我已经安装了Python 3.5,并且正在运行
pip install mysql-python
它给出了如下错误
错误:Microsoft Visual c++ 14.0是必需的(无法找到vcvarsall.bat)
我已经添加了以下行到我的路径
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
我的电脑上安装了64位的Windows 7。
什么解决方案可以减少这个错误,并通过pip正确安装模块。
我在安装mayavi时遇到了这个问题。
我还犯了一个常见错误:在pip安装库时需要Microsoft Visual c++ 14.0。
在浏览了许多网页和这个问题的解决方案后,没有一个可行,我想出了这些步骤(大部分取自以前的解决方案)可以让这个问题起作用。
Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) → Tools for Visual Studio 2017
If you have already installed this, skip to 2.
Select the C++ components you require (I didn't know which I required, so I installed many of them).
If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 → Modify → Individual Components and selected the required components.
From other answers, important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features.
Install/Modify these components for Visual Studio Build Tools 2017.
This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools → Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools.
Now enter python -m pip install --upgrade setuptools within this CMD window.
Finally, in this same CMD window, pip install your Python library: pip install -U <library>.
