Python pip无法安装任何内容

Question

我正在尝试用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

Answer 1

这是由于最近对Python.org网站的TLS弃用。

This回答有详细信息。

总结一下，升级点如下：

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

然后运行：

pip install pandas

Answer 2

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

此post可能有用

Answer 3

pip install -U pip

搜索了很长时间后，我尝试了this。
