conda Malformed version string '~': invalid character(s)

创建环境报错：

conda env create -f environment.yaml
Solving environment: failed

CondaValueError: Malformed version string '~': invalid character(s).

需要更新conda

conda upgrade -n base -c defaults --override-channels conda
Solving environment: done

更新完毕后安装即可

conda env create -f environment.yaml
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound: 
  - gdk-pixbuf==2.36.12=haf2c3b9_1004
  - gcc_impl_linux-64==7.3.0=habb00fd_2
  - gxx_impl_linux-64==7.3.0=hdf63c60_2

这里由于版本问题，直接删除版本号即可，conda会帮你安装合适的版本

vi environment.yaml 

#改为：
 - gdk-pixbuf
  - gcc_impl_linux-64
  - gxx_impl_linux-64

#然后就可以安装了
conda env create -f environment.yaml
