使用pip安裝requests包時，發生報錯，起初以為是防火牆的問題，結果發現是python中配置檔案的問題。
報錯內容如下：
/usr/local/lib/python2.7/dist-packages/pip/req/req_set.py", line 129, in prep_for_dist self.req_to_install.run_egg_info() file "/usr/local/lib/python2.7/dist-packages/pip/req/req_install.py", line 412, in run_egg_info self.setup_py, self.name, file "/usr/local/lib/python2.7/dist-packages/pip/req/req_install.py", line 387, in setup_py import setuptools # noqa file "/root/.local/lib/python2.7/site-packages/setuptools/
init
.py", line 12, in import setuptools.version file "/root/.local/lib/python2.7/site-packages/setuptools/version.py", line 1, in import pkg_resources file "/root/.local/lib/python2.7/site-packages/pkg_resources/

.py", line 72, in import packaging.requirements file "/root/.local/lib/python2.7/site-packages/packaging/requirements.py", line 59, in marker_expr = originaltextfor(marker_expr())("marker") typeerror:
call
() takes exactly 2 arguments (1 given)
解決辦法：
在/usr/lib/python2.7目錄下找到requirements.py
將marker_expr = originaltextfor(marker_expr())("marker")替換成marker_expr = originaltextfor(marker_expr)("marker")即可。
