat，然后我在此命令行上运行 pip。

Here too I can reproduce this problem with scrapyand psycopg2(both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7installed.
即使我安装了适用于 Python 2.7 的 Microsoft Visual C++ 编译器，我也可以使用scrapy和psycopg2（都需要 C++ 编译）来重现这个问题。
It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.
必须指出的是，我使用virtualenv. 从您的帖子中，我不确定您是否也这样做。
Anyway I tried to skip the activation of the virtual environment. Then both scrapyand psycopg2installed fine.
无论如何，我试图跳过虚拟环境的激活。然后，两个scrapy和psycopg2安装罚款。
My hypothesis: there is a conflict between this 2014 C++ compiler for Pythonand virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).
我的假设：这个 2014 C++ 编译器的 Python和 virtualenv之间存在冲突。我不知道为什么也不知道如何解决它（如果有人可以提出解决方法，我会很高兴）。

I was getting the same error in python 3.4.3 too and I tried using the solutions mentioned here and elsewhere with no success.
我在 python 3.4.3 中也遇到了同样的错误，我尝试使用这里和其他地方提到的解决方案，但没有成功。
Microsoft makes a compiler available for Python 2.7 but it didn't do me much good since I am on 3.4.3.
Microsoft 为 Python 2.7 提供了一个编译器，但由于我使用的是 3.4.3，它对我没有多大好处。

Because previous versions gave a different error for vcvarsall.bat I would double check the version you are using with "pip -V"
因为以前的版本为 vcvarsall.bat 给出了不同的错误，我会用“pip -V”仔细检查您使用的版本
C:\Users\B>pip -V
pip 6.0.8 from C:\Python34\lib\site-packages (python 3.4)
As a side note, I too tried using the latest version of VC++ (2013) first but it required installing 2010 express.
作为旁注，我也尝试首先使用最新版本的 VC++（2013），但它需要安装 2010 express。
From that point forward it should work for anyone using the 32 bit version, if you are on the 64 bit version you will then get the ValueError: ['path'] message because VC++ 2010 doesn't have a 64 bit compuler. For that you have to get the Microsoft SDK 7.1. I can't hyperlink the instruction for 64 bit because I am limited to 2 links per post but its at
从那时起，它应该适用于使用 32 位版本的任何人，如果您使用的是 64 位版本，那么您将收到 ValueError: ['path'] 消息，因为 VC++ 2010 没有 64 位编译器。为此，您必须获得 Microsoft SDK 7.1。我无法超链接 64 位指令，因为我每个帖子只能有 2 个链接，但它位于

After doing a lot of things, I upgraded pip, setuptoolsand virtualenv.
在做了很多事情之后，我升级了pip,setuptools和virtualenv.
python -m pip install -U pippip install -U setuptoolspip install -U virtualenv

I did steps 1, 2 in my virtual environment as well as globally.
Next, I installed the package through pipand it worked.
我在我的虚拟环境以及全局环境中执行了步骤 1、2。接下来，我安装了该软件包pip并且它起作用了。
