Question

我目前正在http://proctor.andela.com/进行一些编程测试，我的OOP问题代码在pyCharm和Idle中工作正常/正确但是在测试时＃39;提供的编辑器中的代码，我不断收到此错误

/ bin / sh：1：python / nose2 / bin / nose2：not found

因此我无法提交我的代码。

我尝试了以下内容：

已退出并返回课程页面 - 无变化。
将我的互联网更改为更快/更可靠的互联网（在某个地方看到帖子以确保互联网连接稳定 - 我使用的是有时不稳定的3G连接） - 没有变化。
重新编写了我的代码 - 没有变化。

进一步的研究表明，这是由用于评估代码的unittest带来的，这是否意味着这是一个服务器问题？

我将很感激此事的任何前进方向，因为测试是时间限制的。

编辑/附加信息 移到另一个实验室并仍然得到相同的错误。这是否指向环境配置错误或服务器端错误？

我的当前设置是：

Linux Mint 17.3 64位。按建议通过Google Chrome进行测试。使用Firefox时出现相同的错误。

我的代码，供参考：

class BankAccount(object):

    def deposit(self):
       pass
    def withdraw(self):
       pass

class SavingsAccount(BankAccount):
    def __init__(self):
       self.balance = 500

    def deposit(self, amount):
        if amount < 0:
           return 'Invalid deposit amount'
        else:
           self.balance += amount
           return self.balance
    def withdraw(self, amount):
        if amount < 0:
           return 'Invalid withdraw amount'

        elif amount > self.balance:
           return 'Cannot withdraw beyond the current account balance'

        elif (self.balance - amount < 500):
           return 'Cannot withdraw beyond the minimum account balance'

        else:
           self.balance -= amount
           return self.balance

class CurrentAccount(BankAccount):

    def __init__(self):
        self.balance = 0
    def deposit(self, amount):
        if amount < 0:
            return 'Invalid deposit amount'
        else:
            self.balance += amount
            return self.balance
    def withdraw(self, amount):
        if amount < 0:
            return 'Invalid withdrawal amount'
        elif amount > self.balance:
            return 'Cannot withdraw beyond the current account balance'
        else:
            self.balance -= amount
            return self.balance

FINAL EDIT＆amp; CLOSE （Andela）确认测试平台确实存在严重问题，导致其脱机维护。因此，我可以通过确认这是服务器端问题来结束这个问题。谢谢所有回复/评论的人。

好吧那么：看看test.spy代码非常仔细地看它，因为它与解决方案有很多关系。我发现了这个错误：

这个告诉你，你有某些事要证明/测试..

Answer 2

没有隐藏的测试。 unittest应该导入类，它不会。尝试复制测试并放置导入类，然后运行unittest，最有可能的代码将在另一个环境中返回。这有点不合时宜

Answer 3

所有测试都返回错误/bin/sh: 1: python/nose2/bin/nose2: not found. 我想这与那些家伙有关。我猜所有代码都没有相同的错误

在线OOP测试：python / nose2 / bin / nose2：找不到
