错误:无法找到vcvarsall.bat

我正在尝试为python安装MySql接口,但是我收到了一个错误(如下所述).我知道解决方案:安装Microsoft Visual C++.除了安装Microsoft Visual C++之外,还有其他解决方案吗？我的意思是这真的伤害了我; 我为什么要安装Microsoft Visual C++只是因为构建这个单独的包,从开发人员的角度来看,这是一种无用且浪费时间的方法.这个问题还有其他解决方案吗？

error: Unable to find vcvarsall.bat

我在Windows XP上使用Python 2.6.

我试图在Windows 10下使用Visual Studio 2015终极安装在python 3.5中安装numpy.

短版本:vcvarsall.batvs14文件C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC夹文件夹中缺少文件.为什么？

长版:跑步pip install numpy给我这个错误error: Unable to find vcvarsall.bat

研究这个错误让我得到了几个stackoverflow答案,帮助我弄清楚python需要c ++编译器来编译一些包.并且它需要使用用于编译python 3.5的相同版本的编译器来执行此操作( 错误:无法找到vcvarsall.bat).我的python是使用[MSC v.1900 64位(AMD64)]编译的 - 这是vs 14(visual studio 2015)

与我的研究,我从中学到了进一步的运动: PIP安装提示错误:无法找到vcvarsall.bat是 get_build_version()从$python_install_prefix/Lib/distutils/msvc9compiler.py回报的VS是768,16可以用来寻找路径的版本,vcvarsall.bat 对于我这个方法返回14,所以一切都正确.

现在,当我查看文件夹时C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC,文件vcvarsall.bat丢失了.

但是当我查看文件夹时,C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC有一个vcvarsall.bat.

为什么vs 14.0中缺少vcvarsall.bat？

问题:如何解决错误？跑步pip install zipline[all]给出了同样的错误......

我已经安装了MSVC++ 2010 Express,而我的vcvarsall.bat文件C:\Program Files\Microsoft Visual Studio 10.0\VC位于我的系统PATH中.当我运行时easy_install,它找不到vcvarsall.bat.

我需要在distutils.cfg文件中设置一些东西来指向我的MSVC++安装吗？

我已经在python中创建了一个字典并将其转换为pickle.它的大小达到了300MB.现在,我想加载相同的泡菜.

output = open('myfile.pkl', 'rb')
mydict = pickle.load(output)

加载这个泡菜大约需要15秒.我怎样才能减少这个时间？

硬件规格:Ubuntu 14.04,4GB RAM

下面的代码显示了使用json,pickle,cPickle转储或加载文件所需的时间.

转储后,文件大小约为300MB.

import json, pickle, cPickle
import os, timeit
import json

mydict= {all values to be added}

def dump_json():    
    output = open('myfile1.json', 'wb')
    json.dump(mydict, output)
    output.close()    

def dump_pickle():    
    output = open('myfile2.pkl', 'wb')
    pickle.dump(mydict, output,protocol=cPickle.HIGHEST_PROTOCOL)
    output.close()

def dump_cpickle():    
    output = open('myfile3.pkl', 'wb')
    cPickle.dump(mydict, output,protocol=cPickle.HIGHEST_PROTOCOL)
    output.close()

我已经安装了Microsoft Visual Studio 2008.我下载了用于Windows扩展的zip文件Python,并将内容解压缩到我的Python27文件夹中.现在有一个名为pywin32-214的子文件夹.(32部分是一个问题吗？我在64位系统上.)这是命令行的成绩单:

我一直在尝试在我的Window 7系统上安装Cython for Python 2.7.特别是,我更喜欢64位的所有内容.(如果你想知道,我需要Cython,因为Cython是我需要另一个软件包进行专门的数值分析所需的组件之一.而x64可能是存储大型数据集的一个优势.)

所以我从官方网站下载了x64 Python 2.7.来自Christoph Gohlke的Cython.当然,Python 2.7的amd64版本.在我安装之前,我将Python 2.7添加到注册表中,其中.reg包含Joe DF的答案中的文件.之后,我从这里安装了Visual C++编译器(我认为它不起作用)和这里(但是应该这样).在这一点上,我有我的C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin目录中所有的vcvars32.bat,vcvars64.bat,vcvars86_amd64.bat,vcvarsx86_ia64.bat.我跑了vcvars64.bat,没有错误信息.

随后,我按照此页面创建了一个"hello world"测试文件.

然后,我收到了这个错误.

...\Tests>python setup.py build_ext --inplace
running build_ext
building 'hello' extension
error: Unable to find vcvarsall.bat

所以我心想:嗯,Cython找不到那个文件,因为它不存在.(我搜索我的整个它的硬盘.)所以我复制vcvars64.bat从...\VC\bin到\VC,改变了名称vcvarsall.bat.现在vcvarsall错误消失了.而且......自然会出现一个新的错误.

我正在尝试编写一些使用Numpy的代码.但是,我无法导入它:

Python 2.6.2 (r262, May 15 2009, 10:22:27) 
[GCC 3.4.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

我尝试了这个问题中的建议:

>>> import sys
>>> print sys.path
['', '/usr/intel/pkgs/python/2.6.2/lib/python26.zip', '/usr/intel/pkgs/python/2.6.2/lib/python2.6', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/plat-linux2', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-tk', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-old', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-dynload', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/site-packages']

我搜索了numpy该路径中命名的文件:

$ find /usr/intel/pkgs/python/2.6.2/bin/python -iname numpy\*

但没有出现.

所以...

• 是否还有其他通常安装Python模块的地方？
• 如果事实证明它没有安装在中心区域,我如何在我的帐户中本地安装numpy？

我无法通过pip install numpy在运行Python 3.4的计算机上安装numpy,因为我收到的各种错误都与编译问题有关(这只是64位Python安装的情况).

这是一个已被广泛报道的问题,我有一个关于无法找到vcvarsall.bat 的相关问题.我已经在运行Windows 8.1,7企业版和7家庭版的三台不同的清洁机器上进行了测试,它总是出现.

安装Visual Studio 2010 Express C++摆脱了链接中的第一个错误 - 即无法找到vcvarsall.bat但抛出以ValueError结尾的下一个异常,如下所示:

  File "C:\Python34\lib\distutils\msvc9compiler.py", line 371, in initialize

    vc_env = query_vcvarsall(VERSION, plat_spec)

  File "C:\Python34\lib\distutils\msvc9compiler.py", line 287, in query_vcvarsall

    raise ValueError(str(list(result.keys())))

ValueError: ['path']

然后我按照这个建议修改了在讨论论坛中链接的文件,导致了KEY_BASE错误.
