Python pip 无法安装任何东西

Question

我正在尝试使用 pip 安装 pandas。

sudo pip install pandas

我收到以下错误：

➜  ~ which python
/usr/bin/python

➜  ~ python --version
Python 2.7.10

➜  ~ sudo pip install pandas
The directory '/Users/bdisha/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

我做错了什么？

Answer 1

这是由于最近 Python.org 网站弃用了 TLS。

这个答案有详细信息。

总而言之，升级 pip 如下：

curl https://bootstrap.pypa.io/get-pip.py | python

然后运行：

pip install pandas

我会尝试 sudo chown -R your_user_name /Users/bdisha/Library/Caches/pip/http 和 chown -R your_user_name /Users/bdisha/Library/Caches/pip

pip 和 python 都是垃圾，我从来没有用 pip 安装过任何东西。避免使用 python，它是一门死语言
