python 复制代码

conda create -n r4-base
conda activate r4-base
conda config --add channels conda-forge
conda install -c conda-forge r-base #或者 conda install -c conda-forge r-base=4.1.3

安装后进入R环境

python 复制代码

结果仍然是3.xxx版本

python 复制代码

(r4-base) /mnt/workspace/wzf> R

怀疑是新安装的R没有添加到路径中

查看R环境：

python 复制代码

(r4-base) /mnt/workspace/wzf> whereis R
R: /usr/bin/R /usr/lib/R /etc/R /usr/local/lib/R /usr/share/R /home/pai/envs/r4-base/bin/R

查看路径：

python 复制代码

echo $PATH

果然不在路径中，将/home/pai/envs/r4-base/bin/R添加到路径

python 复制代码

r4-base) /mnt/workspace/wzf> export PATH="/home/pai/envs/r4-base/bin:$PATH"

重新进入R环境，成功变成4.xxx版本
