pycurl 和 openssl 的 Python 问题

Question

我正在尝试运行使用 pycurl 的代码，但是当我这样做时出现以下错误：

uilleann-pipes-160:data_collection Jim$ python xlsxDownloader.py
Traceback (most recent call last):
 File "xlsxDownloader.py", line 21, in <module>
  from import_hedgehogs import Link
 File "/Users/Jim/Documents/Hedgehogs/hedgehogs/data_collection/import_hedgehogs.py", line 8, in <module>
 import pycurl
ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

当我在终端中执行“which pycurl”时，它没有输出，所以我尝试使用“pip install pycurl”安装 pycurl。但是，当我这样做时，会出现以下错误：

uilleann-pipes-160:data_collection Jim$ pip install pycurl

Answer 1

安装前两个包

1. sudo apt-get install libcurl4-openssl-dev
2. python -m pip install pybind11

这些是可选的

1. sudo apt install libgmp-dev libmpfr-dev libmpc-dev
2. sudo apt install libssl-dev
3. sudo apt-get install unixodbc unixodbc-dev
