重新安装python时出现的问题

这是用于记录一次重装系统后安装python遇见的问题

今天重装了电脑的系统，原先的win10 似乎有些问题，重装后想装回python，发现安装numpy包和pandas包时有些问题。
安装命令

pip install pandas

显示报错：

PS F:\python\Data_Ana\names> pip install pandasDownloading/unpacking pandasCleaning up...Exception:Traceback (most recent call last):  File "C:\Python27\lib\site-packages\pip\basecommand.py", line 122, in main    status = self.run(options, args)  File "C:\Python27\lib\site-packages\pip\commands\install.py", line 278, in run    requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, bundle=self.bundle)  File "C:\Python27\lib\site-packages\pip\req.py", line 1197, in prepare_files    do_download,  File "C:\Python27\lib\site-packages\pip\req.py", line 1375, in unpack_url    self.session,  File "C:\Python27\lib\site-packages\pip\download.py", line 572, in unpack_http_url    download_hash = _download_url(resp, link, temp_location)  File "C:\Python27\lib\site-packages\pip\download.py", line 433, in _download_url    for chunk in resp_read(4096):  File "C:\Python27\lib\site-packages\pip\download.py", line 421, in resp_read    chunk_size, decode_content=False):  File "C:\Python27\lib\site-packages\pip\_vendor\requests\packages\urllib3\response.py", line 240, in stream    data = self.read(amt=amt, decode_content=decode_content)  File "C:\Python27\lib\site-packages\pip\_vendor\requests\packages\urllib3\response.py", line 187, in read    data = self._fp.read(amt)  File "C:\Python27\lib\httplib.py", line 573, in read    s = self.fp.read(amt)  File "C:\Python27\lib\socket.py", line 380, in read    data = self._sock.recv(left)  File "C:\Python27\lib\ssl.py", line 714, in recv    return self.read(buflen)  File "C:\Python27\lib\ssl.py", line 608, in read    v = self._sslobj.read(len or 1024)SSLError: ('The read operation timed out',)Storing debug log for failure in C:\Users\Aukuno\pip\pip.log

查了查发现是依赖库和编译器的问题：
python2.7要求电脑配备Ms的Microsoft Visual C++ 2008。

安装后发现还没有解决问题。
这个时候瞄到Dos控制台显示Ms有专门用于支持python2.7的编译器包，链接在此：

下载安装后问题解决。
