unittest安装报错找不到满足要求的版本

Question

有人可以帮我解决这个错误信息吗：

Could not find a version that satisfies the requirement unittest

我安装了最新的 Python 和 PyCharm 并尝试安装软件包 unittest 但出现上述错误。到目前为止，我对 Python 的体验有点像 dll 地狱...

Answer 1

如果你试过这个：

$ pip install unittest
Collecting unittest

  Could not find a version that satisfies the requirement unittest (from versions: )
No matching distribution found for unittest

出现错误是正常的，因为 unittest is not a valid package on Pypi. The only distributable is unittest2-0.0.0.tar.gz but the name is not correct, it should be unittest-0.0.0.tar.gz (without "2"). In fact I think it's an error and if you want to use this one you need to install unittest2（这是 Python 2.6 的 unittest 的反向移植）。

但是unittest是标准模块，不需要安装:

$ python -m unittest

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
