Question

我需要pycrypto，因为需要使用dnspython库中的某些函数。我在网上发现了一些帖子，表明pycrypto已经死了。但是，我需要dnspython并且别无选择，只能使用它。我甚至尝试安装pycryptodome，因为他们认为它是pycrypto的替代品，但我使用dnspython库的程序引发了错误：

Traceback (most recent call last):
  File "test-3-dnssec.py", line 40, in <module>
    dns.dnssec.validate(answer[0],answer[1],{name:answer[0]})
  File "C:\Python36\lib\site-packages\dns\dnssec.py", line 417, in _validate
    _validate_rrsig(rrset, rrsig, keys, origin, now)
  File "C:\Python36\lib\site-packages\dns\dnssec.py", line 371, in _validate_rrsig
    if pubkey.verify(digest, sig):
  File "C:\Python36\lib\site-packages\Crypto\PublicKey\RSA.py", line 372, in verify
    raise NotImplementedError("Use module Crypto.Signature.pkcs1_15 instead")
NotImplementedError: Use module Crypto.Signature.pkcs1_15 instead

根据similar error，使用pycryptodome代替pycrypto。在我的情况下，Pycryptodome不能代替pycrypto。

我安装了Visual Studio 2017.我按照库gihub page中的建议执行了这些步骤：

cd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build"
vcvarsall amd64
cd \
set CL=-FI"%VCINSTALLDIR%\tools\msvc\14.13.26128\include\stdint.h"

pip install pycrypto

不幸的是，这没有帮助。我甚至尝试从VC命令提示符运行pip install pycrypto但仍然无法安装它。我还在环境变量中添加了以下路径。

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build

安装尝试的摘要：

你能解决问题吗？

Answer 1

好的，我遇到了确切的问题，并且可以通过执行以下步骤来解决：

将Visual Studio VC目录添加到用户变量中的环境变量中：

Variable Name: VCINSTALLDIR
Variable Value: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC

请注意，变量应位于用户变量中，而不应位于系统变量中。

打开cmd后，键入以下命令。

set CL=/FI"%VCINSTALLDIR%\INCLUDE\stdint.h" %CL%

然后运行pip install

pip install pycrypto

在Windows 10 x64和Python 3.6.5中安装pycrypto：在C：\ Users \ x \ AppData \ Local \ Temp \ pip-install-u7xhxrk \ pycrypto \中失败，错误代码为1
