Question

我的travis工作遇到以下问题：

Process Output:Could not find platform independent libraries <prefix>
Process Output:Could not find platform dependent libraries <exec_prefix>
Process Output:Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Process Output:Fatal Python error: Py_Initialize: Unable to get the locale encoding
Process Output:ModuleNotFoundError: No module named 'encodings'

我已经尝试过设置PYTHONPATH和PYTHONHOME，但仍然无法正常工作。有人可以帮我吗？感谢

export PYTHONHOME='$HOME/miniconda'
export PYTHONPATH='$HOME/miniconda:$PYTHONPATH'

当您删除默认的python库并且不替换它时会发生这种情况。例如，遵循不完整的升级说明。我遇到了这个并在ubuntu上解决了这个问题（对其他人应该是类似的过程）......

我使用（我知道sudo的过度使用）安装了新的python：

$ sudo apt-get update
$ sudo apt-get install build-essential checkinstall
$ sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

$ cd /usr/src
$ sudo wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz

$ sudo tar xzf Python-2.7.13.tgz
$ cd Python-2.7.13
$ sudo ./configure
$ sudo make install

这为我在/ usr / local / lib和/ usr / local / bin中创建了一个python2.7。然后我删除了/ usr / lib /中的系统python我认为我不想要两个版本和东西破坏了。因为新的python位于/ usr / lib / local中，系统正在查找/ usr / lib /。

$ cd /usr/lib
$ sudo rm -rf python2.7

删除系统python库后得到的具体错误是：

$ sudo apt-get install python-httplib2

要解决此问题，请使用新安装的python替换系统python（我之前做了前两个但是我想在这里显示一个正确的python交换）：

$ cd /usr/lib
$ sudo rm -rf python2.7
$ sudo ln -s /usr/local/lib/python2.7 python2.7

$ cd /usr/bin
$ sudo rm python2.7
$ sudo ln -s /usr/local/bin/python python2.7

然后事情再次起作用......

$ sudo apt-get install python-httplib2

找不到平台无关的库<prefix>
