pip安装：ssl certifi有问题

Question

我使用的是Debian9，我已经安装了Python3.6.2和PIP9.0.1。不过，当我想安装诸如numpy、scipy或matplotlib之类的模块时，还是有问题的。当我使用pip install命令时，总是会出现以下错误：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting numpy Could not fetch URL https://pypi.python.org/simple/numpy/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping Could not find a version that satisfies the requirement numpy (from versions: ) No matching distribution found for numpy

我试过这门课的最高答案（pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)"），但没有成功。事实上，我得到了同样的错误信息。

不幸的是，这个命令也失败了。

pip install --index-url=http://pypi.python.org/simple/numpy --trusted-host pypi.python.org numpy

我希望有人能解决我的问题。提前谢谢你的帮助。：天

Answer 1

我运行以下命令来解决问题

$ curl https://bootstrap.pypa.io/get-pip.py >> get-pip.py $ python get-pip.py

Answer 2

1. 取消对Python-3.6.2/Modules/Setup中209-212行的注释

   SSL=/usr/local/ssl _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto

2. 确保已安装libssl dev

3. 转到Python目录并执行./configure、make和make install

4. 使用以下命令安装软件包：pip install --trusted-host pypi.python.org packageName

希望能帮上忙。：天
