pip安装失败，并带有/usr/bin/clang:没有这样的文件或目录 [英] pip install fails with /usr/bin/clang: No such file or directory

问题描述

我正在将自己的开发环境迁移到10.8，但是pip出现了问题.

I am migrating my dev environment to 10.8, however I am having issues with pip.

具体地说，我使用的是virtualenvs/virtualwrapper，但不能使用pip install psycopg2，在构建psycopg2._psycopg扩展程序时，我得到:

Specifically, I'm using a virtualenvs/virtualwrapper but cannot pip install psycopg2, and during the building of the psycopg2._psycopg extension, I get:

unable to execute /usr/bin/clang: No such file or directory
error: command '/usr/bin/clang' failed with exit status 1

任何人都可以提供解决方案吗?

Can anyone offer a solution to this?

推荐答案

之所以会发生这种情况，是因为升级后您没有重新安装命令行工具.

This probably happens because you did not re-install the Command Line Tools after upgrading.

通常，应该将XCode升级到最新版本(4.4)(我相信，当我更新到10.8时，我还更新了一堆其他应用程序，包括XCode).更新后，您需要重新安装命令行工具.现在，可以通过XCode中的设置来完成此操作:

Usually XCode should be upgraded to the latest version (4.4) (I believe when I updated to 10.8 I also updated a whole bunch of other applications, including XCode). After the update you need to re-install the Command Line Tools. This can now be done via a setting in XCode:

转到首选项->下载"并安装命令行工具".

Go to "Preferences -> Downloads" and install "Command Line Tools".

现在，在安装需要编译的软件包时，您应该再没有其他问题了.

Now you should have no more problems when installing packages that need to be compiled.
