python - 使用 pip 安装 tweepy 模块

Question

我对编码相对陌生，但感觉我对基础知识有深入的了解。我希望使用 python 来使用 tweepy 模块来试验 twitter，但我在安装它和其他模块时遇到了麻烦，在命令行中使用 pip。

在命令行(macOS Sierra 上的终端)中输入 pip pip install tweepy 会返回本文末尾的错误字符串。

如果有人能解释为什么我无法安装任何模块，我将非常感激。

提前致谢。

如上所述，您需要 root 访问权限来存储 pip 包。

Python 3.x:

sudo pip3 install tweepy

Python 2.x:

sudo pip install tweepy

您还可以使用 Git 从 Github 克隆存储库并手动安装:

git clone https://github.com/tweepy/tweepy.git
cd tweepy
python setup.py install

或者您可以使用virtualenv

"What if you can't install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn't share libraries with other virtualenv environments (and optionally doesn't access the globally installed libraries either)."

基本上，它允许您为每个项目创建一个隔离的环境，并且有助于解决您遇到的权限问题。
