python - Centos 6.5安装wal-e报错

Question

在全新安装的 CentOS 6.5 (Python 2.6.6) 上，成功执行 pip install wal-e 后，运行 wal-e 会出现以下错误:

# wal-e
Traceback (most recent call last):
  File "/usr/bin/wal-e", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: argparse>=0.8

如果我执行 pip list argparse 我会得到一堆东西，包括 argparse 1.3.0

Answer 1

您缺少 argparse 包。 wal-e 正在寻找 0.8 或更高版本。

pip install argparse

另见: pip broke. how to fix DistributionNotFound error?
