Pip错误:需要Microsoft Visual C++ 14.0

Question

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)

Answer 1

您需要安装Microsoft Visual C++ 14.0才能安装pycrypto:

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

在评论中,您询问使用哪个链接.使用Visual C++ 2015构建工具的链接.这将安装Visual C++ 14.0而无需安装Visual Studio.

在评论中,您询问安装方法,pycrypto不需要安装编译器.链接中的二进制文件似乎是用于早期版本的Python而不是您使用的.一个链接是DropBox帐户中的二进制文件.

我不建议下载第三方提供的二进制版本的加密库.保证您获得的版本pycrypto与您的Python版本兼容且没有使用任何后门构建的唯一方法是从源代码构建它.

安装Visual C++后,只需重新运行原始命令:

pip install -U steem

要了解各种安装选项的含义,请运行以下命令:

pip help install

该-U选项的帮助说

-U, --upgrade        Upgrade all specified packages to the newest available
                     version. The handling of dependencies depends on the
                     upgrade-strategy used.

如果尚未steem安装库,则可以在不使用该-U选项的情况下运行该命令.

Answer 2

在搜索“Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools" 后，我找到了这个问题。尝试pip install从具有C++ 扩展。最后我所要做的就是setuptools在调用之前升级pip install：

pip install --upgrade setuptools

所以这里关于setuptools从源存档安装时更新的建议毕竟是正确的:)。这里也给出了这个建议。

Answer 3

作为安装 Visual C++ 的替代方法，有一种方法是在 Conda 中安装附加包（此选项不需要管理员权限）。这对我有用：

conda install libpython m2w64-toolchain -c msys2

Answer 4

我遇到了同样的问题。在这里找到了修复程序。

基本上只需安装这个。

shasum 输出：

3e0de8af516c15547602977db939d8c2e44fcc0b  visualcppbuildtools_full.exe

md5sum 输出：

MD5 (visualcppbuildtools_full.exe) = 8d4afd3b226babecaa4effb10d69eb2e

再次运行 pip 安装命令。如果一切正常，那就太好了。或者你可能会像我一样面临以下错误：

Finished generating code
    LINK : fatal error LNK1158: cannot run 'rc.exe'
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158

在此处找到上述问题的修复程序： Visual Studio can't build due to rc.exe

那基本上说

Add this to your PATH environment variables:

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

Copy these files:

rc.exe
rcdll.dll

From

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

To

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin

它就像一个魅力

Answer 5

如果已经安装了Visual Studio Build Tools，但仍然出现该错误，则可能需要“修改”安装以包括Visual C ++生成工具。

要做到这一点：

1. 打开Visual Studio安装程序（如果需要，可以在“开始”菜单中搜索它）。

2. 找到Visual Studio构建工具，然后单击“修改”：

3. 在Visual C ++生成工具中添加一个选中标记，然后单击右下角的“修改”以安装它们：

C ++工具完成安装后，再次运行pip命令，它应该可以工作。

Answer 6

此处更新了下载 Microsoft Visual C++ 14.0 的链接

• 下载

它适合我，无需 Visual Studio 下载器

Answer 7

即使我的系统中安装了Visual C ++ 2015（14.0），当我尝试安装pymssql时也遇到此错误。

我通过从https://www.lfd.uci.edu/~gohlke/pythonlibs/下载pymssql的.whl文件解决了此错误。

下载后，可以通过以下命令进行安装：

pip install python_package.whl

希望这可以帮助

Answer 8

Pycrypto 存在编号为CVE-2013-7459 的漏洞，并且该存储库自2014 年 6 月 23 日起不再接受 PR 。

Pycryptodome是 PyCrypto 库的直接替代品，它公开了与旧 PyCrypto 几乎相同的 API，请参阅 与 PyCrypto 的兼容性。

如果您还没有安装 pycrypto，您可以使用pip install pycryptodomepycryptodome 安装，这样就不会出现 Microsoft Visual C++ 14.0 问题。
