我收到此错误：

    TASK [pip] *********************************************************************
    failed: [default] (item=urllib3) => 
{"changed": false, "item": "urllib3", 
"msg": "Unable to find any of pip2, pip to use.  pip needs to be installed."}

根据建议，我运行以下命令：

ansible default -a "which pip"

我收到一个错误：

default | FAILED | rc=1 >>
non-zero return code

所以我想这意味着没有安装 pip。我尝试使用以下方法安装 pip：

ansible default -a "easy_install pip"

我收到以下错误：

default | FAILED | rc=2 >>
[Errno 2] No such file or directory

有任何想法吗？

更新 在 play_local.yaml 中，我有以下任务：

- name: Prepare system
  hosts: default
  become: yes
  gather_facts: false …

每次运行pylint(无论检查什么程序)都会产生以下错误消息:

我试图从这里在 macOS中使用python2创建虚拟环境。pip install virtualenv在终端中运行命令时，出现以下错误。

Could not find a version that satisfies the requirement virtualenv (from versions: )
No matching distribution found for virtualenv

在 MacOS (10.11.6) 上使用 pip 搜索或安装软件包时，我收到类似于下面重现的错误的 SSL 错误。

python2和python3都会出现这个问题。我通过www.python.org作为 Frameworks获得了版本（2.7.14 和 3.6.5）。pip 的版本是 9.0.1。这个问题是新的（2018 年 4 月），似乎与 OSX 的更新有关。

如何从这个问题中恢复？

$ pip2 search numpy

我正在尝试在公司计算机上安装熊猫。我试着做

pip install pandas

但是操作重试，然后超时。

然后我下载了软件包：

熊猫0.22.0-cp27-cp27m-win_amd64.whl

并安装：

pip install pandas-0.22.0-cp27-cp27m-win_amd64

但是我收到以下错误：

与pypi.python.org的连接超时。（connect timeout = 15）'）'：/ simple / pytz /重试（Retry（total = 0，connect = None，read = None，redirect = None，status = None））后被'ConnectTimeoutError（，'Connection'到pypi.python.org超时（连接超时= 15）'）'：/ simple / pytz /找不到满足要求pytz> = 2011k的版本（来自pandas == 0.22.0）（来自版本： ）找不到pytz> = 2011k的匹配分布（来自pandas == 0.22.0）

我对包做了同样的事情： pandas-0.22.0-cp27-cp27m-win_amd64.whl

我也尝试使用代理：

pip --proxy=IND\namit.kewat:xl123456@192.168.180.150:8880 install numpy

但是我无法得到熊猫。

当我尝试访问该网站时：https : //pypi.org/project/pandas/#files我可以在资源管理器上毫无问题地访问它

我正在使用MAC和python版本2.7.14

访问此 Github 页面后

我检查了 pip 版本：

C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>pip --version
pip 9.0.1 from C:\Users\xxxx\AppData\Local\Continuum\anaconda3\lib\site-packages (python 3.6)

和 ipykernel 版本：

C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>conda list ipykernel

我试过 conda forge …
