如何解决我无法在Windows 10 64位上使用带有pip的Python 3.9.0 64位安装任何软件包
我无法安装任何软件包。我什至尝试更新pip和setuptools。 我尝试多次卸载并重新安装python,但仍然是相同的错误。 我之前有python 3.8(32位),当时工作正常。但是,我需要使用64位的tensorflow,因此我卸载了拥有最新(3.9)64位版本的版本。我的Windows是64位的,所以没有问题。 我收到的错误,

解决方法
我无法安装任何软件包。
否,如果您阅读了错误消息,则无法安装需要编译的软件包(因为它们包含本机代码)。我可以肯定,某些纯Python软件包可以正常运行
。在Windows上,由于大多数系统都没有构建工具,因此本机软件包通常以预构建的二进制文件(“二进制文件”)的形式提供。
不过,尽管纯Python包通常是多版本的,但需要为每个单独的Python版本分别构建和分发二进制轮子。
由于Python 3.9是最新版本(已经2周了),因此可以认为,软件包的维护者可能还没有时间和机会对其各自的软件包进行问答,因此尚未构建相应的软件包。分发轮。
您的解决方案因此是:
-
处于边缘并且错误消息告诉您
错误:需要Microsoft Visual C ++ 14.0。通过“ Visual Studio的构建工具”获得它:https://visualstudio.microsoft.com/downloads/
通过安装MSVC ++,您将能够(尝试)在本地编译二进制程序包,这可能会成功也可能不会成功,因为这些程序包可能与3.9本身不兼容
-
更安全地生活,删除3.9并安装3.8,为此您想要的包装可能带有轮子
-
等到您要发布3.9的二进制文件的软件包
-
安装“科学分发版”,通常可以处理整个事情,例如水蟒
