我已经安装了Python 3.5并且在运行时

pip install mysql-python

它给了我以下错误

error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)

我在路径中添加了以下行

C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;

C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC

我的PC上有64位win 7设置.

什么是解决此错误和正确安装模块的解决方案pip.

安装Visual Studio 2015并在以前的项目上运行CMake后,CMake错误表明它无法找到C编译器.

The C compiler identification is unknown
The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:4 (PROJECT):
  No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:4 (PROJECT):
  No CMAKE_CXX_COMPILER could be found.

我cl.exe在Visual Studio文件夹中搜索,C:\Program Files\Microsoft Visual Studio 14.0但找不到它.

如何使用Visual Studio 2015将CMake设置为在Windows上运行？

我刚刚安装了Windows 10 Creators Update(版本10.0.15063).

我安装了多个版本的Visual Studio(2012年,2013年,2015年和2017年).我几周前才安装了VS 2017.

问题

在"VS2015 x64本机命令提示符"中运行时,CMake(版本3.8.1)不再找到C/C++编译器(在VS 2017命令提示符下运行时它可以正常工作).

再生产

内容CMakeLists.txt:

project (test)
add_executable (test test.cpp)

(内容test.cpp无关紧要.)

在VS2015 x64本机命令提示符中进行CMake调用:

> mkdir build
> cd build
> cmake -G "Visual Studio 14 2015 Win64" ..

CMake输出:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:1 (project):
  No CMAKE_C_COMPILER could be found.

pip install pycrypto 使用python3.5.2可以正常工作,但是由于python3.6而失败并出现以下错误:

inttypes.h(26):错误C2061:语法错误:标识符'intmax_t'

我有一个全新的Python 3.6 + Selenium安装,现在想安装Clarifai 2.0.21.

以下命令失败:

python -m pip install clarifai==2.0.21

起初它要求VC++ 14.0,但我有14.1(VS2017),所以我安装了VC++ 2015 BuildTools,它有14.0.这部分工作直到创建库.

我接下来得到了新的错误:

生成代码
完成生成代码
LINK:致命错误LNK1158:无法运行'rc.exe'错误:命令'C:\ Program Files(x86)\ Microsoft Visual Studio 14.0\VC\BIN\link.exe'失败,退出状态为1158

不知道我的装置中是否缺少某些东西？谢谢

我刚刚运行了"pip install -U steem"命令,安装工作正常,直到它无法安装pycrypto.之后我做了"pip install cryptography"命令,因为我认为它是缺少的包.所以我的问题是,如何在没有pycrypto-error(或者另外还有pycrypto-package)的情况下安装steem,以及如何卸载我不需要的cryptography-Package.(我使用的是Windows 7和Python 3)

我想在运行以下命令时在 Windows 系统中安装协议缓冲区：

cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../../../../install ../..

我已经使用离线安装程序安装了Qt qt-opensource-windows-x86-msvc2015_64-5.8.0.我有使用c ++构建工具安装的visual studio社区版2017.因为它的编译器与qt版本不兼容,所以我从http://landinghub.visualstudio.com/visual-cpp-build-tools安装了visual c ++ build tools 2015.当我尝试编译项目时,它会出错.这是我的qt工具包的样子, :-1: error: LNK1158: cannot run 'rc.exe'

有人可以弄清楚这是什么错误以及如何解决它.谢谢.
