为什么bash仍在寻找conda？

Question

我有一台装有Ubuntu 16.04 LTS的PC。 另外，我已经安装了Anaconda python发行版。 因此，在安装了pathos之后，我面临着这个无效的存档错误（类似于此问题 ）（我不确定它是否引起了错误）。 在尝试了很多问题后，我终于放弃了。 我认为最好卸载Anaconda。 我尝试按照此处的步骤操作（选项B）。 但这卡住了。 因此，我停止了该过程。 之后，我在这里尝试了选项A（我的.bash_profile文件不存在bash: /home/tejas/.bash_profile: No such file or directory ）。 但是当我在终端中输入“ conda”时，我得到

bash: /home/tejas/anaconda3/bin/conda: No such file or directory

表示该bash仍在尝试寻找conda？

此外，我还遵循了此问题中的所有其他命令。

编辑1：.bash_aliases为空。

bash: /home/tejas/.bash_aliases: No such file or directory

Answer 1

调用/home/tejas/anaconda3/bin/conda的别名或shell函数是一种可能的解释。 尝试这个：

type -a conda

它将告诉您外壳如何解析conda命令。

如果结果为空，则问题可能出在bash哈希命令路径的方式上，因此不必每次键入命令时都搜索$PATH 。 如果删除命令，则内部哈希表可能与现实不同步。

尝试这个：

hash conda

这将在$PATH搜索一个conda命令，如果找不到，它将删除该哈希条目。 之后，键入conda应该会给您通常的conda: command not found错误。

注意： type -a conda可能会导致bash重新检查conda命令的位置，如果找不到，则将其从其内部哈希表中删除。 因此，这可以诊断并解决问题。

更新：该问题已更新，表明有一个名为conda的shell函数。 anaconda安装程序必须已经创建了定义该功能的内容，并且仍在运行的Shell进程中存在。 您可能还需要设置一些相关的环境变量，例如$CONDA_EXE 。

删除定义函数和环境变量的脚本不会将其从正在运行的Shell进程中删除。

如果启动新的Shell，则可能没有这些定义（尽管如果从当前Shell调用它，它将继承任何环境变量）。

如果要在运行的Shell进程中删除函数定义，则可以unset conda 。

Answer 2

显然，您仍然定义的函数是导致此特定错误消息的原因，但是从您的问题中并不清楚它的定义位置或删除方式。

也许在您的主目录中使用grep表示CONDA_EXE ：

grep -F 'CONDA_EXE' ~/.[!.]*

如果那没有显示任何内容，则可能类似地在系统文件（可能在/etc查找它。 最终，揭示如何安装Conda以及从何处安装Conda，并可能更详细地说明卸载它的确切操作。
