The following post helped me get it working:

Had to install "command line tools" for Xcode and then I was able to pip install with the virtualenv just the same as the heroku tutorial.

Install <code>postgres</code> with <code>brew</code>:

<pre><code>brew install postgres
</code></pre>

Then, in your virtualenv install <code>psycopg2</code> with this command:

<pre><code>ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install psycopg2
</code></pre>

Just would like to share. The following code worked for me:

<pre><code>env LDFLAGS='-L/usr/local/lib -L/usr/local/opt/openssl/lib
-L/usr/local/opt/readline/lib' pip install psycopg2==2.5.2
</code></pre>

I am using macOS Sierra and psql 9.6.1.

I got the lib path from the <code>pg_config</code> command.

blocks|key|411287|text|我尝试了上面所有的解决方案，但唯一能解决这个问题的就是通过官方App+Store更新Xcode+CLI实用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|411288|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I tried all of the above solutions but the only thing that resolved the issue for me is simply updating Xcode CLI utilities through the official App Store.

blocks|key|411312|text|解决方法是安装所有的‘intsall+copg2-binary’包|type|unstyled|depth|inlineStyleRanges|entityRanges|data|411313|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The workaround is to intsall 'psycopg2-binary' package

blocks|key|411362|text|我试了那么多东西，都没成功。但是，如果您在Mojave上使用Xcode+CLI工具，并且在安装psycopg2时遇到问题，请尝试以下命令，然后再次尝试安装psycopg2。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|411363|sudo+installer+-pkg+/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg+-target+/|code-block|syntax|javascript|411364|这被描述为一个莫哈韦问题：Pillowissue|offset|length|411365|在我的例子中，这解决了问题。|411366|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/python-pillow/Pillow/issues/3438#issuecomment-435169249^0|0|0|D|B|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@$I|X|J|Y|1|Z]]|A|$]]|$1|K|3|L|5|6|7|10|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

I was trying so many things and nothing worked. However, if you use Xcode CLI Tools on Mojave and have a problem installing psycopg2, try the following command and try to install psycopg2 again.

<pre><code>sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
</code></pre>

This was described as a Mojave Issue: <a href="https://github.com/python-pillow/Pillow/issues/3438#issuecomment-435169249" rel="nofollow noreferrer">Pillowissue</a> 

In my case, this solved the issue.

blocks|key|411488|text|通用LDFLAGS变量集|type|unstyled|depth|inlineStyleRanges|entityRanges|data|411489|只需在安装之前导出LDFLAGS，以下是适用于OS+X的通用命令(我相信任何有相同错误的LINUX系统)：|411490|+LDFLAGS=`echo+$(pg_config+--ldflags)`+pip+install+psycopg2|code-block|syntax|javascript|411491|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<h2>Generic LDFLAGS variable set</h2>
Just export LDFLAGS before installing it, here is generic command which shall work for OS X (and I believe any LINUX system which has same error):

First this:
<code>pip install psycopg2-binary</code>
and then:
<code>pip install psycopg2</code> worked.

I am following Heroku's tutorial to deploy a Django app: <a href="http://devcenter.heroku.com/articles/django#prerequisites">http://devcenter.heroku.com/articles/django#prerequisites</a>. 

Everything is working fine until I get to this part: 

<pre><code>$ pip install Django psycopg2
</code></pre>

I can install Django by itself, but the probelm is with psycopg2. 

I keep getting this error: 

<pre><code>ld: library not found for -lpq

collect2: ld returned 1 exit status

ld: library not found for -lpq

collect2: ld returned 1 exit status

lipo: can't open input file: /var/folders/_4/p6l0y0t51hd4xbq7llbyshmw0000gn/T//cc0L10mI.out (No such file or directory)

error: command 'gcc-4.2' failed with exit status 1
</code></pre>

I've installed PostgreSQL 9.1 on my machine. 

Also, in the output, there are bunch of lines like this: 

<pre><code>gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.4.4 (dt dec pq3 ext)" -DPG_VERSION_HEX=0x090004 -DPSYCOPG_EXTENSIONS=1 -DPSYCOPG_NEW_BOOLEAN=1 -DHAVE_PQFREEMEM=1 -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I. -I/usr/include -I/usr/include/postgresql/server -c psycopg/typecast.c -o build/temp.macosx-10.6-intel-2.7/psycopg/typecast.o
</code></pre>

I'm not really sure what it means, but I do notice that it has "macosx-10.6" in it so I'm wondering if that could be the issue? I'm on 10.7. 

Thanks in advance for your help.
