ubuntu - 从要求 txt 安装包并失败

Question

我阅读了https://github.com/dennybritz/rnn-tutorial-rnnlm中的rnn教程并按照安装设置环境。但是我得到了我不知道的错误。我在 Ubuntu 14 的 virtualenv 中设置了它。我搜索了类似的问题并使用了他们的解决方案，但它不起作用。

我试过的方法:1. 更新gcc2. 重新安装 python-dev3. 安装libxxx(不好意思这个名字不准确但是有一堆乱七八糟的文件所以我记不起来了)

注意: 1.我不是ubuntu的专家，所以如果你能帮助我，希望你能提供详细的解释或解决方案，如果你有空的话。2.我试过重装ubuntu还是不行

看起来 ncurses 库没有安装。如果你在 Ubuntu 上，你应该先用

安装它

sudo apt-get install libncurses5-dev libncursesw5-dev
