环境
Mac OS 10.11.6 pyenv 1.2.8 Python 2.7.5
问题
$ pip install lxml==3.6.4 Failed to build lxml ld: file not found: python.exe clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command 'clang' failed with exit status 1 ---------------------------------------- Failed building wheel for lxml
解决：
2.7.5 是对应的版本号
$ export p=/Users/$(whoami)/.pyenv/versions/2.7.5 $ sed -i -e "s~-bundle_loader python.exe~-bundle_loader ${p}/bin/python2.7~g" "$p/lib/python2.7/_sysconfigdata.py"
再次安装成功了
$ pip install lxml==3.6.4 Successfully built lxml Installing collected packages: lxml Found existing installation: lxml 4.3.3 Uninstalling lxml-4.3.3: Successfully uninstalled lxml-4.3.3 Successfully installed lxml-3.6.4
安装普通包没问题，比如requests ,而需要编译的包，比如lxml就报错
找了很多地方这是因为我使用的是 pyenv , 这应该是它的小问题，不过好在有人已经解决了
