Python PIP install: Insecure platform warning

Last updated: December 21st, 2016

Normally, installing a python module and its dependencies is done via Pip. If HTTPS is blocked in private networks, then things might get tricky and you get the following message.

InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.

To bypass this, you can issue the below command to trust pypi.python.org

$ pip install –trusted-host pypi.python.org Flask

To make sure that the needed module is installed, check it by

$ pip freeze

Git: error: RPC failed; curl 55 SSL_write() returned SYSCALL,

Last updated: December 16th, 2016

Git uses “Transfer-encoding” in POST requests and some proxy servers do not support this encoding by default. When large files are pushed, the git client requires higher http.postBuffer setting.

Increase the buffer size to see if the issue is related to it.

$ git config –global http.postBuffer 134217728

Git: SSL certificate problem: unable to get local issuer certificate

Last updated: December 16th, 2016

You get this message when the system is behind a firewall and when the security certificates are blocked.

There are two ways to overcome this message and to enable a git pull or git clone.

i) Issue the below command from git bash

$ git config –global http.sslVerify false


ii) Add http block in “gitconfig” file to avoid ssl verification

sslVerify = false
sslCAinfo = /bin/curl-ca-bundle.crt
