AttributeError:'module'对象没有运行pip的属性'python_implementation'

Question

我用Python设置工具安装了Cygwin.当我尝试运行pip install时,awscli我收到以下错误:

$ pip install awscli
Traceback (most recent call last):
  File "/usr/bin/pip", line 8, in <module>
    load_entry_point('pip==1.5.4', 'console_scripts', 'pip')()

    'python_implementation': platform.python_implementation,
AttributeError: 'module' object has no attribute 'python_implementation'

我在路径中遗漏了什么,或者我的Python实现是否被忽略了？

Answer 1

你的python应用程序中有一个名为“/platform”的文件夹吗？

如果你这样做，它将作用域阴影原生 python“平台”模块。当您使用的模块尝试获取有关系统的信息时，它们将返回一个空对象。这通常会导致以下错误：

AttributeError: 'module' object has no attribute 'version'

AttributeError: 'module' object has no attribute 'machine'

AttributeError: 'module' object has no attribute 'python_implementation'

只需将“/platform”文件夹重命名为其他名称即可解决问题。

重新安装pip可能会修复它,尝试使用easy_install:

sudo easy_install pip
