如何使用 pip 安装 requests 模块？ pip 是否正确安装？

Question

不知道pip是否安装正确。 我用的是easy_install

它将 pip 脚本安装到： /Library/Frameworks/Python.framework/Versions/2.7/bin

但是，当我输入“pip”时，我会得到一个命令列表和常规选项 不是错误

但是当我尝试安装请求时，我得到：

谁能给我解释一下这里发生了什么？

Answer 1

您的所有消息都报告相同的问题：

Cannot fetch index base URL https:// pypi.python. org/simple/

注意https:// 和pypi... 之间的空格

您似乎在某处配置了 --index，但它的值有误。

最好是去掉所有影响配置的手段，以“干净”的方式运行

Configuration 描述以下方法

• 配置文件
• 环境变量

由于命令行开关优先，您可以尝试：

$ pip install requests --index "http://pypi.python.org/"

但如果你成功了，你一定要研究一下，你在哪里搞砸了你的 pip 配置。
