使用 pip 安装 Django-Fabric-AWS，语法无效？

【问题标题】：Installing Django-Fabric-AWS with pip, invalid syntax?使用 pip 安装 Django-Fabric-AWS，语法无效？

【问题描述】：

在 EC2 上部署 Django 的过程中，我正在遵循 this 指南中的一个步骤，该步骤要求我安装 Fabric。

在 Pycharm 的终端中，我首先通过运行pip 并在项目目录中确认 pip 正在工作。是的，所以我输入了我被指示的命令，pip install -r fabfile/requirements.txt，它会产生以下内容：

Collecting Fabric==1.4.3 (from -r fabfile/requirements.txt (line 1))
  Using cached Fabric-1.4.3.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 20, in <module>
      File "C:\Users\david\AppData\Local\Temp\1\pip-build-icytzvd1\Fabric\setup.py", line 7, in <module>
        from fabric.version import get_version
      File "C:\Users\david\AppData\Local\Temp\1\pip-build-icytzvd1\Fabric\fabric\version.py", line 104
        print get_version('all')
                        ^
    SyntaxError: invalid syntax

    ----------------------------------------
←[31mCommand "python setup.py egg_info" failed with error code 1 in C:\Users\david\AppData\Local\Temp\1\pip-build-icytzvd1\Fabric←[0m

我未经训练的眼睛看不到我能识别的语法错误。我查看了带有隐藏文件的C:\Users\david\AppData\Local\Temp\1，但没有pip-build-icytzvd1 文件夹。

我对 AWS 完全没有经验。如果这个问题的解决方案值得寻找，我在哪里可以找到解决方案？如果不值得为此寻找解决方案，是否有使用 Nginx、Gunicorn、PostreSQL 和 Amazon AMI 在 EC2 上手动部署 Django 的最新指南？

【问题讨论】：

  • 我的解决方案有效吗？
  • 很遗憾pip install Fabric没用，我刚才又试了一遍，把错误贴在了OP里。我放弃并手动完成所有操作，但如果它可以工作，我仍然想使用织物。
  • 这是在安装 pycrypto 依赖结构时出错。并且您似乎在 Windows 上。在 Windows 上安装库通常很痛苦。在 Windows 上搜索 pycrypto 或确切的错误可能会揭示一些东西。

【解决方案1】：

Fabric 1.4.3 这么旧。当前版本是1.10.2 真的很旧。您找不到该临时文件夹的原因是因为它是在您尝试安装fabric时由pip创建并在之后清除的。但是，您可以看到当前的version.py，或者如果您查看项目，您将能够看到您尝试安装的版本。当前版本代码看起来与您发布的有点不同：

print(get_version('all'))

但是我不明白为什么下面的代码也会产生错误。

print get_version('all')

您为什么不使用以下需求文件安装最新版本的 Frabric：https://github.com/fabric/fabric/blob/master/dev-requirements.txt？您可能已经安装了要求。在这种情况下，只需这样做

pip install Fabric

【讨论】：

  • 我看到这个话题是从 2015 年开始的，但是对于后代，我想提一下 python3 需要 print 与悬垂一起使用。
【解决方案2】：

我也遇到了同样的问题。 e5c5 是正确的。这是一个 pycrypto 安装问题。尝试将 pycrypto 安装为独立的 pip 安装。它可能会抛出错误消息并要求您安装 Visual Studio c++。

warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath. building 'Crypto.Random.OSRNG.winrandom' extension error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
