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。
再加上乔杜里的回答:
在我的情况下,我得到了另一个关于lxml的错误如下:
copying src\lxml\isoschematron\resources\xsl\iso-schematron-xslt1\readme.txt -> build\lib.win-amd64-3.7\lxml\isoschematron\resources\xsl\iso-schematron-xslt1
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
我必须安装lxml - 4.2.3 - cp37 - cp37m - win_amd64。与Sushant Chaudhary的回答一样,成功完成Scrapy的安装。
下载lxml 4.2.3——cp37 cp37m——win_amd64。whl来自Lxml
把它放在Python安装的文件夹里
使用PIP Install <file-name>安装它
现在您可以运行pip install scrapy。
首先,你需要从https://visualstudio.microsoft.com/downloads#other下载visualstudio构建工具
重命名文件vs_buildtools.exe(不是必需的,但您必须修改下面的脚本)
start-process -wait -filepath vs_buildtools.exe -ArgumentList '--quiet --wait --norestart --nocache --installPath C:\BuildTools `
--add Microsoft.VisualStudio.ComponentGroup.VC.Tools.142.x86.x64 `
--add Microsoft.VisualStudio.Component.Windows10SDK.19041 `
--add Microsoft.VisualStudio.Component.Windows10SDK `
--add Microsoft.VisualStudio.Component.VC.CoreIde `
--add Microsoft.VisualStudio.Component.VC.CMake.Project `
--add Microsoft.VisualStudio.Component.VC.14.29.16.11.CLI.Support `
--add Microsoft.VisualStudio.ComponentGroup.UWP.VC.v142'
我在这里为windows docker用户创建了一个单独的问题和答案,Microsoft Visual c++ 14.0是必需的,在windows docker上安装pip包
要解决以下任何错误:
misaka的车轮建造失败
建造misaka失败
需要Microsoft Visual c++ 14.0
无法找到vcvarsall.bat
解决方案是:
Go to Build Tools for Visual Studio 2017
Select free download under Visual Studio Community 2017. This will download the installer. Run the installer.
Select what you need under workload tab:
a. Under Windows, there are three choices. Only check Desktop development with C++.
b. Under Web & Cloud, there are seven choices. Only check Python development (I believe this is optional, but I have done it).
In cmd, type pip3 install misaka.
Note if you already installed Visual Studio then when you run the installer, you can modify yours (click modify button under Visual Studio Community 2017) and do steps 3 and 4.
Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient. (You can also install the Visual Studio Build Tools with only these options, so you don’t need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5 GB, so saving off anything is helpful
