安装的 Electrum 无法启动,现在 Electrum-Ltc 不再工作 - 更新 python/urllib3?

我按照以下说明安装了 electrumhttps://electrum.org/#download

安装依赖项: sudo apt-get install python3-setuptools python3-pyqt5 python3-pip

安装 Electrum: sudo pip3 installhttps://download.electrum.org/3.1.1/Electrum-3.1.1.tar.gz

操作系统是linux mint 17

当我通过应用程序菜单单击金币图标时,没有任何反应。我已经安装了 electrum-ltc 并且它正在工作。由于安装了 electrum,它将无法运行。

如果我尝试通过命令行启动它,我会收到以下错误:

$ ./金币

/usr/local/lib/python3.4/dist-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.7.1) or chardet (2.2.1) doesn't match a supported version!
  RequestsDependencyWarning)
Error: cannot import name 'DependencyWarning'. Try 'sudo pip install <module-name>'

尝试更新 urllib3 和 chardet 我收到以下错误:

如何更新 urllib3?

或者问题与我安装的依赖项有关?

“安装依赖项:sudo apt-get install python3-setuptools python3-pyqt5 python3-pip”

在我安装上面的 Electrum (btc) 依赖项之前,Electrum-ltc 工作正常。

你的问题是你的系统中有两个 python 安装,python2.7并且python3.4.该pip命令引用 的包管理器python2.7,因此当您发出 时pip install urllib3,您正在尝试安装/更新urllib3错误版本的 Python 的包 - 用于pip3安装/更新 Python 3 的包:

$ pip3 install chardet urllib3 --upgrade --user

顺便说一句,我不想​​调用sudo pip/sudo pip3因为一些 python 包是由apt(如pip它本身setuptoolsrequests)管理的,所以如果你首先安装了

$ apt install python3-setuptools

然后开始sudo pip3 install打包,迟早你会破坏东西,因为setuptools它被许多 python 包声明为依赖项,并且你会意外地覆盖python3-setuptools安装。sudo apt install如果apt没有提供您需要的软件包或提供旧版本,那么它会更安全pip install --user
