如何使用pip解决ReadTimeoutError：HTTPSConnectionPool（host ='pypi.python.org'，port = 443）？

我最近需要安装一些软件包

pip install futurepip install scikit-learnpip install numpypip install scipy

我sudo在他们之前也尝试过writin ，但是所有这些都以红线显示了以下错误：

Exception:Traceback (most recent call last):  File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main    status = self.run(options, args)  File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 290, in run    requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, bundle=self.bundle)  File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1198, in prepare_files    do_download,  File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1376, in unpack_url    self.session,  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 572, in unpack_http_url    download_hash = _download_url(resp, link, temp_location)  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 433, in _download_url    for chunk in resp_read(4096):  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 421, in resp_read    chunk_size, decode_content=False):  File "/usr/lib/python2.7/dist-packages/urllib3/response.py", line 256, in stream    data = self.read(amt=amt, decode_content=decode_content)  File "/usr/lib/python2.7/dist-packages/urllib3/response.py", line 201, in read    raise ReadTimeoutError(self._pool, None, ''Read timed out.'')ReadTimeoutError: HTTPSConnectionPool(host=''pypi.python.org'', port=443): Read timed out.Storing debug log for failure in /root/.pip/pip.log''

答案1

耶！我找到了答案。只需在安装中使用–default-timeout = 100参数即可。例如

sudo pip install --default-timeout=100 future

"from pymongo import Connection" (to import mongo.connection using python) , got "500 Internal Server Error"

I created the /var/www/cgi-bin/test.py in my web server machine (Linux). The service of mongoDB "mongod" is running.

When I run the test.py locally, "./test.py", I could get the correct result.

But when I use the URL: http://xxxxxx.compute-1.amazonaws.com/cgi-bin/python_test/test.py to run the test.py, I will get the "500 Internal Server Error". 

If I remove the line "from pymongo import Connection", and use the URL above to access, I won''t get the 500 Internal server error. So, it should be the problem when I import the pymongo.connection.

Is it the problem of any configuration issue? Thanks so much for your help

========== test.py ==============

#!/usr/bin/python
import cgi
import sys
sys.path.append("/home/ec2-user/mongo-python-driver-2.6.3/")

#import pymongo.connection
from pymongo import Connection
def main():
        print "Content-type: text/html\r\n\r\n"
        form = cgi.FieldStorage()
        name = form.getvalue(''ServiceCode'')
#       name = "abcddd"
#       con = Connection()
#       db = con.test
#       posts = db.post

#       print name
        if form.has_key("ServiceCode") and form["ServiceCode"].value!="":
                print"<h1>Hello", form["ServiceCode"].value,"</h1>"
        else:
                print"<h1>Error! Please enter first name. </h1>"

(python pip 安装第三方库超时问题（raise ReadTimeoutErrorself._pool, None, ''Read timed out.'')

(python pip 安装第三方库超时问题（raise ReadTimeoutErrorself._pool, None, ‘Read timed out.’)

pip 工具安装
百度经验链接: pip 安装及环境变量配置.

pip 下载超时处理
aise ReadTimeoutError(self._pool, None, ‘Read timed out.’)

方案一：对于比较小的库，可以延时处理

-------- pip --default-timeout=100 install -U pip
-------- pip --default-timeout=100 install 第三方库名

方案二：更换安装源

------------ 网上可以查找很多豆瓣源
如 https://pypi.tuna.tsinghua.edu.cn/simple/

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyecharts
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple 库名
出错使用这种 ：pip install --index-url https://pypi.tuna.tsinghua.edu.cn/simple/ lightgbm

方案三：下载离线包

python 所有库：(https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml)

--------- 然后通过 pip install 保存路径 / 加上下载的文件名 进行安装
（如 pip install C:\Users\HP\Desktop\scikit_image-0.14.1-cp37-cp37m-win32.whl）

connect to host ssh.github.com port 22: Connection timed out解决方法

ssh: connect to host ssh.github.com port 22: Connection timed out
ssh：连接到主机github.com端口22：连接超时

提示：连接到主机git@github.com端口20超时~~~
百度之后，可能是端口被占用;
解决办法：
在./ssh 下找到congfig文件，如果没有就创建一个

在config文件中复制下面代码：

Host github.com

User git

Hostname ssh.github.com

PreferredAuthentications publickey

IdentityFile ~/.ssh/id_rsa

Port 443

然后在执行
ssh -T git@github.com 查看是否可以链接；

成功

是这样的，最近我在开发Api（重构），用的数据库是Sqlserver，使用的Orm是 SqlSugar（别问我为什么选这个，boss选的同时我也想支持国人写的东西，且文档也很全）。

被催的是，写好了程序本地（windows10 pro 64 bit）运行正常，一部署到测试机器(centos7.2 64 bit)就报错：

报错1

An unhandled exception occurred while processing the request.

SqlSugarException: English Message : Connection open error . Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting to create multiple active connections. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=48; handshake=124; [Login] initialization=0; authentication=0; [Post-Login] complete=14000; Chinese Message : 连接数据库过程中发生错误，检查服务器是否正常连接字符串是否正确，实在找不到原因请先Google错误信息：Connection Timeout Expired.

The duration spent while attempting to connect to this server was - [Pre-Login] initialization=48; handshake=124; [Login] initialization=0; authentication=0; [Post-Login] complete=14000; .

如图：

wtf！！！:为毛本地好好的，一丢到linux测试机（后面简称测试机）就出问题？？？

然后，我开始痛苦的排查了，从环境、框架，依赖注入，数据库网络；

telnet ping啊那些不用说了；

1、换台测试机 --> 测试机一样报错（排除本机玄学原因）；

2、更新SqlSugar版本，从4.9.7更新到4.9.8.1--> 本地正常、测试机一样报错（基本排除驱动特地版本的bug）；

3、用程序连接查询同网段的其他数据库 --> 本地正常、测试机一样报错（基本也排除网络原因）；

4、连接我自己远程服务器的数据库 --> 本地正常、测试机正常--（排除linux驱动工作不正常或者程序时bug）

最后，我想想一直报超时。我都没增加超时时间（默认应该是15秒），我在连接字符串里面加了一个

Connect Timeout=300;//5分钟的超时时间

得，报的错变成了：

报错2

An unhandled exception occurred while processing the request.

SqlSugarException: English Message : Connection open error . A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 35 - An internal exception was caught) Chinese Message : 连接数据库过程中发生错误，检查服务器是否正常连接字符串是否正确，实在找不到原因请先Google错误信息：A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 35 - An internal exception was caught).

SqlSugar.AdoProvider.GetDataReader(string sql, SugarParameter[] parameters)

如图：

各种玄学的非玄学的方法都找完了，差点想提前打包回家了，我突然灵光一闪？？会不会数据库版本问题！！！

最后发现了这个，

.net core 的System.Data.SqlClient支持的最低SqlServer版本是2008 r2 SP3,小于这个版本的就会报这个错。

https://github.com/dotnet/corefx/issues/9719

结论：

.netcore 连接使用sqlserver遇到以上报错1、报错2的同学,需注意：.net core 的System.Data.SqlClient支持的最低SqlServer版本是2008 r2 SP3请先检查数据库版本。

呼~这个鬼问题浪费了我整整两天+（3个熬夜）。
