Question

我一直在使用virtualenv，然后我也安装了anaconda。刚才我尝试使用像source activate helloworld这样的anaconda来激活虚拟环境。（事实上，我不记得这是否是我输入的命令）。然后环境被激活了。但是当我试图运行笔记本时，有人说即使我已经在那个环境中安装了它们，一些库也不存在。直到那时我才意识到我已经激活了错误的环境。然后我关闭标签并cd转到hellowworld，然后source bin/activate。但为时已晚了。我将此作为输出prepending /home/lcc/anaconda3/envs/bin to PATH并且预期未激活环境。你知道如何解决这个问题吗？谢谢！

以下是activate下的/hello/world文件的完整内容：

#!/bin/bash

# Determine the directory containing this script
if [[ -n $BASH_VERSION ]]; then
    _SCRIPT_LOCATION=${BASH_SOURCE[0]}
    SHELL="bash"
elif [[ -n $ZSH_VERSION ]]; then
    _SCRIPT_LOCATION=${funcstack[1]}
    SHELL="zsh"
else
    echo "Only bash and zsh are supported"
    return 1
fi
_CONDA_DIR=$(dirname "$_SCRIPT_LOCATION")

if [ $# -gt 1 ]; then
    (>&2 echo "Error: did not expect more than one argument.")
    (>&2 echo "    (Got $@)")
    return 1
fi

# Export whatever PS setting we have, so it is available to Python subprocesses

# Ensure that this script is sourced, not executed
# Also note that errors are ignored as `activate foo` doesn't generate a bad
# value for $0 which would cause errors.
if [[ -n $BASH_VERSION ]] && [[ "$(basename "$0" 2> /dev/null)" == "activate" ]]; then
    (>&2 echo "Error: activate must be sourced. Run 'source activate envname'
instead of 'activate envname'.
")
    "$_CONDA_DIR/conda" ..activate $SHELL$EXT -h
    exit 1
fi

"$_CONDA_DIR/conda" ..checkenv $SHELL$EXT "$@"
if (( $? != 0 )); then
    return 1
fi

# Ensure we deactivate any scripts from the old env
#   Note: this empties $@.  Preserve a copy.
args=$@
source "$_CONDA_DIR/deactivate"

_NEW_PATH=$("$_CONDA_DIR/conda" ..activate $SHELL$EXT "$args")
if (( $? == 0 )); then
    export CONDA_PATH_BACKUP="$PATH"
    # export this to restore it upon deactivation
    export CONDA_OLD_PS1=$PS1

    export PATH="$_NEW_PATH"
    # Get first path (should be full path prefix of our env)
    # inner string extraction pulls off first path
    # outer string removes /bin if present (on Unix)
    firstpath=${PATH%%:*}
    export CONDA_DEFAULT_ENV="$(echo ${firstpath} | sed "s|/bin$||")" &>/dev/null
    # Legacy support: CONDA_DEFAULT_ENV used to be either env name or full path if given as path.
    #    CONDA_DEFAULT_ENV is now always full path.
    #    Keep CONDA_ENV_PATH around, and have it mirror CONDA_DEFAULT_ENV.
    #    Last date of change: 2016-04-18
    export CONDA_ENV_PATH=$CONDA_DEFAULT_ENV

    export PS1="$( "$_CONDA_DIR/conda" ..setps1 $SHELL$EXT "$args" )"

    # Load any of the scripts found $PREFIX/etc/conda/activate.d AFTER activation
    _CONDA_D="${CONDA_DEFAULT_ENV}/etc/conda/activate.d"
    if [[ -d "$_CONDA_D" ]]; then
        IFS=$(echo -en "\n\b")&>/dev/null  && for f in $(find "$_CONDA_D" -iname "*.sh"); do source "$f"; done
    fi
else
    return $?
fi

if [[ -n $BASH_VERSION ]]; then
    hash -r
elif [[ -n $ZSH_VERSION ]]; then
    rehash

从您的问题中不清楚您的期望＆＃34;激活＆＃34;去做。它是激活virtualenv，还是激活conda环境。

安装miniconda或anaconda时，可以选择将其添加到PATH。如果你这样做，那么它可能总是在你的virtualenv激活脚本之前。您可以重命名其中一个，或者为virtualenv创建一个别名，使用激活脚本的绝对路径来调用它。你也可以移动Anaconda以使其附加而不是前置，但是随后将使用virtualenv activate而不是conda one（禁止绝对路径）。

要附加conda的路径，请查看〜/ .bashrc或〜/ .bash_profile并更改

export PATH=<anaconda path>:$PATH

到

export PATH=$PATH:<anaconda path>
