I am trying to use pip from behind a corporate firewall, and not having any luck.
I have set the http_proxy
and https_proxy
environment variables. wget works, but not pip.
I tried this ...
sudo -E pip install virtualenv
with these proxies ...
export http_proxy=myproxyname.mydomain.com:8080
export https_proxy=myproxyname.mydomain.com:8080
... and got a long stacktrace which ended with this
/requests/packages/urllib3/poolmanager.py", line 214, in __init__
'Not supported proxy scheme %s' % self.proxy.scheme
AssertionError: Not supported proxy scheme None
I looked at the poolmanager.py source. It looks like it is requiring the proxy variables to begin with a scheme. So I tried again with the following proxies ...
export http_proxy=http://myproxyname.mydomain.com:8080
export https_proxy=https://myproxyname.mydomain.com:8080 (also tried this with http://)
... and I get the following error
Downloading/unpacking virtualenv
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement virtualenv
Cleaning up...
No distributions at all found for virtualenv
Storing debug log for failure in /root/.pip/pip.log
This is the same error I get when I do not have a proxy at all, though I get it much faster when the proxies are set.
When I try wget ...
wget --no-check-certificate https://pypi.python.org/simple/
It works fine, so I think the proxies themselves seem ok, unless I try them with pip.
Using the --proxy
option instead of envvars did not help. Same results.
Any ideas?
Thanks, Bean
Use the --trusted-host argument.
I figured out how to get it to work with me behind my corporate firewall using the --trusted-host argument.
My first attempt was this:
pip install matplotlib
and the failed text was this:
Could not fetch URL https://pypi.python.org/simple/matplotlib/ : There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645) - skipping
So then I tried this which worked:
pip3.5 install matplotlib --trusted-host pypi.python.org
I had to set all this in Windows to make it work.
set http_proxy=http://proxy.corp.com:8083
set https_proxy=http://proxy.corp.com:8083
set all_proxy=http://proxy.corp.com:8083
set no_proxy=localhost,.corp.com
set HTTP_PROXY=http://proxy.corp.com:8083
set HTTPS_PROXY=http://proxy.corp.com:8083
set ALL_PROXY=http://proxy.corp.com:8083
set NO_PROXY=localhost,.corp.com
set PATH=c:\python27\scripts;c:\python27\;%PATH%
Please replace proxy.corp.com:8083 with your http proxy server.
After that I use pip install numpy
[Last ".corp.com" was missing a period (fixed it).... by the way, after MUCH hair-pulling from behind our corporate firewall, THIS solution was the only one that worked!]
This worked for me (on linux centOS)
export HTTP_PROXY=http://myusr:mypswd@myproxyname.mydomain.com:8080
export HTTPS_PROXY=https://myusr:mypswd@myproxyname.mydomain.com:8080
sudo -E pip3 install --proxy http://myusr:mypswd@myproxyname.mydomain.com:8080 virtualenv
pip
有一个设置代理的选项,所以以下应该适合你:
sudo -E pip install --proxy="myproxyname.mydomain.com:8080" virtualenv
Try adding "http://" before the proxy hostname:
sudo -E pip install --proxy="http://myproxyname.mydomain.com:8080" virtualenv
this is working behind a proxy
sudo -E pip --proxy username:password@ http://IP:port install
On windows go to "Internet Properties" ---> "Connection" ---> "LAN Settings" and check the address (if it is a wpad.dat file, download it and look for "ProxyPort" and "ProxyServer").
Then try:
pip --proxy http://*user*:*password*@P*roxyServer*:*ProxyPort* install *module*
