折腾：
【未解决】Mac中启动PySpider
期间，去尝试从源码编译安装pycurl时，报错了：
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/opt/openssl/include;pip install pycurl --compile --no-cache-dir

去试试：
brew install openssl Updating Homebrew... Error: openssl@1.1 1.1.1d is already installed To upgrade to 1.1.1g, run `brew upgrade openssl@1.1`
已安装了。
brew info openssl openssl@1.1: stable 1.1.1g (bottled) [keg-only] Cryptography and SSL/TLS Toolkit https://openssl.org/ /usr/local/Cellar/openssl@1.1/1.1.1d (7,983 files, 17.9MB) Poured from bottle on 2019-11-01 at 11:50:22 From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/openssl@1.1.rb License: OpenSSL ==> Caveats A CA file has been bootstrapped using certificates from the system keychain. To add additional certificates, place .pem files in /usr/local/etc/openssl@1.1/certs and run /usr/local/opt/openssl@1.1/bin/c_rehash openssl@1.1 is keg-only, which means it was not symlinked into /usr/local, because macOS provides LibreSSL. ==> Analytics install: 595,026 (30 days), 1,985,779 (90 days), 6,696,740 (365 days) install-on-request: 71,954 (30 days), 265,896 (90 days), 863,719 (365 days) build-error: 0 (30 days)
看起来是安装到了：
/usr/local/Cellar/openssl@1.1/1.1.1d
去看看
open /usr/local/Cellar/openssl@1.1/1.1.1d
是否有对应头文件：
是有的。
以及确认：
ll /usr/local/opt/openssl/include ls: /usr/local/opt/openssl/include: No such file or directory
之前传入的路径不存在。
所以去加上对应路径
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/Cellar/openssl@1.1/1.1.1d;pip install pycurl --compile --no-cache-dir
好像搞错了，少加了个include
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/Cellar/openssl@1.1/1.1.1d/include;pip install pycurl --compile --no-cache-dir
即可成功安装：
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/Cellar/openssl@1.1/1.1.1d/include;pip install pycurl --compile --no-cache-dir Collecting pycurl Downloading https://files.pythonhosted.org/packages/ef/05/4b773f74f830a90a326b06f9b24e65506302ab049e825a3c0b60b1a6e26a/pycurl-7.43.0.5.tar.gz (216kB) 100% |████████████████████████████████| 225kB 1.3MB/s Installing collected packages: pycurl Running setup.py install for pycurl ... done Successfully installed pycurl-7.43.0.5
【总结】
此处Mac中之前已用brew安装过openssl，但是此处
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/opt/openssl/include;pip install pycurl --compile --no-cache-dir
报错：
In file included from src/docstrings.c:4: src/pycurl.h:165:13: fatal error: 'openssl/ssl.h' file not found # include <openssl/ssl.h>
直接原因：找不到openssl/ssl.h
根本原因：但实际上已安装了openssl，是有openssl/ssl.h的。只是传入的路径不对。
解决办法：找到已安装的openssl的实际路径，传入正确的路径。
步骤：
找到已安装的openssl的实际安装路径
brew info openssl
可以看到有：
/usr/local/Cellar/openssl@1.1/1.1.1d (7,983 files, 17.9MB)
其中的：
/usr/local/Cellar/openssl@1.1/1.1.1d
就是我们要的，此处openssl的实际安装路径
通过
open /usr/local/Cellar/openssl@1.1/1.1.1d
确认是有对应的：
/usr/local/Cellar/openssl@1.1/1.1.1d/include/openssl/ssl.h
这个文件的。
所以传入路径应该改为：
/usr/local/Cellar/openssl@1.1/1.1.1d/include
完整命令是：
export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/Cellar/openssl@1.1/1.1.1d/include;pip install pycurl --compile --no-cache-dir
即可。
