python - ubuntu 14.04 pyenv 安装失败

Question

with command "lsb_release -a",

没有可用的 LSB 模块。

发行商 ID:Ubuntu

描述:Ubuntu 14.04.5 LTS

发布:14.04

代号:值得信赖

I followed this page, https://github.com/pyenv/pyenv#basic-github-checkout

但是安装失败。

1. 克隆https://github.com/pyenv/pyenv
2. 添加命令 $ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile $ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile $ echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bash_profile
3. source ~/.bash_profile 返回:没有这样的文件或目录

<小时/>

还有，我的echo "$PATH"是 /home/vagrant/.pyenv/bin:/home/vagrant/.rbenv/plugins/ruby-build/bin:/home/vagrant/.rbenv/shims:/home/vagrant/.rbenv/bin:/home/vagrant/.pyenv/bin:/home/vagrant/.rbenv/plugins/ruby-build/bin:/home/vagrant/.rbenv/shims:/home/vagrant/.rbenv/bin:/home/vagrant/.pyenv/bin:/home/vagrant/.rbenv/plugins/ruby-build/bin:/home/vagrant/.rbenv/shims:/home/vagrant/.rbenv/bin:/home/vagrant/.rbenv/plugins/ruby-build/bin:/home/vagrant/.rbenv/shims:/home/vagrant/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin

我该如何解决这个问题？

这也是我的 ~/.bash_profile下面...

[[ -f ~/.bashrc ]] && source ~/.bashrc

export PYENV_ROOT="$HOME/.pyenv"

export PATH="$PYENV_ROOT/bin:$PATH"

if command -v pyenv 1>/dev/null 2>&1; then

eval "$(pyenv init -)"

fi

MY TERMINAL PHOTO: bashrc exists and One&only

这是我的 ~/.bash_profile

Answer 1

此错误是因为 .bashrc 文件不存在。看起来您正在将 pyenv 环境变量添加到 ~/.bash_profile 并尝试获取 .bashrc 文件。

尝试获取您已修改的文件

source ~/.bash_profile

或者使用更改重新加载 shell

exec $SHELL
