安裝的 Electrum 無法啟動，現在 Electrum-Ltc 不再工作 - 更新 python/urllib3？
我按照https://electrum.org/#download的說明安裝了電子
安裝依賴項： sudo apt-get install python3-setuptools python3-pyqt5 python3-pip
安裝 Electrum：sudo pip3 install https://download.electrum.org/3.1.1/Electrum-3.1.1.tar.gz
作業系統是 linux mint 17
當我通過應用程序菜單點擊電子圖示時，沒有任何反應。我已經安裝了電子 ltc 並且它正在工作。由於安裝了電子，它不會執行。
如果我嘗試通過命令行啟動它，我會收到以下錯誤：
$ ./電子

還是問題與我安裝的依賴項有關？
“安裝依賴項：sudo apt-get install python3-setuptools python3-pyqt5 python3-pip”
在我為 Electrum (btc) 安裝上述依賴項之前，Electrum-ltc 工作正常。
您的問題是您的系統中有兩個 python 安裝，
python2.7並且python3.4. 該pip命令指的是 的包管理器python2.7，因此當您發出 時pip install urllib3，您正在嘗試urllib3為錯誤的 Python 版本pip3安裝/更新包 - 用於安裝/更新 Python 3 的包：$ pip3 install chardet urllib3 --upgrade --user順便說一句，我不喜歡呼叫
sudo pip/sudo pip3因為一些 python 包是由apt（像pip它自己，setuptools或者requests）管理的，所以如果你首先安裝了$ apt install python3-setuptools然後開始
sudo pip3 install打包，遲早你會破壞東西，因為setuptools許多python包被聲明為依賴項，你會不小心覆蓋python3-setuptools安裝。sudo apt install如果apt不提供您需要的軟體包或提供舊版本的軟體包，則更安全pip install --user。
