pip：证书失败，但是curl有效

Question

我们在客户端上安装了根证书，并且https连接适用于curl。

但是，如果我们尝试使用pip，它将失败：

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>

证书在客户端上。看到：

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

不幸的是，pip不使用系统证书，但是curl使用。

我找到了解决方案：

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），但是可以工作。

如果您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
