python - pip:证书失败，但 curl 有效

Question

我们在客户端安装了我们的根证书，并且 https 连接适用于 curl。

但是如果我们尝试使用pip，它会失败:

Could not fetch URL https://installserver:40443/pypi/simple/pep8/:
There was a problem confirming the ssl certificate: 
<urlopen error [Errno 1] _ssl.c:499: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed>

证书在客户端。见:

(foo_fm_qti)foo_fm_qti@vis-work:~$ curl -v https://installserver:40443/pypi/simple/pep8/
* About to connect() to installserver port 40443 (#0)

很遗憾 pip 不使用系统证书，但 curl 可以。

我找到了解决办法:

pip --cert /etc/ssl/certs/FOO_Root_CA.pem install pep8

这不是很好(curl 和其他库在不添加参数的情况下找到证书)但可以。

如果不想使用命令行参数，可以在~/.pip/pip.conf中设置证书:

[global]
cert = /etc/ssl/certs/Foo_Root_CA.pem
