Error while installing robotframework

[shubham2141988]

Hi, I am trying to install robotframework with 'C:\Python27\Scripts>pip install robotframework' command and getting the following error:

NewConnectionError('<pip._vendor.requests.packages.urllib3.conne
ction.VerifiedHTTPSConnection object at 0x00000000035E1B70>: Failed to establish
a new connection: [Errno 11004] getaddrinfo failed',)': /simple/robotframework/

I have installed Python 2.7.12
wxPython 2.8.12.1
But I think wxPython is not properly installed as i got a popup (attached image) while installing it. So I think error while installing robotframework is due to this only.

Please help to resolve this issue. Below is error snapshot while installing robotframework

Hi @shubham2141988,

These error messages don't seem immediately related to the error dialog image provided.

The message

NewConnectionError('<pip._vendor.requests.packages.urllib3.conne
ction.VerifiedHTTPSConnection object at 0x00000000035E1B70>: Failed to establish
a new connection: [Errno 11004] getaddrinfo failed',)': /simple/robotframework/

indicates that the DNS lookup likely failed. This can happen for a number of reasons, for example:

1. Trying to access PyPI from a corporate network that blocks access
2. Network connectivity issues
3. A configured index-url in one of your configuration files is pointing to a location that is not accessible. See here for a command that can help troubleshoot this situation.

Since there are a few other issues in pip (#1876, #5380) tracking improving these error messages, I will close this issue but copy the details there to make sure the case is covered.
