python - 无法在 Python 3 上安装 wsgiref

Question

我在安装 wsgiref 时遇到问题:

$ python --version
Python 3.6.0 :: Anaconda 4.3.1 (x86_64)
$ pip --version
pip 9.0.1 from /anaconda/lib/python3.6/site-packages (python 3.6)

我的requirement.txt文件如下所示。

numpy==1.8.1
scipy==0.14.0
pyzmq==14.3.1
pandas==0.14.0
Jinja2==2.7.3
MarkupSafe==0.23
backports.ssl-match-hostname==3.4.0.2
gnureadline==6.3.3
ipython==2.1.0
matplotlib==1.3.1
nose==1.3.3
openpyxl==1.8.6
patsy==0.2.1
pyparsing==2.0.2
python-dateutil==2.2
pytz==2014.4
scikit-learn==0.14.1
six==1.7.3
tornado==3.2.2
wsgiref==0.1.2
statsmodels==0.5.0

当我运行 pip install -r requirement.txt 时，出现了这个错误

Collecting wsgiref==0.1.2 (from -r requirements.txt (line 20))
  Using cached wsgiref-0.1.2.zip
    Complete output from command python setup.py egg_info:

我尝试运行 pip install --upgrade setuptools 和 sudo easy_install -U setuptools 但都不起作用。我该如何解决这个问题？

wsgiref 已经作为标准库包含在 Python 3 中...因此，如果您正在尝试使用 Python 3，请继续并导入 wsgiref 即可。
