Question

我刚刚运行了＆＃34; pip install -U steem＆＃34; -command，安装运行良好，直到它无法安装pycrypto。之后我做了＃34; pip install cryptography＆＃34;命令，因为我认为这是缺少的包。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加密包。（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。使用指向Visual C++ 2015 Build Tools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pycrypto的方法，这些方法不需要安装编译器。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。保证您获得与您的Python版本兼容且未使用任何后门构建的pycrypto版本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

-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.

如果您尚未安装steem库，则可以在不使用-U选项的情况下运行该命令。

Answer 2

作为安装Visual C ++的替代方法，有一种方法可以在Conda中安装其他软件包（此选项不需要管理员权限）。这对我有用：

conda install libpython m2w64-toolchain -c msys2

Answer 3

我尝试安装pymssql时出现此错误，即使我的系统中安装了Visual C ++ 2015（14.0）。

我通过从new BigDecimal(String val)

下载pymssql的.whl文件解决了这个错误

下载后，可以通过以下命令安装：

pip install python_package.whl

希望这有帮助

Answer 4

在Windows上，我强烈建议您安装最新的Visual Stuido Community，它是免费的，如果仅安装vc_redist，您可能会错过一些构建工具，因此您可以通过pip轻松安装软件包wheel中，可以节省大量时间

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。

要这样做：

打开Visual Studio安装程序（如果需要，可以在“开始”菜单中搜索它）。
找到Visual Studio生成工具，然后单击“修改”：

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：

在C ++工具完成安装后，再次运行pip命令，它应该可以工作。

Answer 6

Pycrypto的漏洞已分配了CVE-2013-7459号，并且自June 23, 2014以来，该存储库不接受PR。

Pycryptodome是PyCrypto库的直接替代品，该库提供了与旧PyCrypto几乎相同的API，请参见Compatibility with PyCrypto。

如果尚未安装pycrypto，则可以使用pip install pycryptodome来安装pycryptodome，而不会出现Microsoft Visual C ++ 14.0问题。

Answer 7

在搜索“需要Microsoft Visual C ++ 14.0。使用“ Microsoft Visual C ++生成工具” 来获得它之后，我着陆了这个问题。尝试运行{{ 1}}从具有C ++扩展名的源代码发行版本构建自己的Python包。最后，我要做的就是在调用pip install之前升级setuptools：

pip install

因此，有关从源归档文件进行安装时更新pip install --upgrade setuptools的建议here完全正确：）。该建议也提供了here。

Answer 8

我遇到了同样的问题。在这里找到修复程序。 https://github.com/statsmodels/statsmodels/issues/4160

基本上就是安装

http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe

shasum输出：

3e0de8af516c15547602977db939d8c2e44fcc0b visualcppbuildtools_full.exe md5sum输出：

MD5（visualcppbuildtools_full.exe）= 8d4afd3b226babecaa4effb10d69eb2e

再次运行您的pip安装命令。如果一切正常，那就很好。否则您可能会像我一样遇到以下错误：

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

在此处找到针对上述问题的解决方案： Visual Studio can't build due to rc.exe

这基本上是

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

它就像一种魅力

Answer 9

尝试这样做：

py -m pip install pipwin
py -m pipwin install PyAudio

Answer 10

此处更新了 Microsoft Visual C++ 14.0 下载链接

Download

它适用于没有 Visual Studio 下载器的我

Answer 11

让我们一劳永逸地解决这个问题（仅限 Anaconda 设置），尝试：

<块引用>

conda install -c conda-forge 隐式

Pip错误：需要Microsoft Visual C ++ 14.0
