安装PIP3安装quandl - 返回失败清洗建立加密

Question

DIR我有以下配置

• 的Ubuntu LTS 16.04
• 的Python 3.5
• PIP 8.1.1。
• CFFI 1.8.3
• IDE PyCharm 2.3（并不重要，但以防万一）

我检查了文章Python的加密封装的PIP和setup.py - Failed to install Python Cryptography package with PIP and setup.py。似乎什么都没有解决。

我模块的最新版本（setuptools的等）

似乎正在努力建立一个构造函数和发现一些不匹配的版本

  File "/tmp/pip-build-nrsep1ln/cryptography/src/_cffi_src/utils.py", line 69, in build_ffi 
     ffi = FFI() 
    File "/home/alex/.local/lib/python3.5/site-packages/cffi/api.py", line 59, in __init__ 
     "version mismatch, %s != %s" % (backend.__version__, __version__) 
    AssertionError: version mismatch, 1.5.2 != 1.8.3 

     MY SYSTEM HAS 1.8.3 VERSION SEE BELOW

Answer 1

我在Raspberry Pi上运行python（linux也是如此）。

经过一番研究，我发现可能没有安装正确的库，然后安装quandl，最有可能的是ssl。熊猫和sklearn也许是必要的（当然熊猫）。

sudo apt-get install libssl-dev 

pip install pandas 

pip install sklearn 

如果在此之后它仍然不起作用，请尝试安装ffi。在所有其他的东西之后，这是为我工作的那个。

sudo apt-get install libffi-dev 

这是什么使它正确地做轮密码学和ciffi的东西。

使用Pip3命令可能适用于某些人，但并未改变我没有安装正确工具的事实。希望这对你有用。

P.S.我也认为它必须与我一起使用虚拟环境或quandl存储库，但这些似乎完全与错误无关，因为它实际上正在尝试安装，但只是缺少所需的工具。
